Stock '89 Limited 4.0L Automatic AWD. 172k miles.
This started this morning during todays blizzard.
Jeep is running fine. Pull in driveway put trans in Park and turn off the key. Engine continues to run.
Moved key back to ON and notice all the Accessories go back on like heater fan, radio, etc...
Turn key back to OFF and all accessories turn off but engine continues to run. I noticed the 4wd light is still on even if the key is off.
Open hood and pull one wire off of the Ballast resister and engine stops. Reconnect and restart engine fine. Turn key to OFF and again engine keeps running. I also noticed a stronge smell of gas.
At this point I notice that there is gas leaking from the fuel rail. I pulled the wire off the ballast resister again and the leak slows to a stop after engine stops.
I'm looking at the wiring diagram in my Haynes manual now but I could use some suggestions/info.
If everything kept running like the radio etc, I would suspect it's the ignition switch but the accesories turn off correctly.
Fuel problem is scary. Where is the fuel pump relay located? I may want to pull it while I troubleshoot so the engine doesn't go up in flames.
