Have you checked your crank shaft position sensor? I had starting and running problems. It turned out to be the sensor

well now i have to go buy a pressure gauge.
i bought and installed the new pump, not that hard just a little time consuming doing it
by myself. got everything installed and put back together, and now the engine acts like its starved for gas! cuts out when you try to accelerate, sputters and coughs when at idle, if it stays running at all. i did something wrong. now we have crap weather again, so it will be days before i can do anything again. i will probably take this one to a shop to fix now. working 7 days a week, 65 hours just doesnt leave time to trouble shoot!
thanks for the replies, this one wasnt meant to be!

|Evpjr||Make sure all of the sensors are operating properly. If any of them are not this can cause a "no start," condition.|

I take back that last post. According to the haynes manual, on 1997 and later models, the fuel filter is part of the fuel pump assembly. What the book says about the fuel system is check the pressure off the fuel rail. has to be done with a t adapter. the fuel line passes through the t adapter and the guage comes off the bottom of the T.
so its like this
<fuel line> ====== T ===== <fuel rail>
nevermind the periods, they are only to show relation in the picture.
The book states that if the pressure is between 44-54 its ok. below 44 replace the fuel pump. above 54 replace the fuel regulator.
this is valid only for 1997 and later models. any earlier the check procedure and pressures are completely different.

I would check the fuel filter also, it is much cheaper to change that out than the pump.
I am starting to have some hard start problems, kind of a rough idle, I know I have 88000 miles on this fuel filter.
I do not hear a whine from my pump either.

|ttim||forgot to put that in the post..i dont have the fuel pump whirl sound of it priming itself now.|

|KSGoldenEagle||I just went through something very similar to this and it was the fuel pump. Check if you can hear the fuel pump "whine" when you turn the key on. Also on mine, when it would just crank but not turn over, I sprayed some starting fluid into the throttle body and it would start and run until that ran out....try that too. You'll know pretty quick if it's just not getting fuel. Good luck my friend.|

06 tj starting issue
a few days ago, started the jeep in the morning, it ran for a few moments, then stuttered and died. but started back up
fine. this happened twice more, and then this afternoon, no start. it turns over easy and fast, just wont kick off. im
leaning towards fuel pump, but want to make sure because of the cost of these items.
ive swapped the relay for the fuel pump with the horn relay. no help.
jeep has the fuel rail, ignition rail setup (i think thats what its called...no plug wires) so i have not yet pulled a plug
to make sure it was getting spark. actually, im not even sure how i would do that with this setup.
i dont have a fuel pressure guage to hook up and test, but i could pick one up tomorrow, along with the pump.
(one of the few sucky things about living in evergreen, not having options on saturday to pick up parts!)
of course my tank is full, and i have aftermarket skids under it. not a big problem, i just hate balancing a full
tank on a jack to get it up and down.
anything else you would suggest?
