Alright so I have been working on my b18c1 rebuild for a couple weeks and I finally got it back in and when I crank I get spark, compression, and fuel to the rail but the injectors won't open and spray fuel in. 12v are present at the injector connectors and the ground on the thermostat housing is on good so what else can it be? I know a bad ecu is possible but I drove the car to the garage im working out of and I did not have any issues for months prior so I have a real hard time believing it can be that. I am hoping someone smarter can maybe think of what the heck is going on. Could any sensors not being hooked up right cause this? Im so frustrated with this. Also its a chipped p28 with a conversion harness that I have been using for months.

Check your ecu and grounds.

Well grounds are all good. I tried another ecu and it still didnt work

are those injectors new or used? Check with different injectors, check your regulator and check your fuel filter and fuel pump again.

Thanks for the suggestions but I got a pulse! The middle plug on the passenger shock tower came unplugged. Fired right up and runs smooth as ever.
