Hello All,

First time posting here. I have an 89 c1500, 5L TBI, 2wd. The engine turns over like a champ but won’t start.

There is no power to the distributor or coil with the key in the ON/start position (measured from the pink wires to ground).

I do measure 12v from the pink injector wires to ground with the key ON.

I also had an incident recently where the truck wouldn’t turn over. The ignition lock cylinder is very worn and before this issue I was able to start it without the key.

Has anyone had an issue like this before? Could it be the ignition switch?

Thank you in advance

Thank you for the feedback.

I found the problem, not what I expected and not something that would occur “naturally”. The previous owner installed a 95 lumbar seat and wired the pneumatic pump into the pink 12v distributor/coil feed. He cut the feed, ran a wire through the firewall under the carpet then back to the distributor. I replaced the lumbar seat with a solid bench which opened the circuit that was scabbed onto the ignition feed.
