Long crank and no start

[Dawie #3]

Hi guys

I needs some advise with my e90 320i Auto

yesterday I felt my car loosing power on the highway, from 120km it dropped to 60km and later picked up speed (managed to get home), as from this morning the car is giving a long cranking noise and not starting

Any idea of what the issue might be

Thanks in advance
Dawie

Check you battery, fuel pump, crankshaft sensor, and fuse #70

Does the Rev counter move when you crank? If not, your ECU or crank sensor is poked. If it does move, then check for spark and fuel

There is spark, i got a diagnostics done which read as "Post catalyst fuel trim system to lean Bank 1" and "Post catalyst fuel trim system to lean Bank 2"

any idea what it could be

Hmmmm. It's basically telling you the fuel mix is wrong. Might be you don't have enough rail pressure feeding the injectors. Not a common fault though, but best to measure rail pressure and check against spec (which escapes me now).

You sure your VVT motor isn't messing around? No Valvetronic faults?
