Chevrolet Repair: My 1985 Chevy Blazer 4x4 2.8L V6, throttle position sensor, fuel pressure regulator


Question
Why 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.

Answer
There 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.
