1996 S-10 Charging/Cranking Problem

I have a 1996 S-10 with a 4.3. Recently I had my truck just cut off while driving. Found the battery dead and the Alternator not charging. Changed the battery and corrected the Atlernator, but now at times when I go to start the truck it cranks over but won't start until i hit the gas. The battery gauges shows a discharge and the engine stalls out. I can wait a couple of minutes and then restart it with no problems?

Ever changed the fuel filter?

Yes the fuel filter has been changed on a regular basis.

check the battery voltage when not running and when it is running.

Report back with your findings here.

Voltage is 11.8 engine off and 13.8 engine running. I can start 3 or 4 times in a row before it starts acting up.

Your battery voltage is low when the engine is turned off.

It should be between 12.6-13.4 volts.

Remove the battery from the vehicle and charge it with an automotic battery charger and charge it completely.

Ok I will try this again, Thanks

I went and recharged the battery like recommended. Voltage at the battery engine off was 12.2 and with engine running 14.3. However when I go to start the vehicle it turns slow or strained as if it has a large load or it's cold outside. After several more attempts it will just spin over until the gas pedal is pressed, but once you let off it is stalls out, if you feather it until the battery gauge starts to show a positive charge then it will stay running. Any other ideas?

How did you charge it?

12v charger at 2amp for a little over 3hrs

it was out of the vehicle and i installed battery studs in the side post.

Was it an automatic charger?

Yes it was. It has an LED that said the battery was completely charged

Almost sound like you have a dead short somewhere.

How did you fix the alternator, did you replace it?

Yes I did replace the alternator and the battery was replaced 5 months ago.

Ok, well, I would check the fuel pressure.

Sounds like your pump is about shot or you have to do a tuneup.

Tested the fuel PSI and it was good. I went ahead and done a complete tune-up. Went to start the truck and the battery was dead. I had charged the battery yesterday. I recharged the battey and completed a draw test on the starter. Replaced the starter and comfirmed that the battery was fully charged. The battery had 12.8v with the engine off and 14.4v with engine running. I did place the DVM leads back on the battery and noticed that my voltage was dropping a 10th of a volt every 2 mins or so. Completed another starter draw test and noticed no draw. Any ideas?

Any one have any ideas? Vacation is almost over and it will be time to return to work.
