Asked by Jerry Sep 27, 2018 at 01:21 PM about the 1990 GMC Sierra C/K 1500

Question type: Maintenance & Repair

some days it will not start. give it a shot of starter fluid and it usually starts. then
again some days that won't do it. When that happens I found that I was getting
no spark. Once it does start it will start all day without fail. I can hear the pump
working when I turn the key, thinkin I may have 2 different problems. anyone
know what it could be?

I would suspect the ignition module.
