Hey guys!
I'm from Norway so excuse my bad english....
I have this 91 xj,4.0,Lim.,auto. and I have'nt been able to start the damn thing for 8 weeks!!!! I have tried almost anything, also measured the signals from both the CPS and Sync sensor with oscilloscope, seems to be good signals even at the input terminal at pcm, tried to changed the pcm, measured coil, changed rotor, cap, plug wires etc. Tested compression!
Also tried various settings for the distributor/rotor assembly!
I've also tried to short out the ASD and fuelrelay to get increased gas pressure.
It's just like its going to start, then dies after 1 sec and when I look at the spark, it seems to be one good spark and then it "fades" to just rarely one bad spark occasionally.
Desperately seeking answer????????
