Inspection

1. Inspect fuel pump

1. 1
   Check the fuel pump resistance.
2. 2
   Measure the resistance between terminals 1 and 2.

Standard resistance: 0.2 To 3.0 Ù at 20°c (68°f)

If the result is not as specified, replace the fuel pump.

1. 1
   Check fuel pump operation.
2. 2
   Apply battery voltage to terminals 1 and 2.

Check that the pump operates. Notice:

• These tests must be completed within 10 seconds to prevent the coil from burning out.
• Keep the fuel pump as far away from the battery as possible.
• Always the voltage on and off on the battery side, not the fuel pump side.

If the pump does not operate, replace the fuel pump.
