93 Sierra 1500 "No Fire" Please Help

[Bearcs]

I was driving two days ago and truck just died right in its tracts. It would turn over but wouldn't start. I immediately assumed Fuel Pump. I checked the pump and its running. I replaced the fuel filter and thought that would fix it but it didn't. Still just turns over and no start.

Next I changed the coil out and no change. I looked at the rotor and the distributor cap and they look fine. I have pulled two spark plugs and neither one show that they are getting any fire. I am really stumped here as to what to look at next. Any suggestions? Thanks

Do you have power to the coil?
Do you have a good coil ground?
Do you have spark from the coil wire?
Do you have a trigger signal from the module?

Do what merlin said with the coil wire. My burb did that and it was the coil wire. Got to buy one at dealer,dealer only part. $28.00

These trucks are known for having module problems, you can take the module out and any parts store should be able to test it.

Thanks for everyones help! It was the ignition control module inside the distributor cap.
