| 300GD Not Starting
Hey guys, I've been a lurker for a while and I posted this topic over at ClubG.
I have a 1980 SWB 300GD with the factory non-turbo OM617. This is one of the earlier ones, the VIN ending in 005066.
The original owner did some stupid and cheap fixes to it over the first 20 years of it's life, and now I want to bring it back to glory. Only problem is... it's not starting. It turns over just fine; fuel squirts out of the injectors just fine; air is getting into the newly cleaned air box and intake manifold.
This was a sudden change; one day it was running fine, the next morning, it wouldn't start. I attribute the issue to my own stupidity -- the Glow Plug Relay had been replaced with a manual switch, and I left that switch on when driving for about an hour. The downside... that manual switch was added in addition to a shoddy aftermarket Glow Plug Relay. I think both are fried.
When the tools arrive, I'll be doing a Valve Adjustment and then a Compression Check. But as it was running fine, I'm assuming neither are an issue. I have a maze of cut wires under the hood, and am thinking about redoing all of the electronics.
One of the issues is that my battery (a new RedTop) has been drained over the course of a week as it sits. Something is drawing power out, and I highly doubt it's just that VDO clock in the dash.
Any ideas?

Its been ages since I looked at this. Shoddy wiring and an aftermarket glow relay were the culprits. All is back to stock now -- it starts up in 5 seconds. |

Remove the manual switch for glow plug and make proper connections to relay. Open the relay. At top end is a flat metal fuse between a screw on each side. They crack so fine you can't see it. Use 14G piece of house wire to jump the two screws. If it starts you need a new fuse or relay if fuse unavailable separate. |
