NEED HELP! please read and help if you can
 

OK i have a 94 Cherokee sport 4.0. now heres what its doing. i can be sitting at a stop light or even driving down the road and it will just die. it happened a few times one day then a week later it happened again and then it started doing it daily and most the time it started right back up but this last time it died 6 times with in 6 miles and during that time it took 30 minutes before it would start again and now it wont start at all. any info or help would be appreciated

It could be alot of things

Fuel pump, vacume leak ,distributer etc.

How does it drive when it's driving?

it drives great no problems it just dies. now i can hear the fule pump prime when i turn the ignition but i know that doesnt mean alot but i know it primes

It could also be the cps (crank position sensor).

You really need to go over everything. Start with basics

oh boy that dont sound good

Try this first, Take the negative battery cable off for a few mins. Then put it back on,this will reset the computer. See if it still does it then.

ill go try that

ok that didnt work it was worth a shot though

I didn't read that you said it wouldn't start at all now.

Does it turn over anymore

ya it still cranks but just wont start

Did you try starting it in neutral

its a stick. i tried with the clutch in and out

You need to check if there is any codes

ya i thought about that Advanced auto parts does a free reading but its getting it there to do it but ya that is something i need to do

have them check your fuel pressure too

You should pull your distributer cap for ****s and giggles

I know the cps usually get all greased up and gives a false read. Usually it just needs to be cleaned. Tuff getting to it though.

yup have codes checked and sounds like a fuel issue to me. but get it checked out and go from there

Tuff is an understatement! lol. I had the same problem and symptoms with mine about ten years ago. Tried using ether to fire it up. (bad idea, by the way...) It was an intermitant problem at first, usually letting it sit for 20-30 minutes and it would start... eventually she stopped starting, just crank and crank with nothing. It turned out to be the Crank Position Sensor. The dealership told me what the sensor does, but admited the main function was to short out IF oil leaked down onto it. In Jeeps (as we all know) it isn't a matter of if, but a matter of when the oil shorts it out.

To get to the damn thing you either need a ton of extentions and a few "wobbly" adaptors or you can drop the tranny, or lift the engine out...personally I would go for the extentions. After I replaced mine, I used a long chunk of tubing and a silicone caulking gun to seal the switch area up. Like I said earlier, that was almost a decade ago, and the new one has given me no worries.

Good luck!

thanks ill try that. i was hoping someone had the same problem and could tell me what they did thanks. if this happened to someone else also please tell me what you did to fix it incase this isnt my problem but it might be since i do have an oil leak

check to see if it has spark when its turning over that will tell u whether its a fuel or spark issue. a spark issue could be the cps, bad ground or distributer cap, rotor, if it has spark and wont start than it will most likely be a fuel problem. Do this before you do anything... this will be the easiest way to tell if its a fuel problem or not.

sounds like altenator to me

I agree, it could be the alt. I bought mine with a busted alt, and the gauge read 12 for a few miles, then it nose dives past 9. It will run on just the battery but then you drain the battery out. If that happens then it doesn't start obviously. Just another suggestion. CPS idea also brilliant.

CPS. If it was a fuel problem the eng. would starve out then quit. With an electrical problem it's switch off. Nothing! This is what a CPS does, switch off.

In my opinion you won't hurt yourself in any way to just replace the thing as a matter of course.
