well, confirm the fuel with a fuel pressure gauge, or pull the line off and turn the key on and see if fuel comes out. then u can also see if the injectors are firing.

hey today i spend the whole day finishing the wiring there is fuel going in but the injectors are not firing because there is no ground getting to it i connect a ground cable directly from injector one cable to the batery and the motor started right up but after that i would not start again any ideas what could be happening

yeah the ecu cuts off the motor at 2k if its not getting a maf signal, check into that first
