*NO CRANK CONDITION (CONTINUED)
3.
EXCESSIVE RESISTANCE IN THE BATTERY CIRCUIT
Turn the ignition off.
Check the Battery Cables for excessive resistance using the service information procedure.
Did either Battery Cable have a voltage drop greater than 0.2 of a volt?
Yes
>> Repair the excessive resistance in the Battery circuit.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
No
>> Go To 4
4.
STARTER RELAY
Turn ignition off.
Remove the Starter Relay from IPM.
CAUTION: The Parking Brake must be on and the Transmission must be in park for a vehicle equipped with
an automatic transmission.
WARNING: When the engine is operating, do not stand in direct line with the fan. Do not put your hands
near the pulleys, belts, or fan. Do not wear loose clothing. Failure to follow these instructions can result in
personal injury or death.
Briefly connect a jumper wire between (A923) Fused B+ circuit and the (T750) Starter Relay Output circuit.
Did the Starter Motor crank the engine?
Yes
>> Go To 5
No
>> Go To 7
5.
(F924) FUSED IGNITION SWITCH OUTPUT CIRCUIT
Ignition on, engine not running.
Using a 12-volt test light, probe the (F924) Fused Ignition Switch Output circuit in the Starter Relay connector.
While observing 12-volt test light, hold ignition key in the start position.
Does the test light illuminate brightly?
Yes
>> Go To 6
No
>> Repair the excessive resistance in the (F924) Fused Ignition Switch Output circuit. Inspect related fuses
and repair as necessary.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
6.
(T752) STARTER RELAY CONTROL CIRCUIT OPEN
Turn the ignition off.
Remove the Starter Relay from the IPM.
Disconnect the C3 PCM harness connector.
Measure the resistance in the (T752) Starter Relay Control circuit from the Relay terminal to the appropriate termi-
nals of special tool #8815.
Is the resistance below 5.0 ohms?
Yes
>> Replace the Starter Motor Relay.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
No
>> Repair the open in the (T752) Starter Relay Control circuit.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

7.
(A923) FUSED B+ CIRCUIT OPEN
Turn the ignition off.
Using a 12-volt test light connected to ground, probe the (A923) Fused B+ circuit at the Starter Relay terminal.
Does the test light illuminate brightly?
Yes
>> Go To 8
No
>> Repair the excessive resistance in the (A923) Fused B+ circuit. Inspect related fuses and repair as nec-
essary.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
8.
(T750) STARTER RELAY OUTPUT CIRCUIT OPEN
Disconnect the Starter Relay Output connector from the Starter Solenoid.
Measure the resistance of the (T750) Starter Relay Output circuit between the Relay and the Solenoid harness
connector.
Is the resistance below 5.0 ohms?
Yes
>> Go To 9
No
>> Repair the open in the Starter Relay Output circuit.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
9.
STARTER
If there are no other possible causes remaining, review repair.
Repair
Replace the Starter.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

Diagnostic Test
1.
(A919) PCM FUSED B+ CIRCUIT
NOTE: The scan tool and cable must be operating properly for
the results of this test to be valid.
NOTE: Make sure the ignition switch was on while trying to com-
municate with the PCM.
Turn the ignition off.
Disconnect the C1 PCM harness connector.
CAUTION: Do not probe the PCM harness connectors. Probing
the PCM harness connectors will damage the PCM terminals
resulting in poor terminal to pin connection. Install Miller Special
Tool #8815 to perform diagnosis.
Using a 12-volt test light connected to ground probe the appropriate
terminal of special tool #8815.
Does the test light illuminate brightly?
Yes
>> Go To 2
No
>> Repair the open or short to ground in the (A919) Fused
B+ circuit. Inspect and replace fuses as necessary.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
