I bought an 86 Trans Am that had been a TPI car that somebody had changed to carb. I have installed my TPI engine, reconnected all the engine wiring, reinstalled the missing fuel pump but I don't seem to be gettinganything out of the ecm. The ecm is the same one that came with the car, I have not found any cut wires, the fuse for the ecm/fuel pump is good. The fuel pump will not prime and the fuel pump relay will not energize. I checked all the fuses in the car, all of them were good, however I noticed that there was no "CRANK" fuse installed. I cannot find any info on that fuse or if it needs to have one. Every thing else seems to work, the car turns over fine, I don't know if I have missed anything else that might have been cut or bypassed.
