Fuel Pressure Check: Fuel-Injected
- Disconnect fuel pump connector. Crank engine for at least 5 seconds. If engine starts, let it run until it stops. Disconnect fuel hose at pressure regulator and install fuel pressure gauge using "T" fitting.
- Start engine and check fuel pressure at idle. See the REGULATED FUEL PRESSURE table. Ensure fuel pressure increases as engine RPM increases.
