Ok I have checked out everything I can think of . The injectors are getting fuel and 12v, it is firing, the fuel pressure is good. This is on an 87 4runner i bought with a locked up motor. I had it rebuilt and all the fuel injection worked over. It was all pulled out when i bought it so im not positive about all the wiring, one being a brass ring coming out of the big wiring harness, it has 3 red wires crimped onto it??? Please let me know

 

Sounds like something that should go, say, inside the distibutor ??
