Q: I have a 2003 Hummer H2 with 63,000 original miles.
Hello, I have a 2003 Hummer H2 with 63,000 original miles. My H2 has been stalling on me while driving on 4 different occasions in the last couple of months. Once the H2 stalls, I crank the engine and it will not start. After waiting about 5, 10, 15, 20 minutes later the Hummer h2 starts with no problem. It feels like the H2 is starving for fuel. The starter and battery are in good working condition. Also my H2 is not giving any check engine codes. Any suggestions? Thanks Based on my research, I'm thinking that It might be fuel filter, fuel pump or cranking position sensor. Thanks FDR (619) 829-1319
