I have a non start issue with my 530d e61 where the car was running fine before I removed the injectors to do the rocker gasket and turbo while I was there but now after building it back up it refuses to start just turning over with the odd kick but not enough to start
It did have low fuel pressure but iv changed the hpfp and all the feed lines and return lines plus fuel rail from a known working car all pressures are now as they should be and its still the same just refuses to start considering swapping the injectors next as im at a loss with it
Iv done the very same job umpteen times on my car's and m8's car's with no problems
