Step
7
CHECK HARNESS BETWEEN ECM AND
FUEL PUMP RELAY CONNECTOR.
1) Disconnect the connector from ECM.
2) Measure the resistance of harness
between ECM and fuel pump relay connector.
Connector & terminal
(B135) No. 17 — (B362) No. 4:
8
CHECK POOR CONTACT.
Check poor contact in ECM connector.
Diagnostics for Engine Starting Failure
Is the resistance less than 1
&?
Is there poor contact in ECM
connector?
EN(H4SO 2.0)(diag)-63
Check
Yes
Go to step 8.
Repair the poor
contact in ECM
connector.
ENGINE (DIAGNOSTICS)
No
Repair the open
circuit in harness
between ECM and
fuel pump relay
connector.
Check the fuel
injector circuit.
