2001 Ford Ranger • 2.1L 4 cylinder 2WD Manual • 170,000 miles

My 2001 ranger cuts out when you accelerate. I can be in first and push down on gas and it will cut out. If I push on gas slow it wont cut out. It does it in all 5 gears. Ive changed the fuel filter and did a oil change. Ive used a fuel treatment also. I put new plugs and wires on it about a year ago. It starts OK and hasn't died on me yet. Any ideas on what to check next would be helpful. Thanks.

What you described sounds like a weak fuel pump. Have you checked fuel pump pressure?
