2003 Chevrolet S-10 Repair Question
03 Chevy s-10 stalls out
Answer
Do some testing, yourself. If the starter won't even crank, check the starter circuit. The purple wire at the starter solenoid S terminal should be hot with the key in the crank position. If that wire isn't hot, backtrack the circuit.
Intermittent issues can be hard to track. You have to test when the problem is ongoing. I can only suggest what to test, you have to do the testing.
When it stalls, if it cranks good but won't start. Have a helper crank it while you check for spark at the spark plugs. If you have spark everywhere use a gage and check fuel pressure. You need to be carful about gas spraying on a hot engine.
All the fuel stuff has been tested. I'm at the end of the rope. I've gotten all kinds of diagnosis and its been tough to isolate the problem. Right now, we are checking the crank shaft sensor, and harmonic balancer to see if that will help, replace the relay swith already, fuses were checked. It's been more than frustrating, especially when you change a part she'll run good then you end up stalling out, and back to square one.
The starter motor circuit isn't that hard to check. I understand your frustration. Intermittent issues are a pain, you have to test when the problem is ongoing, to see if you can track the issue.
