93 Sierra 1500 "No Fire" Please HelpBearcs 12-27-2005, 12:47 AM 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 GMMerlin 12-27-2005, 06:23 AM 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? zirb 12-27-2005, 09:08 AM 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 Bearcs 12-27-2005, 10:09 AM Thank You, I am going to try all of this out this morning and I will let you know. horse482 12-29-2005, 01:50 PM These trucks are known for having module problems, you can take the module out and any parts store should be able to test it.
