I put the motor into my car and stuff and i did the wiring to change from the dpfi to the mpfi according to what i have seen on this site. The car turns over but it is not getting any gas to start. i pulled off the fuel liine that goes to the fuel pressure regulator and no gas flows through also my dash light don't come on for some reason just the engine light can anyone help me out with this one i am so close to getting the car running.

 

have u double check ur wiring and for the gas it maybe the fuel pump does it turn on when u turn thekey switch is on.

 

yeah the fuel pump makes noise and the wiring seems to be right i checked it more than a couple times. Now what im trying to do is to use my old dpfi harness and wire in the injectors and stuff and imma see if that works.

 

did you hook up the ecu grounds at the thermostat housing?

 

okay so i said screw it and i took of the ls wiring harness of the motor and i put the dx wiring harness in then i ran all the wires and stuff. The car finally starts. Now it runs like **** though when you give it gas it doesn;t do anything unless you hold it for a while then itll start to rev up slowly. Anyone have any ideas.
