hey, i've finished hooking everything up after i dropped my newly rebuilt 7mgte back into my supra and i turned it over the other day, it fired, it started and it ran for about 5 seconds before dying. i tried starting it 4 more times with the identical results so i checked my injectors with a noid light (or however you spell that) and when i cranked it, the light didnt turn on so according to that, my injectors aren't getting a pulse signal. however fuel MUST be getting to the cylinders SOMEHOW since it starts and runs for right around 5 seconds and then dies. could the cold start injector supply enough fuel to support 5 seconds of run time? and any ideas as to why my injectors arent getting a pulse signal? thanks in advance!!! i'd love any help i can get!!
