Question Help diagnosing electrical problem?

Truck has been back on the road for a few weeks. Basically everything is new - motor, trans, complete wiring harness, starter, alternator, battery, etc. Swapped in a used automatic column with tilt, to replace the old column I had when I had the manual trans...

Go to start it yesterday, and nothing. Not even a blip from the starter. Try it again, and it fires right up.

I am in a hurry for work, so I don't let it warm up as long as I should. Make it to the end of the street, and it dies. Go to restart, and nothing again. Dead as a doornail. Headlights work, but nothing that is "switched" power works. Won't start in Park or Neutral. Nothing at all. Get my wife to steer as I push it back into the driveway, and as I hit the end of the driveway it magically springs back to life. Power returns to AC. She hits the key and it fires right up!

I have checked all wires and cables, and everything is tight. I am thinking that the ignition switch in my used, eBay-special tilt column is going bad. Sound like a reasonable thought?

Re: Help diagnosing electrical problem?

Years ago in my cutlass I had a similar situation but with no restart. It end up being a bad starter solenoid or a burnt wire at the solenoid. I can't remember which.

Re: Help diagnosing electrical problem?

could be a bad or misadjusted ignition switch. If you replace it, use a Delco part.

1980 - the one in my signature. I need to take "after" pictures, now that I have completed a ton of work on it...
