Hi All,

I just got back from a 10 day trip, car sat in my driveway - I went to start it and all went fine, car fired right up. I walked away for 2 minutes to let it warm up, and it started to idle low - then just burrrr died out. Couldnt start it again! I let it sit for an hour and it started back up, but once I touched the gas it died again. I fully charged the battery and not wont start at all. Anyone have this issue, seems weird to me - maybe dirty fuel filter or car is not getting spark?

That could be a number of things...Could be a bad injector or a bad fuel pump...

No offence, but did you check fuel level?

If okay, then I suspect a bad pump, or even a fuel tank sensor!
