So I am trying to start but it only cranks.
The fuel pump does run for 2 secs after I switch on.
When I try to start, the fuel pump does not run. Fuel pump is from the same truck as the engine.
The injectors do get 12V positive but the PCM does not give ground.
I disabled VATS and had a segment swap done (using 4L60E instead of 4L80E).
I also removed all smog equipment from the harness and disabled it in the PCM.
Does anyone know what can be bothering me?
I was thinking, maybe VATS hasn't been disabled. Maybe some ground trouble or some sensor (MAP ?)
The engine is a LQ4 from a '04 GMC Sierra 2500 HD.
Thanks!
