Problems with my H3 2008 starting
It will try to start but its is as if its not getting any gas, so then I turn it off wait a minute and start it again an this time it will start but somtimes reves it engine very loud
I am having the same problem with my H3 2006 model. But I wait 30 seconds instead of the 1 minute you described. No mechanic is able to solve this problem so far. Any help from fellow board members? Thanks,
change the fuel pressure pump on ur hummer. http://hummer-h3.org/2006-photos/
Thanks. The problem was fixed last month. It was actually the engine oil PUMP.
FOR OUR 2006 H3 IT WAS THE IGNITION SWITCH. GM PUT OUT A HELP TIP FOR THERE TECHS AND ITS THE FIRST ITEM ON THE LIST TO CHECK.
Fuel pump relay # 66 in the fuse panel pull it out replace it your hummer should fire right away.
