Hello all looking for help on my jeep. I have an 01 xj that ran fine uo until 2 months ago. First thought it was the fuel pump, but has passed pressure test. Read some other threads that said it could be the computer, since i have already replaced all relays. I did replace computer with no luck. The fuel pump just seems to keep priming when key is turned to on position, but will not start. I have no idea what elso to check, i also read on other forums that it coukd be the crankshaft position sensor, was looking to see if anyone has had the sane issue?

 

Do you have spark?

 

yessir, a couple of times it'd start. But stop almost instantly. Originally the fuel pump relay was clicking loudly so i replaced that and the asd relay

 

It could still be a bad coil rail that's intermittently failing. I'd check that and of course you can test the CPS, maybe do that and if that tests OK then move on to test the injectors.

 

Check codes yet ?

 

i will be tonight i had it running for the last 4 days ran like champ, but the temperature out side was warmer, this morning i would not start however and it is colder out now idk if that has to do with anything

 

my xj will now start when outside temperature is above 40 degrees, any colder and it will not start. Also am getting a p1694, any suggestions?
