350 tpi harness issues
Ok I have a 1986 iroc with a 010 casting 350 4-bolt and I decided to put the motor in a 1962 ****** 1 ton pickup. I've had to make a intake elbow simalir to the LT1, I also made a cross member running under the engine from 1/4 wall 3'' square tubing, solid motor mounts, lower raditor support cross member, steering column, rear frame (bumper) from 3\8 x 4 stock, spring mounts. I am going to run a 3\4 ton chevy setup np203 awd tcase,
Well any how Im having a problem with the fuel injectors I cannot get them to fire, so far the mass air system seems to be functioning properly aswell as the fuel pump prime and the only code i get is a code 12 .im not sure what else to do.. any advice

grab a test light and a friend. Disconnect one of the Fuel Injectors and hook up in-line with the injector wiring. Now have someone turn the key to turn on the car. BE SURE TO PULL OUT THE FUEL PUMP FUSE SO THAT THE ENGINE WONT START. Now once the key is turned, the test light should light up in a pulsing manner. If it does, then its all good. I dont know if the injectors should be hooked up in sequence though. But if they are hooked up in sequence, then lay out the wires over the valve covers and they should fall into place (due to aging and time, the wires should be bending towards its proper injector).

Good work through here for fault finding

Have you checked the resistance of the injectors? One bad injector will take the whole bank out

Re: 350 tpi harness issues
A bad ignition module would prevent the injectors from working, most auto parts stores can test them.
