Title: New to Diesels Cold Start Problems
Post by: Yoke on January 24, 2007, 10:19:22 am: Hello all just wanted to pick some brains on a slight problem I have. 1984 Rabbit 1.6l great car runs like a top the only problem I have is getting it started. I DO HAVE A BENTLEY COMING just bought it off ebay and I have searched but have found nothing to help me out.

Injection pumps are new to me and I think that is where my problem is.

The car cranks over good speed, all my glow plugs work as does my cold start valve the problem is it won't start. But if I open the injectors and let fuel flow out and reseal the injectors it starts right up. No excessive smoke nothing just a smooth idle. My idea is there is to much pressure going to the injectors possibility?? Any help would be greatly appreciated.

Title: Fuel shut off valve
Post by: Yoke on January 31, 2007, 05:48:32 pm: Well after getting my bentley book and getting an hour to sit in front of Alldata it turns out my shut off valve was not opening on cranking?? So I could start it with the key in the run position with the remote starter switch but not from the ignition. The solution you ask........ I accidently left the key on when I was hooking up the valve shorted it against the pump and hey what do you know starts right up. :lol: Okay it was probably a bad connection of some sort but anyway it works thanks for all the help.

Stupid feature to prevent you from starting the car unless you're buckled in. If the wire to the seatbelt breaks, the car thinks you haven't buckled up even if you have.
