Having a starting problem

[dtkarst]

Ive been driving my C20 lately and took it out for a spin last night to see how my lights and stuff all work and when i got back i parked it for a few minutes then tried to start it again and now the only way it will stay running is if i hold the key in the start position and leave the starter spinning. As soon as I let off the ignition it dies. Anyone ever experience this issue? Cant move it much when i have to hold the key in the start position for it to run,

Are you getting power to the coil with the key in the "on" position? Sounds like you might have popped a fusible link or a ballast resistor, assipumng these trucks have either (I'm speaking from General ignition system knowledge, and not specifically about these trucks.)

Well it's got a brand new hei distributor and a new ignition. It'll run as long as I hold the key all the way over

you need a new ignition switch

That was my guess after checking things over..if only parts were meant to last.

That additional information might have helped...

I'd check the wiring too.
