Message	thought i might post a question for our resident wiring guru. does anyone know how the fuel pump wiring controls the priming of the fuel pump??? the pump runs either constantly or just for a certain amount of time..... i ask because my aftermarket engine management primes my fuel pump for 40 to 50 seconds every time i turn the key... and with my nismo pump it is killing my battery.. the manufacturer of the ecu wont help either and say that i cant modify anything in the ecu software to change the "prime time" id much prefer it to prime like a stock z.. 10 secs max is there a way to wire up the fuel pump to manually prime the pump through a switch and let the stock wiring control the normal operation ? fpcu has been long binned btw
