My 300d will not start

Ok guys, came in Friday night from work driving my daily driver, 300d shut her down as usual. Did not drive her over the weekend,Came out Monday morning the go the work, hit the switch spindling over real fast but will not fire off...never had this problem. checked the voltage to glow plugs seems good. so the question is when turning off the switch it shuts off the fuel at the injection pump so could what ever release this action caused it not to release the fuel shut off therefore not letting fuel get to the injector pump to fire off the engine????

Most likely to be a glow plug problem rather than fuel problem. Go to dieselgiant.com and follow his glowplug diagnostic sequence. You need to check the resistance of the individual plugs if you have pencil plugs. If you have loop plugs you can just look to see if the sqiggly wires are getting red hot. If they're not there's most likely a bad plug.

It would be helpful to know what Year of 300D you have. This would tell us what type of Glow Plug System you have.

To see if you are getting Fuel up to the Injectors you can loosen some of the Hard Line/Fuel Injection Line Nuts at the Injectors and have some one else try to start the car.

If you have a Glow Plug system that has the Glow Plug Relay on the Fender Well on the drivers side of the car (US models). Remove the Plastic Cover and take a look at the Strip Fuse. In the below pic of mine my Fuse cracked and my Glow Plugs did not work at all.

How does your glow plug indicator light behave?

IS this a 114, 123, 124 or 210 chasis?

Take your air cleaner off. Give the engine a shot of wd=40. Glow it and try to start. If starts and quits bad fuel or supply issue. If not glow issues or other. Divide and conquer is an old still valid concept.
