ok so i recently notice my fuel pump stays running when i turn the key on to the on position. i have tried the 12V mod before but didn't like it due to the fuel pump stays running all the time so i switched back to stock. everything was normal for over a year, the 2 wires that i stripped was soldered and shrink wrap so no loose connection there. sometimes when i start the car i can hear the fuel pump going from loud to quiet and vice versa and that's only on idle. can the fuel pump ecu be bad or maybe something else?
talked w/ a buddy on mines and he thinks the fuel pump relay might be stuck open and giving the fuel pump constant power..is there a way to test the relay out to see if it's still good or not?
well i tried switching relays and it still does the same thing. but i do notice sometimes if i turn the key to on, about 10 sec later the fuel pump will kick in and start running. and last but not least i don't know why sometimes when i close (have to slam it to lock) the hood while the car is running, the car will just die for no reason....??
oh yeah almost forgot, i unplugged the iacv while the car is running and there's no sudden changes on idle. why is that? btw just installed a new/used iacv a couple of days ago to.
