ok so im working on this 200o cherokee limited that rats ate most of the under hood wiring. ive replaced everything i can find cant get it to start. i replaced the crank postion sensor since it was ate in half with a new one from the dealer, it sounds like its getting spark now.
im not getting any power to the injectors at all. any suggestions? could the computer have gone bad from sitting for 3 years? im at a complete lose with this one. ive got to get this thing running asap. thanks

 

ok so after reading some on this site it looks to me that the cam postioning sensor also controls the fule injector pulse. is that right? whould that be the reason why theres no power going to my injectors? im at a complete lose with this one...

 

Why not get a new harness for the junkyard or from someone on the site or buy a new one. If it's all chewed up I dont think you will find all the problems. As far as the com. you will either have to test it or buy another or look for one on here. Really hard to tell if its still good or not with bad wiring but I wouldn't think it would just go bad from sitting.

 

ive rplaced all of the harnesses that where destroyed, thats why im confused about this problem. is there anyway to check the cam sensor?

 

also just talke dto a buddy that works at the dealership he says that the pcm may have gotten a short n fried the driver from it. this is turning into a bg headache lol

 

Anything could have happen to the pcm like your friend says it's just something you can't really tell till you try it out can your buddy do maybe a scan on it at the stealership? As far as the cam sensor I'm not sure try the search on this site maybe someone posted up something in there I'm just not sure on which type of test will work on it maybe a resistance test on it.You'll get it working just anything electrical is a pain in the azz cause it only takes something small to make it look like a totally differant problem.gl
