: Starting Issue - Starts Great . . . Sometimes

Okay . . . .

Since you all have been such an awesome resource (thank you all again for that!), I wanted to see if I could try to stump you again. Sorry for the long description, but I want to give as much info. as possible.

My '95 K2500 Sub is a beast - generally starts and runs great. There is a quirk with the starting system, however. I know the starter works (at least most of the time) because the thing usually cranks like a beast.

Sometimes, however, if the truck has been run for a while (like out doing errands from place-to-place), or if I run it for 25 minutes and then it sits in my garage at work for a several hours, when I turn the key to start it it just clicks once and that's it. The batteries are fine. The connections appear to be fine. Here's the odd part. If I let the truck sit for a few more hours (so it cools down), it fires up like new.

When I purchased the truck the guy said he had replaced the starter a few times only to find out that the issue was with the battery cables . . . not the starter. The battery cables look fine. I'm thinking it's the solenoid, but don't really know.

Any thoughts? And thanks for sharing your time and expertise!

Grounds or main battery terminal connections, remove GMs battery side post screws and replace with stud/nuts, pics in FAQ

I have had similar issues caused by a bad lead wire to the starter (the small one - pink or purple). I fixed it by cutting off the old end and soldering on a new one....
