Question about 1997 GMC Sierra
I really dont think its the ignition module.Those are a little expensive so i wouldnt buy one until you sure thats the problem.I would turn the key to the on position and listen for the fuel pump.The pump only runs for about 3-5 secs when you first do it.If you dont hear anything thats the ploblem.If you can hear the pump come on try to use starting fluid to get it started.If it starts and runs fine then the fuel pump doesnt put out enough pressure to start the truck and need to be replaced.If that doesn t work take a spark plug out of the motor and plug it back into the wire.When you try to start the truck it should make a bright blue spark.If the spark is not bright and fast it could be many things like that plug or that wire all the plugs and wires or the distibutor cap or the rotor.It could also be the coil.If you have the money you should replace all of that stuff.If your on a budget like me I would change the distibutor cap and rotor and see if that help.If the plugs and wires are fairly new change the coil.You should do your plugs and wires after so many mile or time period.Im sure its not the Ignition control module.The guy at the part store always says that might be the problem and ive never bought one yet.My truck has 250,000 miles on it and still going.

Check all your fuses and relays as well as all your vacuum lines are attached also fuel filter and air cleaner filter check to ensure the fuel is getting to the engine as well as check for spark with someone who knows how most people will help with this by using a Phillips head screwdriver and holding a plug wire away about a 1/2 inch while turning it over check that the wires and coil wires are attached and didn't pop off this is where i would start by breaking down all the obvious possibilities if there is a gas shut off on it pull it to operate the gas again

It's the ignition module in the bottom of the distributor take it and have it tested. It just unbolts from under the cap.
