dead 320i help advice

[dazleeds]

ok just gonna start investigating why me grey 320 died

could a dodgy crank sensor cause the car to give a big black dirty puff of smoke then refuse to start again??

i have fuel up, it has full spark it should be firing but not a chance turns and turns but gets nowhere

someone suggested crank sensor but just wanted to double check get someoppinions

see what else i can check at same time

cheers

black smoke=well rich....is it flooded?is the obvious answer....
check plugs ,cap,arm

faulty crank sensor could cause i suppose -but check the easiest first as above.

Sounds possible mate, worth fitting a known good sensor from one of your other motors

if she has fuel and spark there is nothing wrong with the crank sensor so save yourself a job Daz

pull the ICV out of the intake manifold and crank her over a few times, she should run, if she catches whack the ICV back in and keep her running til shes up to temp

did ya try what ant said?

what was your spark like?
,allthough u may see a random spark -faulty crank sensor is not to be ruled out,but generally if it fails as it initiates the spark, often it results in a non starter.give it a look over m8 before u lash out.

didnt get much time yesterday
hoping i can have a good look later
but i really should be changing e rack on the 25 lol

last time i checked i had a very good spark on all leads
plenty petrol pumping
and the day before she conked she was running just right

[dazleeds]

ok spent a little time yesterday trying to start her again

spark strong fuels up and tried the icv off etc but still no joy
admit that she did seem to try just a little harder with icv disconnected but still no fire up

whats next??

have noticed a bit of whirring from the starter when you let the key go but its deff turning

I'm as stumped as everyone else
It may sound daft but if it backfired could it have jammed the throttle plate or damaged the AFM ?

bloody baffeling mate

didnt even backfire just seemed like it was down a cylinder very lumpy then puffed the smoke out and died on me
previously had run spot on was quick for a 320i too never had a single prob with her engine before this

[Martinaston]

I had the same thing a couple of months back just after i'd been using it for work, just went pop and wouldn't start for a couple of days and didn't have time to look at it, then when i went to have a look it just worked as normal I think it just wanted a day off.
You could try disconnecting the battery for a few hours to let the ECU power down

[dazleeds]

tried that had no batt on her for about 2 months now

bloody cars arrggghhhh

[Martinaston]

I'm still stumped i guess all you can do is go through it piece at a time and check everything over and i bet even when you get it going you won't be sure what the problem was
Best of luck

I'd look at trying another AFM - I've had similar 'backfire' symptoms to what you describe & whilst you still get wet plugs & a spark, the bugger won't start if the AFM's given up.
