97 XJ Shutting Down
This has probably been asked before, but I can't find a solution using the search function. I've got a 10/1997 XJ Sport that I've owned for the last 5 years. It's had an intermittent fault where it would start then shut down the same as if the Security light is on. In the past if you locked then unlocked via the key fob it would run, the battery has been replaced a few months ago in the fob.
So the fuel pump is ok, 52psi & 250ml in 7 sec, as per the XJ manual. Crank cam sensors appear ok, the engine is starting, just shuts down within seconds.
Tested the loom for loose/broken wires, nothing shows up.
I probed the injector wires & when it stops the injectors are turning it off, the ignition is still firing. No codes are showing up with the elcheapo scanner. The ASD relay is still alive after the engine stops, so it isn't stopping the engine.
My thoughts are the PCM or the Security system. How can I bypass the Security system to eliminate it? I don't have another PCM to swap over & the nearest Jeep dealer is 120kms away.
Any other thoughts would be much appreciated.
