Will start then shut off
The truck will start then shut off after about 6 seconds. I
have replaced fuel pump fuel filter and cleaned mass
airflow, and replaced relays. I can spray starting fluid and
will keep running until I stop spraying.
So that means the fuel is shutting off, now you need to find out if the security system has been activated, anti theft light on steady? Read the owners manual on how to reset the system on this vehicle.
I actually wired the fuel pump strait to the battery to see if that would work and it didnt. I haven't seen a anti theft light
The security system can shut off injector pulse, if you have a NOID light or LED test light you can check for injector pulse during failure.
