While pulling my loaded trailer with my 1989 Dodge Van 15 Pass. B350, both fuel injectors went wide open flooding fuel over the top of the carburetor down onto the top of the motor and to the ground. II lost about 2 gal. Of gas It has not started since that time(january). Several mechanics have looked at it but have not found the cause. The Scanner shows a Auto Shutdown Relay problem. We can't find any schematics that shows us where the Auto Shutdown Relay is located.I have replaced the ECU, both fuel injectors, and the fuel pump relay. Can you help?

What happens now when you just turn the ignition switch to "run"?

The ASD relay is not the problem. It is supposed to be on all the time the engine is running. It supplies power to the injectors and ignition coil. The automatic shutdown relay should only run for one second after turning on the ignition switch, then again during engine rotation, (cranking or running). To tell if it is turning on during cranking, measure the voltage on the ignition coil positive wire. You should find 12 volts. It must go back to 0 volts when you stop cranking.
