Fuel Pump Pressure Test
CAUTION:
Before disconnecting fuel line to connect pressure tester, fuel line pressure relief procedures must be completed.
- Place transmission in Park (Neutral for manual transmission) and apply parking brake. Loosen fuel filler cap to relieve tank pressure.
- On 2.5L Engine, disconnect 3 terminal electrical connector at fuel tank. Start engine and let run until engine dies from lack of fuel. Crank engine for 3 seconds to relieve residual pressure. Reconnect electrical connector. On all other engines, an internal constant bleed feature automatically relieves fuel system pressure when engine is off.
- Plug thermac vacuum port on TBI (if equipped). Disconnect flexible fuel hose and install pressure gauge. Start engine and observe fuel pressure. See FUEL PUMP PRESSURE SPECIFICATIONS . Relieve fuel pressure. Remove pressure gauge and reconnect fuel line using new "O" ring.
