Picked up a very clean non-runner E46 318ci last night,
Engine Code N42B20A.
It starts after a while, But barely runs like it's just 1 cylinder... No power and won't rev.
No EML lights etc.. and it's showing no error codes when plugged in.
Any ideas?
Can you hear the fuel pump running
Could be a number of things very reliable engine [emoji3]
Didn't even think of that TBH!! :smiling:Quote:

Still no luck, No power coming to fuel pump in car..... :sad:
Also tried to start it with fuel pump wired to another battery and it still wouldn't start?
Have you had the car plugged in? I had one that slipped its chain no lights on dash and would not start.Quote:

I did manage to eventually get it started and move it, But it barely runs... Like it's just running on one cylinder.
Is there an easyish way to check the chain?
Iam not 100% clued in on n42 timing but this has worked for me in the past on other cars.
Get the bottom end to top dead centre. I.e take out plug in cylinder 1. Put dipstick/steel bar down into the hole it will rest on top of piston. turn engine over by hand until the dipstick is at its highest point. Wip the rocker off and i think there should be some markings on the ends of the cams closest to the fire wall. Also when the rocker covet is off check the chain to see if it's slack.
There is no marking as such if u do this look at rear of the cams they should have a round edge looking up and also should be 90 degrees to the cam box ..to lock flywheel its located under the starting motor.
