1990 XJ 4.0
So I haven’t been able to drive jeep for 3 months now, and its really putting a dent in my life.
Sometimes it starts, I can drive it around. Others, it starts up, runs strong, while key is in crank position, and then dies when I let it go to the on position.
I have replaced:
Ignition Switch
CPS
Fuel injectors/orings
Fuel filter
Spark Plugs
I have thoroughly cleaned TB and related sensors.
I have bypassed the fuel pump ballast resistor with a section of wire.
I’m running out of options, and I don’t know where to look next- every bit of advice I've scoured from JU or leads me to the things I have replaced.
Please, any other advice is greatly appreciated. As a side note, it doesn’t seem to be electrical, the Optima red top maintaining voltage supplying power start after start, alternator is less than a year old, and works fine when jeep actually cranks, and the starter is definitely doing its job.
Thanks,
Paul
p.s. Last night, after hooking up ignition switch, started her, she ran- drove her across parking lot, turned off, started , fine- I repeated this action- start, drive, stop 3 or 4 times--- This morning, went out to start, cranked, let go of key, and she died
