Not sure where to post this. Last night I drove about 20 miles no issues. Reached destination. Decided to leave truck wouldn't start. Turned over but wouldnot start. Hit the fuel tank and what do ya know it starts. Drove home no issue. Truck sat overnight went to go start this evening nothing. Fuel pump? Fuel filter? I havent hit the tank again yet. It's a 2003 h2 with just over 100k. Thanks in advance.

 

Sounds like fuel pump to me if you hit the tank and it started.

When you turn the key can you hear it prime?

 

I would test fuel pump preasure

 

Buy a quality pump like an AC Delco. The cheap pumps are junk.

 

I'm not sure but to replace the fuel pump you had to take down the fuel tank right

 

Yes the pump is in the tank.
