Engine Performance problem
1995 Ford Ranger 4 cyl Two Wheel Drive Manual 200000 miles
My 1995 Ford Ranger will go but has no power.I dont have a fuel pressure guage but I have in mind that the fuel pump is not working properly. The truck will go but has no power, you can also hear a labor knock like the plugs are firing wrong (spark knock). Would the relay be a thing look at. If you feel that I am in the wrong direction please tell me. I have set my timing already. Please help.
As far as the fuel pump, it could be weak. Most parts stores will lend or rent you a gauge if you decide to check it. As far as the spark knock, I would start by checking the knock sensor. Also, make sure there are no vacuum leaks and the catylatic converter isn't plugged. Has the check engine light ever come on?
