Checking Fuel Pressure
- With pressure relieved, remove air cleaner and gasket. Remove flexible steel fuel line between throttle body and fuel filter. When removing fuel line, always use 2 wrenches to prevent damage. Install fuel pressure gauge between throttle body and fuel filter.
- Start vehicle and observe fuel pressure reading. Fuel pressure should be 9-13 psi (.6-.9 kg/cm2 ). If fuel pressure is not within specification, refer to diagnostic flow charts A-5 and A-7 in this article. See charts A-5 and A-7 in this article.
- Relieve residual pressure as described in step 1). Remove fuel pressure gauge. Reinstall steel flex line between filter and throttle body. Start engine and check for leaks. Reinstall air cleaner and gasket.
