Question about 1988 Ford Ranger
There is a fuel pressure regulator on the fuel rail, and thats where the fuel return line hooks to. On that fuel pressure regulator is a vacuum line. Pull that vacuum line off the regulator and see if it is wet inside with gasoline. If it is not, and its dry, hook it back up. If it DOES have gas in the vacuum line, then there is a hole in the regulator diaphragm and the regulator needs replacing - simple task and $25-$100 depending on which one they used on your model truck. If this IS the issue - It is critical you replace the engine oil and filter , then again after 10 to 20 miles to get the gasoline our of the crankcase. Very important to engine life.
If not the above, then check to see if your oxygen sensor is functioning properly. They should be replaced every 60k miles.
