Starter Motor - Ground Circuit
A slow cranking condition can be caused by resistance in the ground or return portion of the cranking circuit. Check the voltage drop in the ground circuit as follows
Scheme 2
- Connect the 73111 Automotive Meter positive lead to the starter motor housing (the connection must be clean and free of rust or grease). Connect the negative lead to the negative (-) battery terminal.
- Engage the remote starter switch and crank the engine. Read and record the voltage reading. The reading should be 0.5 volt or less.
- If the voltage is more than 0.5 volt, clean the negative cable connections at the battery, the body ground connections and the starter ground connections. Retest.
- If the voltage is more than 0.5 volt, install a new cable. If the voltage reading is less than 0.5 volt and the engine still cranks slowly, install a new starter motor.

Scheme 4
- With the vehicle in NEUTRAL, position it on a hoist. See «LIFTING»(ref-348626-S31954056142009112700000)
- Disconnect the battery ground cable. See «BATTERY DISCONNECT»(ref-348661-S24834528062009112700000) .
- Remove the 5 bolts, the pin-type retainer (not shown in figure), and the RH splash shield. To install, tighten to 9 N.m {0.9 kg. m, 80 in. lb.}.
- Remove the starter solenoid wire nut. To install, tighten to 5 N.m {0.5 kg. m, 44 in. lb.}.
- Remove the starter solenoid battery cable nut and disconnect the starter motor solenoid terminal cover and cables. To install, tighten to 12 N.m {1.2 kg. m, 106 in. lb.}.
- Remove the ground wire nut and position aside the ground wire. To install, tighten to 25 N.m {2.5 kg. m, 18 ft. lb.}.
- Remove the 2 stud bolts and the starter motor. To install, tighten to 35 N.m {3.5 kg. m, 26 ft. lb.}.
- To install, reverse the removal procedure.
Scheme 5
- Disconnect the battery ground cable. See «BATTERY DISCONNECT»(ref-348661-S24834528062009112700000) .
- Remove the starter motor solenoid wire nut. To install, tighten to 5 N.m {0.5 kg. m, 44 in. lb.}.
- Remove the starter motor solenoid battery cable nut and position aside the cables. To install, tighten to 12 N.m {1.2 kg. m, 106 in. lb.}.
- Remove the ground wire nut and position aside the ground wire. To install, tighten to 18 N.m {1.8 kg. m, 159 in. lb.}.
- Remove the 2 stud bolts and the starter motor. To install, tighten to 27 N.m {2.7 kg. m, 20 ft. lb.}.
- To install, reverse the removal procedure.
