Hello friends
This is a Google translate
We have this car FORD S-MAX (WA6)1.8 TDCi 2007, QYWA engine, wine WF0SXXGBWS6R16191 in for repair at the workshop.
And must call for help, as we have no more good ideas
Well, we start it cold, it starts straight up and stop immediately, the signal for nozzles disappears on the scope,
I don't know if it's the engine ecu that cuts them off, after 5-6 start attempts it starts and runs great, doesn't set any error codes,
then it can continue to start, but if we leave it for two hours it starts all over again
We have measured everything I can think of. That has been changed, Cam sensor, crankshaft sensor, egr valve, pressure regulator in the pump, quantity regulator in the pump,
rail pressure sensor, used engine ecu, starter etc. All fuel is checked for air, have tried with the two pump hoses directly in a bucket of diesel
in the engine compartment.
If anyone has an idea, I will be happy
Please Richard
