Having problems with your Chevrolet Lumina ?

I have a 1992 Chevy Lumina Euro 4 door sedan with 160,000 miles on it. Recently, it has developed a persistant but intermittant problem of either dying at stop signs, or going out of gear (4 speed auto OD), or loosing all power and dying. When you restart it, it will sometimes be ok but other times stall as soon as you put it into drive. Then it will run ok for a while and perhaps die or make it home. I have replaced the ECM, Ign Module, IAC, Map sensor, O2 Sensor, all coils, Crank position

Answers :

All your problems appear like the car is losing the electricity. You detected a shorted wire. If the short was so strong that it burnt a wire then surely it has damaged others and their connectors - melted or partially charred (that act as a short) insulations , deformed connectors.\012\012\012
What is most likely happening now: as the error code says you have an intermittent short in the ignition - the damaged wires are loose in their connector and they shake around; sometimes they touch and short the ignition = the engine dies, the voltage on the battery drops and the gearbox disengages.
Check every wire from the harness and test every connector.
