| Damn! Help Needed
I went to drive the 2000 G500 today, but it won't even turn over. Not even a click from the starter solenoid when I turn the key to try to start it.
All lights and indicators are working. My smart battery charger tested the battery, and says it is A-OK and fully charged. I drove it a couple of weeks ago with no problems
However, no power to the starter or its solenoid today.
Where to start to diagnose and fix this? This is the first time this has ever happened in 18 yrs of ownership.
TIA! |

Initial thoughts:
- Battery health. A true load test may be needed to rule it out or try a jump start instead.
- Fuses: Central locking, drive authorization, tow away sensor
- K40 relays: Engine Control and fuel pump fuses. If fuses okay, still could be on of those two relays themselves (not sure if the crank system needs a good signal from one or both of those relays.
- check for 12volts to the starter bendix with key turned.
- Have your tried your second key?
- What lights are you seeing under the mirror when you lock and unlock the truck?
- have you disconnected the battery negative waited a few, reconnect it and then try again.

Battery health is A-OK. My smart charger does a test with a load to see if it's OK before starting to charge or trickle charge.
Fuses for Anti-theft, Drive authorization, Central locking and Tow away sensor ar good.
Second key responds the same way - no power to the starter benix of motor.
Mirror lights are normal: flashing red when locking, flashing green when unlocking.
Will try disconnecting the battery negative. Have not done it yet.
Have not yet checked the K40 or its fuses.
When checking for 12 volts at the starter bendix, is this with the key in the "On" position or turned to the "Start" position? |

Check transmission shifter. Might need to cycle it a few times as it might think that it is not in park or neutral
Check brake light. This will confirm brake switch is functioning since the start system needs to see foot on the brake. |

All K40 fuses are good. although mine are all 15 amp. I also removed it from its case, and all solder joints are also good. |

Will check the brake light, but mine does not require having your foot on the brake to start. Will try it anyway. |

Have you exercised the shifter?
Mine doesn't require the brake either since I did the fix on the ignition switch. |

If you are still at no answer, I would try jumping starting it. |

Hi Dutch,
The Battery 12+ should be always at one of the Bendix poles, the Bendix gets actuated with the ignition lock/switch in the start position. The Bendix when actuated, moves the starter gear forward, and switches the 12+ Battery voltage to the starter motor.
The starter lock out switch, when defective , will block out the power going to the starter solenoid coil / Bendix

Along with what Karl said if you can get to the starter and tap it hard with a hammer or a long steel pole you might free it up. If the G has been sitting a long time this can happen. |

Still no success.
Disconnected that battery for about 5 minutes. Reconnected and still no power to the starter.
Exercised the shift lever a few times and put my foot on the brake. Tried again in both Park and Neutral on the shifter, and still no power to the starter.
If it was parked out6side in my woods, I would wonder if some critter might have chewed some wires. However, it's in a closed garage; so no probability of that.
I guess I need to crawl under the truck as see if there is power to the starter bendix. Also, will see if the STAR will tell me anything.
I really hate to have to flat bed this thing to a garage, but that looks like it's the next step. |

Thanks Karl. Where is that starter lockout switch located?
There is no sound coming from the bendix or the started when the key is turned to the start position. |

Thanks Mark. Will see if I can find the starter and tap on it.
If all else fails, do you know of any good indie shops. The one I used for years has retired and closed his shop.

I do not Know.
It might be in the shift console, my StarFinder only shows the 2002+ Models.
On the Bendix coil connection circuit #50 should have only 12+ power, when the ignition switch is turn to Start.
If you have 12+ volt there, but the starter is not turning - Bendix or starter motor defective. |

To get away from a flat bed towing,
make your self a remote starter switch, one wire to the #50 connection on the Bendix, and the other to the big pole with the battery cable on the Bendix as well. Use a nice momentary push button.
Oh yes, it helps to turn on the ignition...... |

Thanks Karl. Not sure I would know what is the #50 connection on the bendix.
I can't even get the bendix to make a click or any sound when I turn the ignition key to start. It's like it's totally dead down there, although everything else on the battery circuit is A-OK. |
