Mazda 6 2011 diesel can't start

[rytismulti]

Hi, have Mazda 6 GH 2011 after crash, cranking but not start,
short history:customer buy it in auction says run and drive, after body repare starts and stop after few minits. in our workshop starts too 2 times for 10-15 seconds,
no troble codes stored, if disconecting fuel pressure regulator, MAF, rail pressure sensor all errors show in, if disconecting injectors errors not show, in live data fuel presure in crank 80000-42000 kPa, think so much.?
did see in some Mazda 3, in live data if cranking pressure 44000-38000 kPa and engine starts.
pressure regulator change, pressure sensor change, wiring check, supply voltage on ECU check.
No have solutions :(

Yes the rail pressure is more than enough to start the car. I remember I had problems after body repair and the problem was that the painters had screw the ground wire nuts on the paint leading no good contact with ground.
