Test Description

The numbers below refer to the step numbers in the diagnostic procedure.

1. 3  - This step determines if the condition is located on the coil side or the switch side of the circuit.
2. 4  - This step verifies that the PCM is providing voltage to the fuel pump relay.
3. 5  - This step tests for an open in the ground circuit to the fuel pump relay.
4. 6  - This step determines if a voltage is constantly being applied to the fuel pump relay.
5. 13  - This step determines if the condition with the circuit is intermittent. If the fuse does not open, inspect the supply voltage circuit between the fuse and the fuel pump for an intermittent condition.
