16v blue top no injector pulse
Posted: Fri Mar 24, 2017 8:40 pm
Hey guys,
So i have a rebuilt bluetop that i just dropped in, it cranks fine but i couldn't get it to start. Sometimes it sounds like its about to turn over but then it just keeps cranking. I have both spark and fuel. Fuel pressure is 35psi at the rail. I measured the voltage at the injector connectors with the key on and i get 12v on one side and about 100mv on the other, which there should be 12v on both sides right? So i checked the manual and it says to check the ecu for 12v on 2 terminals:

Im getting 100mv at those terminals so i follow the flow chart and inspect my fuses and ignition switch and they all are fine. my grounds seem to be connected too.
would the problem be my ecu or is there something else that i could try and do? Any help would be greatly appreciated.
