No. I had heard of an LED trick for my VW Vanagon, but can find no reference to it. It used an LED and a drop-down resistor. The reason an LED is used over a lightbulb is that an LED reaches full brightness in less than 1/10th of a second. The light bulb takes a full second or more. You will no doubt see the pulse!
I replaced the fuel pump relay. No difference. One more thing off my list.
Is it possible for the ICM to see a high enough RPM to hand off to the PCM without the fuel injectors firing?

My fuel pump sounds exacly like yours...my exhaust does not. Oh, and our grass is brown right now, not green!
I'll be calling around tomorrow for an ICM. I have the Delco coils. It looks like the ICM is the same for a Delco or Magnavox coil pack?
