Vehicle starts, then won't start

When you say, you get nothing. You mean no electricals? Headlights won't work, interior lites won't work? Use a voltage tester at the fuse block, anything?

If your just talking about the starter, check the starter circuit. Also, your security system could cause a problem? Any applicable trouble codes? Some of the national brand autostores used to check codes for free. You can check trouble codes yourself, at the least, you need an obd2 code reader. I'd get one that would check generic as well as manufacturer specific codes.

Intermittent issues can be a pain to track. If there is a bulge in the battery, that doesn't sound good. I can give you a wiring diagram on your starter circuit, if that will help?

If you have any questions about the diagram, holler.
