h1 stalling
1995 h1 stalls out. i've replaced the lift pump, all fluids, fuel filter, oil pressure switch, and oil pressure sensor. still stalls out and is hard to start back up. ran new gas in it, the lift pump does not show any power when i hook up a tester. any help would be great.

RE: h1 stalling
your hummer being a 95 has a non turbo engine. the injection pump is a mechanical one with no electronics. if it is stalling, it is because of a fuel issue or you are losing the power to you shut off solenoid on the top of the injection pump. how often does it stall? do you have to prime the fuel filter to get it started?
