BMW starting problem

Hi Pete
It's going to be a long shot over a forum but I'd go with fuelling issue going by what ya say
If the scan tool is not giving much info and no fault codes then it's something beyond what the scan tool can detect ,such as fuel pump issue or blockege common issue is the fuel filter.
Dont think that Bmw has fuel pressure sensor so ecu can't tell scan tool
If you disconnect fuel supply pipe to engine ,do you get fuel coming out with ignition on ?
When you switch on ignition can you hear fuel pump buzzing,located under drivers rear passenger seat ,if not check for power and ground to pump
I've had a few filters ( located under passenger floor) blocked .
Can you or have you checked fuel pressure/regulator
As always !
Have you got spark yes / no ? ( you have as it starts but cuts out) can you or have you checked crank senor signals?
Have you got constant supply of fuel ?

Hi

Thanks for all your ideas and suggestions,very much appreciated. I had already tried some of the checks mentioned and they were ok but there are others posted here i had not, so i will be checking them next and i will let you know my progress. Again thanks everyone for your help and taking the time to reply.

Timing chains jumped and its giving a misread signal on the sensor that's why it's showing up sensor fault on diagnostic check maybe?

try some easy start if it runs you have a fuel problem if not its an ignition or mechanical problem

Thanks for the replies.
