With much help from folks on this forum, I managed to complete installation on my FAST E6 ignition yesterday. This is wired in conjunction with my Performance Distributors (DUI) distributor and EZ-EFI injection. I've checked and rechecked my wiring on all components, and I've had FAST and DUI confirm my wiring, so I know it is correct. I fired it up and went for a test drive, yesterday and, while it seemed to be running smoothly, it was way down on power. I drove for quite a few miles after warming up. I returned home and rechecked my plug wiring to see if I'd crossed anything up, and all was correct. I went back out for another drive and, after a few miles, it backfired a couple times and then died. After that, it would not fire again. I put my noid light on an injector and found that there was no signal to the injector. I rechecked the green wire from the E6 to the ECU and found no issues with the connection. With key on, my ECU did not have the blue light lit anymore. I checked the power connection (which I'd never changed from its original configuration) and found no issues. I called FAST, and the fellow had me check my IRM noise reading; it was 77! He surmised that this was the problem. At this point, I'm not sure how I can route the wiring significantly differently to reduce interference. Any ideas, guys?
