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.

 

hmm well i have a stock ecu and the fuel pump strat even before i start the car, i have a FP guage and the pressure is rising before i start it.

I suppose it is a good trouble than, isn't it?

Well, you probably have a Canadian spec FD. I don't know if it is different from the american spec FDs, but my stock ECU was the same as cewrx7r1 mentioned. It wouldn't pressure the fuel system until I started turning the engine, and when I bought the PFC, it DID start to pressurize the fuel system before I cranked the engine.

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