Default Hard Start only when warm H2 2003
Anyone,

My 2003 H2 is hard starting when warm. Only warm everyday. Dealer hooked up computer and said it was a pluged converter, and the scanner showed low battery voltage. Fixed converters and replaced battery yesterday. Today replaced the fuel pump and sender before I return to the dealer. Drove 30 minutes, went to restart-same problem, hard start. The hard start continues to get worse.

I do hear a little air hiss, that started right before the hard start issue. That's what made me think that it possibly was the converter. "Sounds like the air cleaner is off when I hit the throttle". Does a leaky intake gasket cause hard start warm but not cold?

Any suggestions?
