i am having a problem with my jeep cherokee not firing at all.Pulled off the coil wire not getting fire there either.I replaced the coil...wires...dist cap...rotor button...cps and still no fire.Would there be anything else that i could check b4 i shell out the money for a new ECC?What fuzes or relays would stop it from firing?By the way it is a 2 wheel drive and has a 2.5 engine...please help if yall can

Nuetral safety switch. Are you getting fuel? (fuel/spark/air is needed)
There a million no-start threads on here, keep searching and poking around the forum.

yea...its getting fuel and its a 5 speed so it wouldnt have a neutral switch would it

check the tranny censers the injector censers and all the censers make sure they are all plugged in if they arnt you wont get anything good luck if you have any more problems hit me up with pm

edit: and no i start mine in first all the time

Crank position sensor, replace the f-ing crank position sensor for crap sakes! A neutral safety switch will cause a no crank problem, you have a no spark problem. Do a search on "no spark" and you will see that the crank sensor is the problem 99% of the time.

that was the second thing i put on it was the cps..the first thing was a coil because it was cracked...that wasnt the prob though

Could be the cam sensor, the ASD relay, or the #20 fuse (I think that is the correct number fuse) under the hood. PCMs don't fail very often.

i am having the same problem. i replaced the cps and coil and still no spark. after i did all that i was checking all my fuses under the hood and the eng control fuse was blown. i put a new fuse in there and it just pops when i turn the key on. now i put a jumper wire in the and it didnt get hot and it fired right up. i started to have all these problems after a trip up to the badlands. i went into some deep water and some mud. i was wondering if i need a new ecm. oh its a 95 with a 4.0

Come to think of it i also had a jumper wire in my fuze box too.My wife had the jeep b4 we got together and had some trouble out of it and some ppl stopped and helped her and she said he told her he fixed it temporarily.That was 8 yrs ago and come to think of it the jumper wire is not there now but i dont remember what it was jumping

haha.. mine was jumping the eng control fuse. my buddies little kid wanted to go wheeling so i rigged it so i could take him. i was thinking about keeping it that way for now. i am thinking its a pcm problem, i just dont have the money for one right now haha

If that fuse is blowing, check the wiring to the O2 sensor for a short to ground.

chreokee1972

yea....$250 for mine brand new....debating on taking a chance on one from a junkyard

chreokee1972

Busted,would the o2 sensor be the one on the exhaust or exhaust manifold?

warped156

thanks bustedback... i was changing my upper control arm bushings and we moved the o2 sensor wire and i put it back on the bracket. i am goin out there right now to check it out// thanks again man....

warped156

that was it i moved the wiring off the oil pan and it fired right up.. thanks again i would have never though of that.
