crazy battery

Unread post by dalan68 » Thu Mar 07, 2013 3:52 pm

Won't start acts like dead battery.
If I wait an hour or two it starts. When I shut it off, it won't start unless I wait.
I am thankful for any help.

Could be a security issue, like a faulty Passlock sensor. You could also possibly have a bad or loose connection at the battery, starter, or ignition component/switch and you're just getting lucky coming back after a while and having it start. Your best bet would be to get the truck scanned to see if there any trouble codes stored in any of the modules on board. You may have theft deterrent codes, or other issues.

Where is the fuel pressure regulator on a 4300 2003 S10?

2003 Chevy S-10 Stall out

Unread post by Sling » Tue May 02, 2017 10:38 am

I have a 2003 Chevy S-10. My problem is when I turn on the air conditioner it shuts the truck off. If I turn it on while I'm driving it will stay on but once I'm in idle it shuts off. Please help
Thanks.

it's possible that the compressor is putting too much of a load on your engine. It could be there is too much drag on the compressor or the idle control is bumping the idle up high enough or the throttle body could be coked up and the engine is stalling before the computer can bump the idle up.

hold the idle up to about 1500 rpm and then turn on the ac. how low does the rpm drop? or does it still kill the engine? If it still kills the engine there is probably to much drag from the compressor.
