Hello, My Omega B 2.5 td gave up the spirit a few days ago. I started it normally and drove about 800 meters…after that was over. It just went out and didn’t start again, starter and engine turn, but does not make any preparations to jump… before the sudden death of the engine no unusual noises or other characteristics were recognizable, just went out. I thought it would lie on the injection pump, the fuel switcher In the injection pump I tested (with auxiliary cable bestromt..der switcht) afterwards I screwed off the line at an injection nozzle and looked whether diesel arrives…kahm but nothing. The Esp has been leaking for a long time. The fuel filter is definitely not the cause…it is new. I got a new (used) pump at ebay, but this is still not working. Now my questions: Does the anti-theft or alarm lock work on d ie ESP? So a new ESP has to be learned or released first? Do I have to fill the new pump with diesel or forced filling (other fuel pump switch between) until it pulls diesel itself for the first time? I have been driving the car for 3000km on vegetable oil with two-tank system and therefore have no fuel pump in the secondary tank (diesel tank). However, the car also doesn’t start with vegetable oil from the normal tank with Krafstoffpumpe and there is nothing to do with the injection nozzles. Can it lie on the ESP control unit, is this possibly defective (does the esp actually have its own control unit?) I can’t imagine that both my old and the new ESP should be defective, can I test the ESP somehow differently than in the way I described it? Who can help me???? Thank you….
