- Release fuel pressure. Install fuel pressure gauge. Turn ignition on and read fuel pressure. Compare fuel pressure reading on fuel pressure gauge with specifications in FUEL PRESSURE SPECIFICATIONS .
- If fuel pressure is not within specifications, check fuel pressure regulator. With engine running, connect hand vacuum pump and apply vacuum to regulator.
- Ensure fuel pressure changes as vacuum at regulator is increased and decreased. If no pressure change occurs, replace regulator and recheck system. For additional testing information, go to TEST HC in SELF-DIAGNOSTICS - EEC-V (GASOLINE) or SELF-DIAGNOSTICS - VILLAGER article.
