Greetings,
I have a no start on a 90 XJ 4.0 litre. It ran fine Wed night, Thurs morning...no start. It turns over like a champ but it wont catch and run.
I have no fire from the coil. The coil tests good. So in diagnosing the problem, I believe I need to check the following:
The crank position sensor.
The pick up coil
The ignition module under the coil
The ignition run circuit
What I dont know is what to test for (ohms, voltage, ect.) and where to access the test point. I have a circuit checker and a multimeter.
Thanks in advance...this is the first time my xj has me stumped and I caint find my Gol Danged Service Manual!
