So 95 xj Sport, OBD1, 4.0 auto.
No spark
What I have tried:
checked codes: no codes
I have +12v to the coil.
I am not getting a pulsed -ve ground when cranking.
I believe the 2x cps are good and working, the node light on the #1 injector flashes continuously when cranking.
previous experience has shown when either cps is not working I only get an initial pulse on the injector node light then nothing. Also getting a strong smell on petrol when cranking.
I have continuity ( .2 ohm ) from the -ve coil loom plug to pin 19 on the pcm.
re checked the pcm ground connection-its good.
swapped in a known working PCM, same symptoms.
History: was driving fine no concerns, pulled it in to shed for oil and filter change and cooling system flush. no crank no spark.
just for shits and giggles I plugged in another coil- no spark.
Any ideas?
