Table 3. “NO START”
(Solenoid does not pull in)
Step Condition/Action
1 Measure solenoid pull coil voltage (refer to Solenoid Voltage Check
section).
If voltage is in range, refer to Step 2.
If voltage is out-of-range, bench test the solenoid (refer to Solenoid
Bench Testing section).
2 Check linkage assembly for correct length and/or binding. Adjust linkage
if needed (refer to Solenoid Linkage Adjustment section).
If the linkage checks OK, bench test the solenoid (refer to Solenoid
Bench Testing section).
Table 4. “NO RUN”
(Solenoid pulls in but will not hold in)
Step Condition/Action
1 Measure the hold coil voltage (refer to Solenoid Voltage Check section).
If voltage is in range, refer to Step 2.
If voltage is out-of-range, bench test the solenoid (refer to Solenoid
Bench Testing section).
2 Check linkage assembly for correct length and/or binding. Adjust linkage
if needed (refer to Solenoid Linkage Adjustment section).
If the linkage checks OK, bench test the solenoid (refer to Solenoid
Bench Testing section).
Table 5. “NO SHUTDOWN”
(Solenoid pulls in but does not return to shutdown)
Step Condition/Action
1
Measure the hold coil voltage with the ignition switch in the OFF position.
If voltage is in range, refer to Step 2.
If voltage is out-of-range, test the solenoid (refer to Solenoid Bench
Testing section).
Check linkage assembly for correct length and/or binding. Adjust linkage
if needed (refer to Solenoid Linkage Adjustment section).
If the linkage checks OK, bench test the solenoid (refer to Solenoid
Bench Testing section).

NOTE: Be aware that there can be non-solenoid related causes for this
condition such as alternator circuit feeding back through the hold coil or
OEM wiring problem.
