My truck just lost spark yesterday. I checked the ground, voltage, plugs and wires, coild, resistance between the two wires for the distributor and think that it is the ignitor assesembly. Which is the device that gets 12vdc and is the mounting location for the coil. Now if I'm reading this right which I really hope I am then instead of paying the 270.00 retail price for a new one I can use a chevy part? Thanks ahead of time!

thats correct my friend...

I know when my truck didn't want to start. My problems was related to the ignition switch and had nothing to do with what was under the hood. Your problem may lie their.
Just putting that out their.

good luck.

The 12v goes to the "b" and splits to the positive side of the coil? And the same thing with the "c". I have the correct part form a chevy but just not sure about those two wires. thanks.

the "b" means battery and the "c" means chassis (ground)

Ok, so my truck cranks over just fine but with no spark. I'm pretty sure I toasted my coil last night hooking it up to 12v on the positive and to a ground! It was hot and now has no primary continuity....So I have a gm hdi ignition module. The distributor is hooked up to one side and I hooked the other to a good ground and a 12v. I know that this is a simple process but I don't understand how it works? Should I tie the ground from the coil (a new one) to the ground coming off of the ignition module? Also can I splice the 12v going in to the ignition module with the 12v into the coil? It's a simple system but I just can't get it?? thanks.

yep that would work to take power and ground from the coil....

have any pics or maybe a little scheamatic? because the service manual says to NOT route the coil directly to ground?
