Complete new engine rebuild. Intermittent engine starting problems. after driving over 30 minutes and turn off, it acts like dead battery for 15 minutes or more then starts right up.

sounds like heat is affecting something. you might have to double check that your harness connectors are properly seated and that all grounds are connected and tight. check your battery terminals as well they might need tightening or replacement.

PASSLOCK, check to see if there is a little red lock symbol on your dash when you are unable to start it.

MOVED this from the H3 FAQ section where it tells EVERYBODY "Do not post in this section." Just because you thought up some question does NOT make it an FAQ.

All H3 questions belong in the................................ H3 Section.

Welcome to HF.
