93 ranger fuel injector problem

[slick7623]

I did a cab switch on my 93 ranger , after putting it back together it won't start. Fuel pump turns on , fuel pressure good , runs when I spray starting fluid in the intake manifold . I think it has something to do with the wiring of the fuel injectors ?

To test your theory, get a set of noid lights. They are relatively cheap.
You should have 12v on the red wire with the IGN on but the other wire, Tan or White, is a ground controlled by the computer. By the way, the computer is bolted into the cab from the engine bay side on the left. If you swapped cabs but did not keep the original computer then you may have gotten a Federal emissions computer mixed up with a California emmisions one.

Ya I kept the original computer I started with. I tested the injectors with a noid light, nothin. Replaced both fuel pump relay and the eec power relay.
