My Hummer H2 2003 model had a problem starting when its warm. Like when I start it in the morning, its normal, but after driving it for a few minutes and the engine is warm, I had difficulty starting


I had this same problem with my 2003 H2, my mechanic found that the fuel diaphragm was cracked and this was allowing my truck to flood. If it was a cold start, the extra fuel would evaporate and it would start fine. It actually got to the point where I would stall at a stop light or stop sign at idle. The part was is the neighborhood of $175.00 and about 1 hour of labor to install.

Hummer H2 engine won't turn over, key won't


Dead Battery? Bad starter motor?

Try pushing on the brake and making sure its all the way in park.

Turn the steering wheel back an forth a little to remove the key.

None of those work, Call triple A, find a shop.

I can't solve the problem but was hoping you found the answer. I have a 2003 Hummer H2 and I am having the same problems if started in park or Neutral it will idle fine but if I put it in drive or reverse it will not idle

Did you find the solution and if so could you email me the fix.
