CORRECTIVE ACTION
Step 7.
Disconnect connector P17 from transfer pump and check for 16-24
Vdc between pins A and B.
If no voltage, go to Step 8.
If voltage present,
service and test transfer pump in
accordance with paragraph 4-37.
If transfer pump tests OK,
go to Step 9.
Step 8.
Disconnect battery cable plug connector from battery. Check
for continuity between TB3-19 and P17-A, and between TB3-1 and
P17-B.
If there is continuity, replace EECM (paragraph 4-64).
If no continuity, repair or replace wires as necessary.
Step 9.
Service primary fuel filter (paragraph 4-38a) and secondary
fuel filter (paragraph 4-40a).
Step 10. Disconnect connector P14 from high pressure fuel
pump.
Carefully connect voltmeter across connector pins P14-A and
P14-B.
Check for voltage that varies between 6 and 22 Vdc.
If voltage incorrect, go to Step 11.
If voltage correct,
replace high pressure fuel pump in
accordance with paragraph 4-41.
If problem continues, go
to Step 12.
Step 11. Disconnect P5 from EECM and check continuity between P5-L and
P14-A and between P5-M and P14-B.
Replace wires if damaged or no continuity.
If there is continuity, replace EECM (paragraph 4-64).
Step 12. Disconnect P12 from solenoid valve.
Attempt restart while
checking for 16-24 Vdc between pins P12-A and P12-B.
If no voltage, go to Step 13.
If voltage present, replace solenoid valve (paragraph 4-42).
