The Injector line at the Firewall - You know, the one with the nail it.

Hi Everyone, Just want to first also throw my 2 cents in that this is the best Mercedes Site - period. All books and tools I have received - work, so please do shop here. Also, I have found things generally are easier to do than you expect.

220D Not Starting

I have a 220D that sat for several years, but previous owner said it ran last year after compression starting. I have no glow plug light before and after pencil type glow plug upgrade from mercedessource. Motor spins fast enough and acts like it wants to start. I can smell burnt fuel from the tailpipe, but it just won't catch. When the starter knob is pulled out to the glow position I do see the dash lights dim a little. I've found a couple of comments about W115 220d's not having a glow plug relay. What else can I check to verify function of the glow plugs?

Alternator Belt 'problem' ... 1984 300Turbodiesel...

Since I upgraded my glow plug relay to the type of relay that leaves the glow plugs on for a few minutes after start up, the alternator belts have been squeeling until the relay shuts off. I would like to put in a solonoid on the power supply to the relay with a momentary on button on the dash... But, in addition to that, I simply need to tighten the Alternator belts. It seems an easy thing to do on a car like this, which is so comfy to work on, but I can't seem to get the job done. It seems there should be a bolt, or a nut, to loosen behind somewhere, then turn the long, skinny hex shaped thing, and then tighten up the whatever. I can't find the bolt or nut, or whatever!

Small vacuum lines

I recently purchased a 79 300TD wagon. I have discovered many hidden problems with the car since I purchased the vehicle. The main one is the discovery of a 3" hole behind the battery and tray. It was hidden by a poor fiberglass patch job and the battery.This has been leaking into the car and sitting on the rear passenger floor boards. The floorboards are also rotting and hidden by rubber undercoat. Anyhow, when I bought the car I knew it needed a new heater servo and amplifier.
