FORD RANGER ENGINE PROBLEM

1994 Ford Ranger • 150 miles

3.0 engine, 4x4, automatic. New fuel pump and MAF. Starts, dies after couple seconds. Will only stay running if old MAF is plugged into connector, which takes any airflow reading out of circuit - hooked up to a dead device. No check engine light on when engine dies. Only time light is on is when making engine run by hooking up to old MAF. Have had problem in the past with ever being able to get a reading from OBD check light reader - engine light on and reader says nothing. Like it is not connecting to anything. Terrible gas mileage before it quit - about 14 MPG. Runs and drives if hooked up to old the old MAF and leaving old MAF laying under hood as I drive. Thanks for your help.

It should not run with old one not in the correct position.

There is change in air volume and it is not reading anything

a scan tool would be helpfull to see what the actual voltage is when running.

Mileage is due to this issue.

Check with a parts store for codes. They can blink them out and get back to us
