Well I have a few things wrong with my car ever since I got it back from being stolen by the shop. I have replaced the cabin harness because they clipped my ecu plugs. I have done the mpfi swap but my fuel pump does not prime, I took it out and tested it by running a wire straight to the battery. Also the key in the 1st position nothing happens on dash, 2nd position it does have the lights and radio does come on.

 

make sure that your ground wires at the thermostat housing are connected, clean and secure

 

Main relay or ignition switch...
