Removal 1. Turn the ignition switch OFF and disconnect the battery negative (-) cable. 2. Lift the vehicle. 3. Remove the fuel pump control module mounting bolts (A).
Inspection 1. Measure the pressure of high pressure line by measuring voltage output between NO.1 and NO.2 terminals. 2. Inspect the voltage value whether it is sufficient to be regular value or not. Voltage = 0.00878835 * Pressure + 0.37081095 [PSIA] 3.
