Re: ignition module , where is it?

Take the dizzy cap off and its up under the rotor button you should see it.

Yep:

"If the chip is installed correctly, and you definitely have both spark and fuel pressure, your ignition module is dead. A bad ignition module won't generate a reference pulse preventing the injectors from firing. Part number is 1048-2827 (located under your distributor cap, BTW). Some auto chain stores can test to confirm it it's good or bad."

If you have a store that can test it for you, be sure to have them test it a three of four times to heat it up. I have seen modules that would pass the first test only to fail after it was tested again.

And if you do swap it out don't forget the heat transfer stuff underneath.

Actually it's heat transfer compound or heat-sink compound. Dielectric grease is a lube that conducts electricity. Used, for example, on sparkplugs to make it easier to install and remove the wire/boot. A tiny tube of it will (or should) come with a new module. Both should also be available at your friendly parts store.

Huh, I always thought it was for the mounting surfaces of modules also. I guess you learn something everyday.

One thing thou, dielectric is non-conductive. If it were, then there would be conductivity between the posts of a module, which would be bad.
