2.0 tdi bkd engine cuts out in drive and just cranks afterwards

[Aidan Rowan]

Hello Guys, so my bkd engine just dies on me in the drive and just cranks afterwards, ive been dealing with this issue for long now. we have done the timing and replaced new cambelt, reconned the turbo, checked the injectors, in good condition, replaced the tandem pump, changed the fuel pump relay, changed the water temp housing. we have done absolutely everything to try and resolve the issue but no luck, diagnostics throws out no errors, tried resolving every mechanical issue that could also play a role still no luck, what could the issue be? we're out of options

When you turn ignition on you should here your fuel pump priming the system up i ask this question because theres 2 fuel pumps relays on this model that are inter connected at ecu pin nos a52 (switched earth) The most likely cause of your problem
