icebear Posted August 23, 2016 Share Posted August 23, 2016 My 300 tdi will not start anymore, think and hope its the lift pump, there is no resistance when pumping by hand, but when I crank the engine it comes fuel out of the bleed screw on the diesel filter top, am I right????

pete3000 Posted August 23, 2016 Share Posted August 23, 2016 if you have diesel out of the filter screw when cranking, your fuel filter and lift pump are probably ok and have a fuel supply. more likely next point of call is does the stop solenoid have +12v on it when cranking or at pos 2? you can unscrew part of it or replace it if you dont have fuel into the fuel injection pump, check the connection here and make sure the white wire and spade terminal are firmly connected.

icebear Posted August 23, 2016 Author Share Posted August 23, 2016 Thanks. Problem solved, tried to turn the alarm on and off, then it started! Quote Link to comment Share on other sites More sharing options...
ejparrott Posted August 23, 2016 Share Posted August 23, 2016 300 will run without the lift pump. I was going to say solenoid. It does have +12v while cranking, if it didn't it'd never start Quote Link to comment Share on other sites More sharing options...
Tal Posted August 23, 2016 Share Posted August 23, 2016 Thanks. Problem solved, tried to turn the alarm on and off, then it started! I have so been there Icebear, I turned on the imobiliser on my 200tdi without realising it, then tried for ages to get it to do anything at all. it was only when the alarm started going off and I had to undo the battery that I realied there might be a "something simple" causing the problem. turned out I had sqashed the imobiliser button in my pocket Quote Link to comment Share on other sites More sharing options...
