What is missing during the no-start, fuel pressure, fuel injector pulses, or spark ?
Failure of the PCM should only be considered after complete and in-depth trouble shooting and diagnostics of the more common and more logical causes for the symptoms described.
Did you install a genuine Jeep Crank Position Sensor, or a cheap crappy Chinese clone auto parts store CPS ?

So a no start = PCM ?
What diagnostics have we done ?
Attached scanner and observe data?
checked for codes?
12v at coil?
12v at injectors?
Try this as someone tries to start jeep spray carb cleaner into throttle body - did it fire and try to start?

I have a 2005 Wrangler 4.0 that cranks but will not start. Pulled it in the garage last week and it was running fine. Went to use it a week later and it cranks strong but does not start. I have changed the crank sensor but that did not help. I'm thinking it may be the PCM. Is there a simple way to check it and if it is the PCM does anybody have an idea where to get a replacement?
