ok im about to set my XJ fire here......... it cranks but wont start, and the symptoms are:
-no check engine light when in "on" position
-no voltage gauge
-no gas guage
-no spark
-no fuel pressure
-and no start

i've replaced:
-new CPS (checked and tested ok and turns out the old one is too >=(
-new cap and rotor
-new PCM

someone please help or this jeep is going to the scrap yard

 

bump.

 

maybe your coil is bad,

 

but my check engine light is out? thats gotta be PCM related.

 

Check the fuses in the power distribution box under the hood, this happened in my '91 my jeep was out for 4 days and I replaced the fuel pump them I figured out it was the fuse

 

yup check all fuses (kick panel and PDC) 2 times all fine. even swapped relays for ASD and starter and stuff and still nothing.

 

how about the pcm connector, corrosion on the pins or what have you

 

i'll check them out 2morrow. but they seam fine...... my 2 guesses are: PCM not getting power (hence check engine light not turning on, and no volt/gas guages), or the only other thing i could think of is distributer completely shot (like the cam sensor or something?)

 

nope its checked and good.

 

WAHOO!!!!!!!!! i found a wire that fried and i pieced in a new one and i have the PCM back!!!! it even studdered when i tried starting it! only problem now is no spark! any help?

i have voltage/gas gauges back so just gotta find the no spark!

 

Getting power from the ignition coil? Also, you said that you swapped in a new distributor cap and rotor. Leave anything disconnected?

 

nope i double checked the cap/rotor. ill have to check out the ignition coil then.......
