Iv a problem with my e90 2 litre diesel.
It started was drive home Monday night with no issue at all. Got in it Tuesday morning but simply would not start, spins over but will not fire at all.
Went to it the day after and it will now start briefly for literally a second then stops. Won't start again unless I ignition off then try again and will start but stop again.
Had a bmw diagnostic on it yesterday which there were no faults.
Only thing we could see was the fuel pressure would build to 400 bar on start up but soon as it fires drops to 30 bar. Does this every time now.
Iv had the pump out of the tank and cleaned ( wasn't bad really).
Can anyone please shed a little light on it please. Really struggling for ideas now.
Thanks in advance
