i have a xj 98 jeep cherokee sport and after putting a reconditioned trans back in it, it wont fire, it has fuel and turns over fine just wont fire, i live in Australia and its hard to get any support here, any help would be appreciated.

 

Sounds like you have a problem with yoir nuetral safety switch. Bad comnection or just forgot to hook it up.

 

Just realized you said its cranking over.. probably broke yoir crank position sensor when putting the tranny back in.

 

thanks mate i may well be the cps at least im getting some help from the states its bloody hard down here

 

? Do you have two threads going?

 

u may have got some wires in the bellhousing when you boltedb it up

 

I'll post it here too.

Go stand on the drivers side with the hood up, shine a flash light between the very back of the intake manifold and the firewall. Look at the top of the bell housing and you'll see a small sensor with 2 bolts holding it in place. That's the CPS. It'll have a harness coming from it and should plug in on top of the intake manifold.

I BET it's either not plugged in or the mechanic didn't swap your original one onto the new transmission.

This sensor tells the coils when to fire. The Jeep will not run without it.

There IS a problem with that sensor. (You need a new mechanic.)

 

Thanks mate being an Aussie vehicle it will be on the passenger side thanks for your help this is a great web site as there is not much support here or the dealers want a fortune to fix it all good

 

yes mate new to this and being an Aussie doesnt help...lol

 

Oh yeah. Passenger side.

Go check it out and report back.

 

ok mate will do, its 5 am here so i better get to work and will reply this afternoon, thanks again Rob

 

Whew, 5am. That's early!

If you go plug that sensor in you can drive the Jeep to work.

 

Glad you figured it out. Sorry about the blurred responses from before, I was sending it from my phone.. Let us know if you need anything, I work graveyard in the Pacific time zone so if you really need help that moment, email me at flexj92@gmail.com

 

Gday Mate, apparently my jeep has not got the cps fitted so my mechanic says so i still have not got it going will email you to try and find out more thanks

 

Your saying you don't have a cps on your jeep? I cant imagine how else you would get.oir spark timing correct without one.
