2.5 YJ Starts sometimes, and just cranks every other time.

So check it out, I've been trying to deal with the jeep not starting, but reading everyone elses problems and answers. Here's the deal. the jeep started dying on me in the rain. Not sputtering, but actually cutting off while I was driving, then firing back up enough to drive it until it cut off again. It finally died on me that night for what seemed like for good. Got it home and started working and testing it. It cranked and cranked and cranked but didn't start. Was getting fuel and the pump ran. No spark, replaced the coil, cap, rodder, plugs and threw in a fuel filter. Still nothing. Hooked it up to the computer and found out that the coil wasn't getting and power to it. As smart as I was I went and replaced the ignition control module, not cheap!! It started right up and idled, took it for a spin, brought it back to the house, turned it off and tried starting it again. To my amazment, once again nothing, it just cranked and cranked, but didnt' start. Today it started up and ran, it was becoming consistent in starting up sparatically. Wait a few minutes, or a few hours and it would start again. Well it died at a friends house, so as I have researched somemore it could have been the crankshaft positon sensor. Replaced that and it fired right up. Got it home, turned it off, tried starting it again and nothing, just cranking and cranking and cranking.

Sorry for the story, but this is where I am now. Confused and getting lighter in the wallet! It's reminding me of that old movie called Christene. You know the car who had a mind of it's own. Guess it's just a jeep thing, but it'd be nice for it to start consistently, being as it was 80 today.

Would appreciate any suggestions, I love my jeep and I don't want to bring it to a garage.

It doesn't matter what's right, it's only wrong if you get caught

I had the same issue on my 94', I purchased a re-firb computer for a couple hundred bucks from Auto Computer Exchange - Auto Computer Superstore - Cheaper than dealers and mechanics. and its been great since. It is an option, if you have money and no time... But if you have time and no money, rip into it!

I changed it in 9/2009, its been over six months of cold starts at 7am in Michigan... not one hesitation.

happened to me...

...not sure this will help - but i have a '90 wrangler which was doing that same thing a few yrs ago - i did most of what you did - finally a guy came over & took a look for me...turned out that because mine was a sept/oct model that some parts (the starter module) was different - he put on a larger ('91) module & boom - didn't happen again...may want to check it out - good luck,
