Hi, I could realy do with some help here please , I will try and keep this as short as possibile but I have a couple of problems I hope you may be able to help me with so here goes. I have recently bought a 04 plate sprinter recovery truck to help me in my buisness of vintage and clasic car restoration , but I am having some problems with air ingress into the system , here are the symptoms The engine will start and run at tick over for only a few seconds , then instantly stops , starts first turn of the key - 3 seconds then stops , turn the key and it starts for only a few seconds then stops , and on it goes . The clear pipe in the filter center is showing a hell of a lot of air in the fuel, so I decided to start at the tank and renew all the pipes from the tank to the filter and the return , in deisel quality rubber sheathed piping using proper pipe clamps .I also changed the filter ( genuine part ) and all the 0 rings on all the pipes I could get to . I also changed the low presure pipe from the filter center to the pump as it was showing singes of weepage. The T piece on the filter top was also changed, NO diference, still running for three seconds only . Now up untill recently the veichle was running just fine ,but there is a second item that has just appeard , - the edr red light is now on on the dash and somtimes it will run for 2 or 3 minites but as soon as you touch the throtle - it stops . Any advise would be most welcome, I live in a remote part of the Scotish Highlands and help is not readly available up here .( I serve my time on 1960s cars and trucks - common rail fule systems are a mystery to me . Thanks in advance - sorry it goes on a bit. Keith.
