Just got a 16v but having an engine problem, UPDATED

Incidently there are two small wire mesh gauzes in the WUR:



Remove the two banjo bolts that the fuel lines go to and you will see them underneath. In one WUR i found some brown stuff in them.

I had a very random problem where my car cut out over long journeys and i replaced things i didn't need to as no one on any forum could help. It could be the metering head itself, the flap could be stiff and not move as freely, the pumps, something electrical. My advice would be as Conker said, change the cheap parts such as the fuel filter which probably is due for changing but donor the rest.

Cheers Leon, I did notice that that particular unit is only held on with allen bolt which has a rounded head, the unit itself was actually moving when I was putting pressure on to release the banjo`s. When I get some time and more importantly some light I will take a look at all the suggestions here.

Thanks for the help guys, its much appreciated, Ill keep you up to date with what goes on

it does sound like it could be fuel starvation, I'd start by checking the lift pump.  As I said in my last post () unplug the main under car pump then turn the key 1 click, if you hear the in-tank pump prime then its working, if not then you need to replace it!

If that fails I'd take the inlet bolt out and check its not got the filter in it, then replace the under car filter.  Generally the injection filters don't go wrong unless some crud has got into the tank thought. And be prepared for a fight, the k-jet filters can be a b!tch to change!

there is certainly a whirr that lasts a couple of seconds coming from the tank when i turn the key to 1, is this what im listening for or is that the pump i need to disconnect?

[rubjonny]

both will prime at the same time, to check if the lift pump is working you gotta unplug the main pump so it doesnt drown out the sound of the lift pump

[Mk2George]

Gotcha, thanks very much

I'm doing the exact same thing. Think I'm going to get the garage to do the lift pump and filter though as I'm a bit worried about di#king around with the fuel tank. KABOOM!

My 16v has similar symptoms, especially at high speeds, so Im going to change the above and then possibly the injectors themselves. I might get the garage to give the fuel tank a flush as well.

Back again!

Ok Ive changed the fuel filter and tested the 2 pumps, both are working fine. I noticed the pump under the car is brand new so maybe the car has had similar problems in the past.  Tried cranking her again and no joy, just turns over. Oddly it seems more inclined to try and start with one of the injectors out? I took this out to see if there was fuel coming through and its spraying fine. 

I think i can now more or less rule out fuel starvation unless theres something else you guys can suggest I check?  Took out the plugs one by one and they had a very nice coating of petrol on them so cleaned them up and checked they were sparking which they are. Im putting the coating of petrol on them down to flooding the pistons with trying to start her so much this afternoon!

So once again im well and truly stuck, anything I should be moving on to check now? Maybe she will start once the petrol in the piston has evaporated by im not holding my breath!

And further advice is much appreciated, Cheers

ITS ALIVE! Spoke to a few chaps @work (I work in a BMW dealership) who have experience of Kjet injection systems and after disconnecting the 5th warm up injector she now runs, flooding the system apparently

So ill be back in about 2 days when somethnig else dont work lol

Happy New year
