Hello,
I'm wondering if there is a way to command the fuel pump to prime @ key on. Right now the PCM uses some kind of algorithm it primes if the car has sat for 30+ minutes or so @ first key on. Every other key on it does not prime, wondering if there is a way to change that somehow without rigging a timer relay? I know in HPT there is a way to increase pump prime time but this does not address the no prime @ key on more than once issue I'm facing.
I'm trying a experiment which involves no check valve so my fuel pressure drops as soon as the fuel pump stops priming, I don't want the check valve for this experiment so I want to get the ECU to prime each time on key on.
Thanks!
