Fuel Starvation

[amie.sprayberry]

I bought a 94 Ford Ranger that had been sitting for some time. I drove it over 25 miles home with no problem. I have been doing some work on it (non-mechanical) and took it for a ride and put $10 of gas in it. It ran fine, then all the sudden it acted like it was starving for gas and died, I got it restarted and got it home. I had probably driven a mile total.

Changed the inline fuel filter and it was horribly clogged. Replaced with a new filter and took it for a ride. It does the same thing. It will run for "x" amount of time/distance (anywhere between 5 blocks and 10) then it will starve for fuel. I can keep it from dying but it won't recover. As soon as I let it die or kill the engine, I can restart it and go for however long it pleases until it starves for fuel again and we start all over.

Any Ideas? Everyone I know is stumped. Checked EGR valve, MAFS, relay and even pulled the new fuel filter to see if it was clogged. I was not.

All I can think of is to drop the fuel tank and see if the sock is clogged on the fuel pump. Please help. I am running out of daylight and only have one day off.

Unplug the oxygen sensor and try again.

Thank you for responding. Where is the o2 sensor located and do unplug it and run without it and then plug it back in or just unplug and replug and start?

The oxygen sensor is in the exhaust. It infers if the charge was lean or rich by the amount of oxygen left over in the exhaust gas, and if the signal is bad it can end up pulling all the fuel.

Unplug it, secure the plugs away from the pipes, and then try driving it for a bit, see if it runs correctly.
