Hey guys, I've been noticing with summer rolling around, that after a long drive and my engine is nice and hot (not overheating) that when I stop and go to start it back up it's really reall slow to crank over almost like my battery is dead. I haven't done any diagnosing yet just wondering if y'all might have a quick fix for it. The only thing I could think of was replacing the battery wire to the starter. Although it doesn't look bad. I also know that as temp rises, so does resistance, and my battery wire is pretty close to my header. I was thinking of replacing it and wrapping it with some sort of insulation? Any help is appreciated.

Thats a good start. Sounds like the starter is getting heat soaked. It also never hurts to pull the starter and wire wheel the block surface it mounts to. That is the ground for it.

I had simialr issues with my 79 after I did the TBI swap. I replaced the starter and cable with other used ones I had and it corrected the problem.
Do you have headers?

get a heat wrap for the starter.the header heats up the solenoid and starter and causes it to crank slow.mine does the same thing.i will either be puting in a heat shield or a starter heat wrap to keep the heat away.its much worse with headers.

Hi, I was parking my 1989 blazer TBI 5.7 while it died. No way to start it again, I turned the key and nothing happened, like disconnected battery condition. headlights and interior dome light works, while hazard, back glass, bottom interior lights and every ignition controlled-equipement don't work.
Battery is good. What happened? is there any solenoid/resistance/wire to check? if yes, how to find it? where is it?
thanks so much

Probably lost one of the fusible links that power the truck. They hook up to the battery at the starter solenoid.
They look like regular wire, but they act as a fuse. They are a couple of sizes smaller than the wire they feed, and most of the time have fireproof insulation.
If one of them is bad, be sure to replace it with the same size wire, or buy one of those fuse kits that some people have replaced them with.
Not sure what size fuse it takes, but someone here will know.
If not that, then it might be the ignition switch or linkage.

I went through this problem a while back..
I tried everything from a new starter. to multiple batteries. the "ford" solenoid switch thing..
then I replaced the positive battery cable AGAIN, with a 0gauge wire. and.. it never happened again..
I would bet you $20 its your cable

thats a possibility as well.ive had the cable rot from the inside with no indication on the out side that could be seen.if the cable hasnt been changed or looks old or worn or melted in any way,it may be time to change cables as well.check all the grounds and ground strapsas well as the 2 wires coming off the firewall to the starter.one is a wire to power the interior which i believe is a purple pink color and the other is yellow on mine that goes to the start terminal on the starter to power the solenoid.there are many factors that can lead to a non start issue.the starter could simply just die showing no indication that it is on its way out as well.ive had that happen a coulple times.I went through this problem a while back..

Sounds like the same problem I had last summer, I replaced the starter and made me a little heat shield for the solenoid.....it was a cut up beer can

I found the problem: it was the wire that carries the power to the cabin, it's bolt on the firewall behind the big red wire. It was old and not completely interrupted, but the current was not enough.
Hard to find problem!
