V12 won't turn over/crank
Hi,
Just went to start up my 92 5.3 V12 after 3 months in hibernation and it won't start.
Battery is good so it's not that. All electrics work normally.
No click from solenoid
If I have the headlights on and try to start they don't dim so no load going into the starter.
Car doesn't have an alarm or immobiliser as far as I know i.e I just have regular keys
I tried moving the gear selector from park to neutral but made no difference.
Any ideas?
Thanks
Rich

You could check starter function via that wire while you're there.

Well the relay is clicking so its somewhere between the relay and starter.
Next step is to get it jacked up and see whats happening down at the starter end.
I could hear the relay clicking but couldnt actually see it. Sounded like it was underneath the ABS unit? on the right hand side of the engine bay near the windscreen.

Perhaps easiest way is run an additional heavy gauge wire from earth bus bar at firewall to convenient point such as inlet manifold

Careful danger
The buzz bar at the firewall is LIVE not an earth. Do not do this or the car will burn up and the wiring fry!

WOW!!!! mistaking a Hot + for a _ can be a mess.
I did that. but, got away with merely cooking a pair of fusible links!!!
Soldered in a fresh pair and back where I was.
Case at hand. No start issue. I've one with my Jeep now!!!
May well be a parallel!!
I started with my VOM. 10+ across the posts. Good enough for a barely crank, but not enough to also fire.
Again probed cable + to cable _. Same value. Aha, that means the cable connectors are clean!!
Connected the smart charger. Very low charge measured. Charged slow for hours, Up to 90%. Not good enough, it will get more charge later this AM.
Your Case:
1. Battery charge status? Bare minimum, 12+!
2. Down and under with a jump from the firewall + post. Apply to solenoid small post. Clank and crank? Great, relay and/or wire issue!!
No crank? Apply to big starter lug. Starter spin? Quick as the under sized jump will get super hot, quick. Good, starter Ok, solenoid not.
Report back.

If it is the same as my 94, it is under the hood, on the right side, and the rear relay.
I said in my prior reply that if it cranks when the relay is jumper, the problem is before the relay. It could also be the relay. You could also try switching the horn relay (the one next to the starter relay) and see if that works.,

I realize this is an old thread, but I have the same car with the exact same issue. Can you tell me where is the starter relay located?
