Chevrolet Repair: My 1985 Chevy Blazer 4x4 2.8L V6, throttle position sensor, fuel pressure regulator
QuestionWhy won't my 1985 chevy blazer 4x4 2.8L V6 receive gas when I step on the gas pedal? The more I step on the gas pedal, it would want to shut off.
AnswerThere are NUMEROUS possibilities such as a loss of fuel pressure or a loss of ignition. Without performing some extensive fuel pressure testing and ignition testing an accurate diagnosis is most impossible.
The most common faults are:
1. Weak Fuel pump.
2. weak fuel pressure regulator.
3. faulty TPS (Throttle Position sensor.
4. restricted exhaust such as a partially plugged catalytic converter.
