HEI Guide On-line?

[EricVonHa]

Hi everyone... I'm looking for a guide to HEI troubleshooting on-line.

So far I've replace the ignition module. The coil checks out ok. And, I've replaced the four pin external module also from a known running Vette.

Any ideas of where to find good HEI info? I've done a search and just haven't hit payday yet!

Thanks CC. The first link was great. #2 and #3 were previously found through Google. And #4 is a dud.

The problem (as I see it) is that the ECM is not seeing the reference signal being fed back upon a "crank" situation because the ECM is not firing the injectors.

I get a good solid 12vdc to the coil also.
