Skip White on Fleabay.

I would try to change your ignition control module first. I've had them go out before on more than one occasion. $15 at O'riley's.

And if it's your ignition module don't forget to put a healthy dose of dielectric grease under it when you put the new module in.......should be included with your new module.

First check to make sure wire connector didn't pop off distributer terminal on cap then check module. This happened to my dad last summer.

This sounds like when my Chevelle threw the timing chain. Check that out as well.

Take out your ignition control module and run down to O'reilly's, or the equivalent and they can test it. Also, O'reilly's usually only stocks the Accel control module, which is like 40-50 bucks, so you may want to order one because the stock replacement is like $15, or so. Just depends on how fast you need your truck.

I just ordered the new distributor from Skip White's Ebay store and for $50.00 shipped, it's a pretty darn nice dist.

Also, depending on your engine setup, you may want to look at a cab/cowl seal. I just went through what happened to you and after opening my dist cap, I could tell that during rainy days that water was coming off my cowl and getting into my distributor, severely shortening the life of it.

take cap off crank engine see if rotor is spinning. I think you lost a timing chain son. If your lucky it have have burnt a connection where the coil terminals meet the wires,

Re: did not see this comin
 

If you lost a timing chain it would make a different "sound" when starting. It would be more of a fast whirrr instead of the usual "heavy grunt." If the timing chain is busted only the crank/pistons are spinning. I've popped a couple on Toyota 22R engines and they make a much different sound when turning over, in addition to the sick feeling that you've just destroyed the pistons/valves. Luckily on old chevy motors, they're not zero tolerance and you can just put a new chain on :D Is your motor a straight 6 or v-8?

Sounds like an electrical issue. My vote is wiring and/or control module. Check your fuses too!!!! Are you using a 12V wire to the HEI or did you use the original wire that went to the points coil? That wire only has 8V going to it.

Re: did not see this comin
 

Check for breaks in the two wires going from the base to the coil.If there`s a break it can cause the module and the pickup to fry.
