Hey guys. I have an 88 XJ 4.0 Automatic with 201,000 miles. It will start and run until I let go of the key. As long as I hold the key in the start position, the engine will stay running, can be revved, etc. Once the key is let go, it dies instantly.
I have replaced the following in the past 2 days:
The fuel pump with an OEM pump that tested good.
The Ignition switch at the base of the steering column.
Bypassed the Ballast Resistor on the drivers side engine bay.
Swapped around the 4 relays next to the battery.
After all that I have listed above, Still have the same problem. No broken fusible links noticeable, and the starter relay under the relay panel cover looks in good shape with no burned wires going to it. Crank Sensor, TPS, and IAC are all about a year old.
I am at a complete loss. This all happened out of the blue. Any help would be great. Thanks.
