After installing injectors, B&M CommandFlo, GS-342 fuel pump, cap and rotor, changing the oil in my JRSC it ran like crap, it would hardly idle. After taking everything off (JRSC and intake manifold included) and not seeing anything out of the ordinary I put it all back on and it ran fine for a day. Then going down the street on Saturday it just quit. There was some smell which I thought was coming from my brakes from not having driven the car in a week but it could have been electrical. I thought I had left a wire too close to the pully/belt or header/exhaust and it melted but after towing it home and inspecting all the wires I could fine nothing wrong. I then thought it was the ignitor so I started the tests in the Helms for the ignitor and coil. It appeared as if the ignitor was bad although there is no real test for the ignitor, just that there is power to it. Anyway, I got another ignitor and put it in and......nothing! I ripped the JRSC and manifold out again thinking that I had pinched the woring harness that runs along the back of the block in-between the JRSC but found nothing out of the ordinary. I disconnected all the wires going to the distributor from it and the ECU and checked than none of them were shorted out and everything checked out, except the main power to the coil showed that it was grounded but I think that was from the ignition switch because when I unplugged it from the driver's shock tower harness, the test light went out.

I have been down for a week now and have had to rent a car and am having to rent it for another week now! I am starting to think that the replacement ignitor I got is bad too because everything else checks out, but no spark, I pull a plug wire and connect it to a spark plug and crank the motor and no spark.

Does ANYONE have ANY advice? I am totally stumped!!!

 

Check all your grounds. ALL of them. The main one to the tranny, the small one to the valve cover, and the ECU grounds that go to the thermostat.

 

Will do. Anyone else?

Thanks,
