FAQ's-jeep wont start!

sticky please.

If your jeep wont start, this is to help you troubleshoot your problems...

There seems to be alot of people with the no start problem. Dont know if its the weather or the rotation of the earth, but maybe this will help at least keep some from asking the question when its already been asked on the same page. This will also hopefully keep you from buying a starter when you dont need one, or buying a battery when you dont need one. if you really want to spend 100 bucks really bad, i accept PAYPAL, and ill work out a payment plan if necessary.

TROUBLESHOOTING-


this is a straight copy and paste from the autozone website-
Don't buy a part you don't need. AutoZone will test your car's parts for free. We can test your car's battery, alternator, starter and voltage regulator while they're still on your car. We can also give your car a complete starting and charging systems test.

You can also take your alternator, starter or battery into our store and we'll test it. In most stores, we can also test voltage regulators, control modules, coils, throttle position sensors (TPSs) and other engine management components.

although taking your parts to autozone for a free test is a good idea, also call other parts stores in your area before buying your new parts. youd be suprised. sometimes other stores are as much as 10 bucks cheaper, sometimes autozone is as much as 10 bucks cheaper. if you really dont care about spending 10 dollars, please send me 10 dollars. pm me for my PAYPAL info. sorry, but at this time i cannot do a payment plan on 10 dollars.

1. If your jeep wont start, theres certain things you should check first BEFORE POSTING IT IN THE FORUM, because we are probably just going to tell you to go check these things.

A. open the hood.

B. visually inspect the battery. there should be no corrosion on the terminals. if theres corrosion - rust or white stuff - clean it off. use a wire brush, or a hard bristled brush, and baking soda/water mix, or cola, or even a special spray they sell at walmart or autozone. your best bet is to also disconnect the battery- negative side first, and clean the inside of the connections, and the terminals where the connections sit. reconnect the battery positive side first, then negative. yes it will spark a little when you connect the negative.

C. grab the big wires coming off the battery. start with the negative side. try to jiggle them back and forth. there should be no play. they should be tight. repeat this step for the positive side. if its loose, tighten it up. if it wont tighten you might need to replace the connector. they sell them at walmart and theyre cheap. if the other side is tight, but looks bad, replace it too. why not?

D. put the keys in. turn the jeep on. (dont start it). move the key from the off position, to the position BEFORE the starting position. if it trys to start youve gone too far. move it back to the off position. do this 3 times total (2 more times if youve already done it once duh) within 5 seconds. the dash lights should come on. once they go off, keep an eye on your odometer. the check engine light will flash. if it doesnt then your check engine light bulb is out. it will display numbers on the odometer. write them down. the last number should be 55. this means the test is over. this might not diagnose your battery problem, but hey there might be something wrong you didnt even know about! btw, this method is called the ''key dance''.. for lack of a better term, or having to type out self-diagnostic.

E. turn the jeep back on but dont start it. turn the headlights on. get out and look at the headlights. they should be bright. if they are dim, you probably have a dead battery, wether its the origional reason your jeep wont start depends on how many times you tried to start it. you might have ran the battery down trying to start it. you cant just go off the battery guage on the dash, i recently had a battery that tested bad, but it was showing 12v on the dash.

if the lights are dim- take the battery out and take it to autozone. they will charge it for free, and test it for you for free. i suggest dropping it off, because you probably dont want to sit at autozone for more than an hour waiting.

if you have a charger, put it on the battery. it will take a while to trickle charge, but you cant start a jeep with a dead battery.


F. If your headlights are bright, then your battery isnt completely dead. now either have someone stand in front of the jeep, or if its parked in front of a wall or garage door, put the hood down so you can see the reflection of the lights on the wall or door. try to start it. if the lights turn off or dim while its starting or trying to start, your battery is low. charge it yourself or take it to autozone.

G. If it starts, but acts like the battery is weak its usually but not always accompanied by the dimming of the dash lights/head lights.

H. If none of these above problems above help you, it might be your starter. take the starter off and take it up to autozone, they will test it for free, and you can even watch if youd like.

here is a good how-to on taking off and replacing your starter.


Jeep Horizons :: Jeep Wrangler (TJ) Starter Replacement


I. if all else fails, of like me, you tend to skip to the last step when reading instructions, remove both your starter, and your battery and take them to autozone. if one is bad, you already have the old one there, so no paying a pesky core charge! Also, just because your battery is dead or bad, doesnt mean you NEED an optima yellow top battery. a regular black duralast battery will work fine. i opted for a duralast yellow top. buy whatever battery you want. its up to you!

please refrain from buying any gay stickers for your jeep while your up there. if you do buy gay stickers, put them on your neighbors car, or your wifes car only. the only authorized stickers for your jeep are genuine mopar, jeep, or chrysler stickers, or stickers from companies in which you currently have one or more of their products installed on your jeep. Be advised that putting audio product stickers on your jeep is an advertisement to thieves that you have aftermarket audio equipment for them to steal.

i gotta say do not rely on autozone to test your parts. i've had countless people on this forum asking me about no starts. and won't believe me on something, cuz autozone said its ok. then when they finally replace a part autozone said was good, it ended up being the problem.

no crank no start is an easy thing to diagnose. beyond the battery stuff, you need to know if power is at the starter solenoid, and being switched to the starter motor with the key in the crank position. requires two people and a $10 test light. if power goes to the starter motor, and no crank. starter is bad. if no power there, then there's issues with wiring, fuses, ignition switch, clutch switch and so on.

i guess my only point is, instead of removing your starter, and taking it to autozone, just test it with a buddy helping, very easy.

or the time proven easy test is whack it with a hammer while someone is cranking it, if it starts that way, the starter was the problem, doesn't mean it isn't the starter if the hammer doesn't make it work though.

I agree, why would you trust someone who's job is to sell you something.

no need to trust them....

STAND THERE AND WATCH THEM TEST IT..... DUH?

now as far as needing that $250 optima battery, yeah dont trust them... but ive always had good help from my local autozone. the manager is a jeep guy, and the cashier/parts driver chick is hot..

but i dont always go there. i get whatevers cheaper, be it advanced, or online, etc..

but yea, if your so worried about autozone trying to sell you something... understand that they are paid HOURLY lol.

HOURLY.

they arent salesmen. salesman make commission.

and if you still dont trust them, then just stand there and wait and watch.

ya but even if you stand there and watch them, if the equipment says a bad part is fine, whats the point. seriously, countless times people tell me, autozone said it tested good, and once i finally replaced it, that was the problem.

it is possible to find a good autozone, but 99% of them suck, and once you get a couple bad new parts out of the box, and bang your head for days before trying another part you just replaced, you'll agree. nothing sucks more than being right, replacing the part, still not working, try for hours to figure out where you went wrong, then say screw it, i'll get another one of those parts, and that was it. or put in a starter, that starts the jeep, but makes noises, or doesn't work intermittently. all the discount parts stores are getting worse.

carquest and napa are all i'll use. their rebuilt electrical parts usually have a 2 yr warranty, and they'll last beyond that. i'd rather have that, than a lifetime warranty you'll be using frequently. cq and napa also have many lifetime warranty parts as well.

can you tell i'm passionate about idiots in the auto industry, between jiffy lube and the like, then discount parts stores, and then the direction the dealers took with their service, i got some issues with a lot of the places in the industry i'm in.

Why not ask the Autozone "advisor" before his mind gets distorted with things about cars.
You want him to help you with fresh new ideas, not 2 weeks worth of "knowledge" becoming their "expert."

Ask him before he works for Autozone - avoid the rush.

Talk to him at his present job - at the drive through window at McDonnalds. You know, the one that cannot understand complicated orders, like "No Pickles."

Decent suggestions but as we all know it could be a million little things that cause the problem but if you are not really competent with engines this a decent guideline.

+1,000 on the thought of fag jeep

for the newbs

priming the fuel pump = turning the key to the position before starting it.. youll hear the fuel pump kick on and make a soft buzzing sound.

turn it back off.

turn it on again - not starting it, just to the click before that- and wait for the whirr of the fuel pump.

usually takes 2 times, then when your turn it on - not starting it- by the 3rd of 4th time you wont hear that whir anymore

that rules, I thought it said Fags jeep won't start as well...

Remember the basics for no start issues. An engine needs three things to run normal,

1) Compression
2) Fuel
3) Spark

At some point, your not getting one of those three things. First, isolate the problem.

Will it crank over? If not, probably battery or connections, or locked up starter, etc...

It will crank but not start - very common. Crank it over for a few seconds and pull one spark plug, is it wet with gas? If no, then your not getting fuel. If yes, your not getting spark. Test for spark with the plug out, if no spark, focus on the electrical systems. If there is spark, focus on the fuel system. This narrows your troubleshooting by 50% to not waist time.

Based on spark or no spark, you should be able to continue troubleshooting each system. For no spark, check coil, check wires, check ignition, check grounds, test each component, check for wore wires sparking on the block before it hits the plug, change plugs, change distributor cap and rotor, etc... Somewhere, there will be a breakdown in the system.

For no fuel, check your fuel pump (does it growl when you hit the key to on?), fuel filters, power to the injectors, fuel lines, etc...

In the rare case that you do have spark, and you still have a wet spark plug, there is most likely water in the fuel system or your plugs are fouled and should be replaced.

Just the basics I can think of off the top of my head... Most of the no start issues I encounter are either an old battery that will not keep a charge anymore (usually older than five years) or loose cables. Loose cables and dirty terminal connections make up about 90% of the problems with starting. ALWAYS check those first, pull 'em off the battery and clean with sandpaper or a wire brush to ruff 'em up really good. Same inside the terminal connector then lock 'em down.

Went over to troubleshoot my mother in-laws chevy cavalier this morning, for her no start issue, she wore out the ignition and the key just is'nt doing it anymore. Heavy keys reak havoc on ignitions. ...remember that folks, you'll thank me later.

In her case, we turn the key to on, then jump the selenoid with a screwdriver to start it. She has (2) choices, 1) replace the ignition in the stearing column for a lot of $$$ or 2) hook up a starter button. Turn key, push start button, bypass ignition

She does get positive voltage sometimes, just have to wiggle the key in there as your turning it to start. Thats how we knew the problem was in the column... and with close to 200,000 miles, we'll go with the starter button.

Precisely why my Lotus' keychain has only the Lotus Key, gas cap key and keyfob.

My Jeep key has only the Jeep key, BMW key, tuffy console key, and gas cap key on it.

All other keys are on a third ring(house keys, gate keys, toolbox keys, and a few others.. you'd think having three rings in your pocket is a PITA, bulky, but its really not bad at all.

Women, esp young ones, are horrid about a bunch of useless crap on key chains.

FWIW I also thought I read FAG JEEP....had me all sorts of confused. then I said to myself "self, do you think that might be a q rather than a g?"

Ok my 1989 jeep 4.2L will not start after driving it for 30 minutes or so. If I let it sit for 5 minutes after driving it, the jeep will not start. The jeep crank over, but will not catch a spark it seems. If I let it sit for 30 minutes or let it cool down back to 150 degrees it will start. I'm confuse. It have a 470cfm 4bbl Holley carb with electric choke. Someone mention I may have a vacuum leak.
