Ok folks, here's the problem. We've got a 1986 2wd Comanche with a rebuilt 2.5L V4 and a 5 speed manual. We have replaced just about everything you can replace on this thing and it will start (turn over and crank) but will not run. The problem seems to be electrical/fuel delivery related but we're not sure. New fuel pump, new fuel tank and everything else. With a noid light attached to the TBI connector when you go to crank the engine the light on the noid gets bright for a moment then goes dim. We were told that once the engine cranks the niod light should flash. It's doesn't. It just goes dim and we have no fuel pressure in the TBI. The ECM has been replaced along with every other electrical component associated with the fuel delivery system, when we bypass the fuel pump relay we get good fuel pressure but when we plug the relay back in - nothing. We've replaced the relay three times and still the same issue. What I need to know is if this is a wiring harness problem or a ground problem. Any additional info you might need please ask but we're not sure where to go from here. Any "actual" help would be greatly appreciated!
