hi i just completed a motor swap from a 96 blazer to 96 jimmy. 4.3 vortex with w for vin code. now i can't get the motor to start. I checked for spark thats good. checked for fuel at the schrader valve thats good. no check engine light. so no codes. ran before i took out of blazer. there is one wire not shure it is in the right spot. it comes off the wire harness going to the intake for the injectors. it is two wires into one eye termanal .i think it goes to the alternator but not shure. if you can help would be greatful. thanks tom

 

What are the wire colors? If they are black, they go to the back of the passenger side cylinder head.
