Hi
Can anyone help me with some engine bay pictures of a pre-face lift diesel engine bay/ engine. The car itself has now got
starting problems. It may either be lack of fuel or broken/split vacuum pipes. So hopefully pics may help.
thanks
-
Does the cold weather effect the starting ?
starts alright when hot
-
Well yes come to think about it.
Have fully charged battery overnight and this morning it tries , even shudders trying to start but alass lacks the final ooommmfff.
-
best thing to do is get a heavy duty battery,diesels use a lot of power in the winter months for starting,also check leak off pipes,common problem as this will cause air leaks.
-
If it is difficult to start when cold possible engine compressions
compressions need to be tight for a good cold start
possible heater plugs
-
How much Diesel is there in the tank?
-
I can send you pics of a 2.5 TD in a facelift, same layout. Have you replaced the Diesel Leak Off pipes?
-
Good Battery essential this weather, check GP voltage past the relay, measure each GP individually to ground (1 or 2 ohms each), crank off one of the injector pipes, is it spitting diesel?
Worst case get some Cold Start in to the Air Intake, will sound like a bag of spanners going around in a washing machine but should start.

Easy start could knacker the engine if used regular
-
guessing these dont help ;D

Used to happen mine a bit and what happened was the blank cap on the back injector was perished and letting out a mist(spray) of diesel. I couldnt actually see the diesel coming out with the covers on so I took the little cap off to check
-
thanks for all the replys.
will try out this afternoon.
hopefully.

at the front of the engine on the right hand side there is a silver cylinder with 2 pipe connections comming out. 1 seems to be fine, the other has nothing connected. any ideas as to why or is this a breather

Sounds like it's the EGR valve - some have a pipe attached, which is connected to the inlet manifold.
Whereabouts are you?

Thats ok.

neath.
if i was to bet the prob i would either say lack of fuel or air fault. could this be the fault?
-
classic lift pump problem by the sound of it, is it easier to start with a ful tank or at least over a quarter?
do a search on here lift pump blockage is well known! :y

Right, so you're not far away!
Before going any further, how much fuel is there in the tank?
-
between 1/4 and 1/2 of a tank
-
Just went outside in the pouring rain, turned the key and it jumped into life.
Could it be something to do with the frosty weather.
Any ideas?
-
I'm inclined to suggest changing the glow plugs. ;)
-
yes i think you could be right.
any idea of cost and which ones are best for the car.
-
I've fitted NGK's to the TDs that I maintain with no problems. Beru are also fine.
IIRC they were around 7 quid each.
Do you want me to get a price for them tomorrow?
Whatever you decide, do not fit the cheapo plugs that you find advertised on certain internet sites. >:(
-
if you could mate.
cheers

bloody car.
bought glow plugs. all set to replace.
had battery tested and looks like it could be that so took plugs back and got battery.
tried it and nothing. wont start.
took top plactic cover off and found a fuel line perrished so replaced and ............ still wont start
could it be anything else but glow plugs because it wont start at all now. >:(
-
As you've now got a brand-new battery, (so the engine's positively whizzing over), slacken one of the injector pipes at the injector end.
Get someone in the car, and try starting it, whilst you stand well back. You should see good squirts of fuel where you've slackened the injector pipe nut, as the engine's being cranked over.

Have you done a compression test ?
Could also be its mechanical fuel pump
-
Have you done a compression test ?
What for? - at this point (given the symptoms). :-\
-
Could also be its mechanical fuel pump
Which pump are you referring too?
-
The injector pump is what I am referring to
Its a mechanical pump but has bosch DDE digital diesel electronics management with fly by wire throttle
-
Loosened an injector pipe and did the test with someone in the car. fuel spurting quite happily.
?
?

Compression test needed to rule this out
diesel engines need a good compression to start in cold weather the warmer the weather the easier it is to start
hense the term compression ignition

Very true, but the BMW engine has a fairly good reputation as being bullet proof, and would have had to suffer some severe distress to lose compression. Is this a high mileage car? Has it been well maintained? Previous issues of this type reported on OOF have usually been the result of poor fuel supply, be it lift pump or injector pump. :y

Cleaned up some engine muck, opened fuel line and tested - ok
Connected up to my car by jump leads then tried to start it. eventually it started. ???
this car is doing my noodle in. if there was a major problem surely it wouldn't start whatever?
now waiting for the morning to test again.

Thanks for all your help in the past on this issue.
After taking the inlet off and all other parts i found various faults and glow plugs.
The car is now 100% and back where it should be - on the road.
Thanks again for all suggestions. :y :y :y :y :y :y :y :y :y :y :y :y :y :y :y :y
