Trouble with hot starting

[kracken]

First, I am not a mechanic.

I have a 1990 Bronco with a 5.0L engine. It has Fuel injectors.

When I start my truck when it is cold, it does fine. Once it gets up to normal operating temperature and I try to restart it, it sounds like the battery is going dead. When it cools off, it starts normally again.

I have listened to many people I know and have changed my starter, battery, positive and negative battery cables, and even my alternator. When I changed my battery, it worked normal for about two weeks then back to the same thing. The identical results were found when changing my alternator.

Any more ideas?

I'd say something is drawing the batt down...

Do you have anything plugged in like a radar detector? Is the light switch working in the glove box? what about that light in the back cargo area, is it off?

I know simple stuff but sometimes thats where the problems are.

Yeah, that could be.

Take a look at all of your connections, make sure they are clean and tight, not just from the battery to the starter relay, but from the relay to the starter, and the ground to the block.

How are you at troubleshooting with a volt meter? I'd start with measuring the voltage at the battery when kit will start and then measure it at the same point when it will not. Make a good clean spot on the engine block to measure between it and the battery positive, also check at the out put of the solenoid to the starter under both conditions. Report back what the results are. We can't be there to look over your shoulder, so at least keep us informed.

Good luck,

I did some playing with it this afternoon and it was an easy fix. I relocated my ground from the negative battery cable to another spot on the engine block and it works fine for now. Guess it was a bad ground.

Good, that's where I was going with the voltage checks. I figured it was a grounding issue. Bad grounds cause a lot of crazy problems.

Yahoo! I love it when a plan comes together /emoticons/[email protected] 2x" width="20" height="20" />

Thanks for posting your results. That's how we all learn from one another.
