So trying to get wood cut today for the storm rolling through on Friday my saw stopped working. But thats minor i suppose. My problem is that my lovely blue bomb has developed an intermittent no start. Its done it a few times before to me. Usually cycling the key gets it going. Yesterday it happened after it sat for a few hours while i was at a fire department training. Cycled they key about 10 times and she fired up. Engine was cold. Today it happened twice. The engine was warm. Today i cycled the key a few times again and no go. Poured some fuel into the throttle body and it took a few times. My fuel filter is only a couple months old. Every other time my fuel filter clogs i get issues while driving. Never a no start. What could be the issue? As im sure some of you know my diagnostic skills are lacking so im turning to my truck bros for help.thanks

Get someone to crank it over and feel and listen for the fuel pump. If the pump is weak and the voltage is down it may just not want to work. If you have an Amp clamp check for excessive current draw on the fuel pump wiring. That will tell you is tailing.

You could get a remote start switch to hook between the solenoid on the starter (signal post not starter power) and the battery. After the autozone model lasting only 10 turn overs, next time I'll just run a wire down there and short it to the positive terminal on the battery (key off). Just bump it and see if it messes up. If it doesn't, then it's likely your ignition switch. If it does, it's from starter to battery or ground.

Pull ignition power from the distributor so it won't start.

The starter works perfectly. Motor turns strong. Im gonna test the fuel pump wires for amperage when i get home. Had a buddy crank it over while i watched under the hood. My fan clutch is a little worn but thats about it under there.

What should the amps be for the pump? And i should test closest to the pump correct.

I can’t answer that with any kind of certainty. I can only say that 15+ amps would raise a flag with me. @1987 GMC Jimmy or @chengny may know off the top of their heads though.
