so after i let the car sit over night it doesnt want to get fuel..ive checked evything and replaced some of it but to no avail..so i thnink i narrowed it down to a fried ecu,and here is why injector wires are getiing 12v,injectors work when hooked up to battery/ground. maybe the ecu isnt sending the ground to make the injectors fire?? its my ast option any suggestions?

 

It definitely could be your ground from the ECU. The injectors rely on the ground coming from the ECU and terminating in a gang ground near the rear of the engine. IIRC its pin 3A and 3G that should have continuity with ground. I had the same problem. The ground were not there and the injectors wouldnt fire.

 

eyy! thats the same problem as mine! The rear primary doesnt go to ground so now i run both primarys on the same pin (yeah not very wise )

 

checked my 3A and 3G, they are connected to ground

 

yea both injectors fire fine,just not reaching the housing wierdest thing ever
