SOURCE: f150 died while will starts but when

If the Engine light is staying on while the engine is running, this is where the diagnosis needs to start. The Engine Control Module needs to be scanned to find out which, of the many systems monitored by the computer is malfunctioning. That system will then have to be properly diagnosed to locate the actual cause of the problem. Only after this, can any effective repairs be made to your vehicle.

  • The EEC supplies power to the injectors. So you want to check the EEC relay and see if it is bad. This relay is brown and on the left side of the engine bay. The yellow wire and the red and green wire should have power to them. It's either the relay or a broken power feed wire in the harness. The red wire is the key wire to test for 12 volts with the key on.

Dual tanks on 1990 Ford F150

It should not cause no problems but instead of removing the tank leave it in the truck take out all the fuel in the tank and jus discontinue use of it. This will save you alot of time and trouble and i also suggest that if anyone besides you drives this vehicle then i would put a locking gas cap on it so it cant be accessed at anytime except by you.
