So i had to recently install a new fuel pump in my car. installed the fuel pump and went to start my car and it would not start. checked fuses everything is fine. so decided to replace fuel relay because i wasnt getting any power to my harness that plugs into the fuel pump. replaced relay still doesnt start. getting 0 fuel pressure. so i figured what the hell and pluged my computer in to see if i had any check engine codes even though it wasnt displayed. and im not getting a response from my ecu??? welp there is my problem but now im stumped??? i unplugged my ecu for an hour just to see if maybe that would reset it and i also unplugged the big ecu thing (dont know technical term for it) in the engine bay fuse box. but still nothing. i dono if im missing something or if for some reason my ecu went out?? (hope not) any suggestions on what i can try or look for? thanks for any feed back
