RedLineMike Posted December 19, 2014 Share Posted December 19, 2014 Was there water in the fuel filter? I've seen a td5 that had suffered water in the fuel do the injectors which made it barely run & it sounded similar to your video Quote Link to comment Share on other sites More sharing options...
Henryk Posted December 19, 2014 Author Share Posted December 19, 2014 The fuel was black, but no water. Quote Link to comment Share on other sites More sharing options...
landy andy. Posted December 20, 2014 Share Posted December 20, 2014 Have you checked, changed injector wiring harness? Andy Quote Link to comment Share on other sites More sharing options...
Henryk Posted December 20, 2014 Author Share Posted December 20, 2014 I don't think that the wiring harness has problem. if i stop the car for 5 a 8 days some times when i take it run very well the first 2 minutes, but it starts failing again. at the beginning a have to start it more than 3 times because it works for couple minutes and stop again. I don't know but may be the fuel pump don't have enough pressure or the pressure regulator is bad or some injector is not reading. what do you think?

RedLineMike Posted December 20, 2014 Share Posted December 20, 2014 If the fuel was black, I'd be starting with changing the injector orings & copper washers, followed by pulling the fuel pump & making ssure it's clean Quote Link to comment Share on other sites More sharing options...

If you leave it long with the copper injector-seals blowing it can feed enough carbon back into the fueltank that it forms a gooey sludge which blocks the strainer on the end of the fuel pickup-pipe. The fuel-pump then kills itself trying to suck fuel through the blockage. Fuel-pumps are expensive; injector washer-kits cost pennies.

Henryk Posted December 20, 2014 Author Share Posted December 20, 2014 TODAY: Filter removed - Clean diesel pipe fuel return - empty before start (?). when engine started - clean diesel fuel tank - clean diesel Quote Link to comment Share on other sites More sharing options...
