STEP 7.
If fuel tank level is between 3/4 and FULL, measure continuity between J8-3 and
J8-2. If not open circuit, replace fuel level switch assembly (WP 0056).
STEP 8.
If fuel tank level is below 1/2, measure continuity between J8-1 and J8-2. If not
short circuit, replace fuel level switch assembly (WP 0056).
STEP 9.
If fuel tank level is below 1/2, measure continuity between J8-2 and J8-3. If not
short circuit, replace fuel level switch assembly (WP 0056).
STEP 10.
If fuel tank level is above 5/8 measure continuity between J8-3 and J8-2. If not
open circuit, replace fuel level switch assembly (WP 0056).
STEP 11.
Verify the problem has been resolved.
MALFUNCTION
Auxiliary Fuel Pump Relay.
CORRECTIVE ACTION
STEP 1.
On EMCP set ENGINE CONTROL switch to OFF/RESET. Set Battery
Disconnect Switch to OFF. Set DEAD CRANK SWITCH to OFF.
STEP 2.
Measure resistance between float level switch FL2B at J8-3 and TB5-21.
STEP 3.
If not between 600 and 800 ohms, repair or replace wire harness (WP 0088) or
replace AFPR (WP 0059).
STEP 4.
If between 600 and 800 ohms, check fuel level switch assembly (WP 0056).
STEP 5.
Verify the problem has been resolved.
MALFUNCTION
Auxiliary Fuel Pump Faulty.
CORRECTIVE ACTION
STEP 1.
On EMCP set ENGINE CONTROL switch to OFF/RESET. Set Battery
Disconnect Switch to OFF. Set DEAD CRANK SWITCH to OFF.
STEP 2.
Open control box (WP 0020).
STEP 3.
Measure resistance between relay AFPR-9 and TB3-10 (FO-4, sheet 2 and
sheet 4). If not between 40 and 80 ohms, repair or replace wire harness
STEP 4.
Verify wire from auxiliary fuel pump is connected securely to AFPV-1 (WP 0059).
If not secure, repair wiring (WP 0088) or replace auxiliary fuel pump (WP 0059).
STEP 5.
Verify the problem has been resolved.
