Looking for a trustworthy mechanic to work on my 2001 Chevy Blazer. Possible fuel pump replacement but not 100% sure. It ran fine when parked, the next morning it was bogging out and loosing power, but after running for a bit, seemed fine. Parked it for another 2-3 hours, came out and it turns but won't roll over. Got it started and it stalled out after 50 ft. Now will not start without starter fluid to intake, but still stalls out. No gas at all in throttle. New fuel filter. Battery, alternator, and starter are all in good working condition. Please help me
