Fuel injections are getting fuel but, the truck still will not stay started.

    The ECM is located behind the dash on the passenger side, you will need a wiring diagram to proceed with testing. If you have fuel injection it means the ECM is receiving power, seeing crankshaft rotation and processing this information to trigger the injectors. Do you have ignition or does the truck loose ignition once the ignition key is released from the start position? If the engine starts and runs it must be mechanically sound.
