fuel pump at stratup
does the fuel pump should run when you put the key to the ON position?
i thought it wasn't doing this before but since i did some work on the car, the fuel pump starts as sonn as i put the car at ON.
Is it normal?
I just put back the fuel pressure regulator solenoid, changed the FPR and the PD.
thanks a lot

With a stock ECU, the FP will not come on until the engine is switch to start and it starts. This is easily verified with a FP gauge.
With the PFC, it turns the FP on as soon as the ignition is turned on.

Yes it IS better to have pressure in the fuel system before you start cranking it.
