Hi, Know this is old post but looking with help with something similar.
Looking for some advice/help in regards to a 2.0crdi Hyundai Tucson. The vehicle belongs to my brother and it has been off the road for the past six months after it cutting out on him on the motorway and having to be recovered. The vehicle was then in garage for three weeks after which time garage returned it to him saying they had no idea what is wrong with it.
Quick update on what has been done so far - all fuses and relays have been checked and tested, all sensors been tested, ECU been tested, fuel pump in tank been replaced all long with fuel filter.
Car cranks but refuses to start, but will run on easy start.
He told me a couple of months ago that he had checked the fuel pressure and all was well, however I am lead to believe that this is not the case and when he had the fuel rail pressure sensor off the other day he cranked it over and said there was no fuel coming out.
When he disconnects the line from the fuel tank pump and then turns ignition on it will pump fuel out for a few seconds then stops. I know that this happens if you do not start car as fuel pressure builds up at low pressure end and switches pump off but should it switch off if hose is disconnected and it is pumping into a container as it is building no pressure to switch itself off.
Slowly running out of things to check, all electrical systems seem to check out fine and I would say appear to be fine since it runs on easy start. I have yet to have my hands on it as I stay a couple of hours away and was trying not to get involved.
Could this be a problem with the fuel rail solenoid or could it be something more serious like high pressure fuel pump.
Any pointing in any direction gladly accepted as he is always on phone asking me to check things out for him.
