Would this be an ignition switch problem?

Yesterday morning I started my truck and went back inside to finish up getting ready for work.It was idling for about 5 minutes put it in reverse and it died.I restarted drove to work no problems.This morning started it drove it to work noticed that my dome light didn't come on like it usually does when I turn it off it wouldn't restart for the first two times I turned the key switch then my interior and dash lights came on and it fired right up.I am not sure what else it could be besides my ignition switch.I would appreciate if you guys think it could be any thing else.It is 02 silverado with close to 258,000 miles on it.

Re: Would this be an ignition switch problem?

I had a similar issue on my 2005 Silverado. It was the module in the door latch, that goes to security/body model. It wouldn't recognize the Dorr was closed and caused battery to run down or wouldn't allow it to start

Re: Would this be an ignition switch problem?

Thanks I will have to check that out.My battery isn't running down but I do have the security light.I guess there is also a relay for the starter that can cause the problem I'm having.

Re: Would this be an ignition switch problem?

Doesn't crank or doesn't start?

My truck is cranky about cranking. I narrowed it down to the connection from the starter relay to the Crank terminal on the starter. I think it may be the fuse/relay block but I haven't torn into it yet.

It doesn't crank.I had no problems this morning.I will probably check and clean all of my grounds this weekend.That is the cheapest easiest thing to do first.If it still continues I will swap around the relays.

Swap the DRL and Starter relay. It takes a couple seconds.

Daytime Running Lights. Any of the ISO 280 relays in the box are good candidates to play swaptronics with.

Unfortunately my truck is doing this now as well.They say the grounds can be an issue on these trucks.Some say the problem is in the starter wearing out.My engine just barely turns over after driving a long distance when I try to restart it.Let it cool down and fires right up.Also on the right side of the engine is a fuel pressure regulator you can unplug the vacuum line going to it if has fuel dripping out it's bad.Mine has no fuel dripping out.

Check the main ground connections but slow hot crank really sounds like a starter problem.

Re: Would this be an ignition switch problem?

Took the starter off and took to the local business that rebuilds them.He said let's do a load test on the battery first.I think to myself ok battery is not that old but this guy knows more than I do.I have a bad battery.He said that's what's causing the slow crank.Im not for sure if that could have caused my truck to randomly shut off I forgot to ask him about that.

Re: Would this be an ignition switch problem?

to me it sounds like a bad battery...or loose terminals. if that battery is over 2 years old (which is usually right after the warranty) then I wouldn't trust it anyways
