I Really dont get this (help needed)

[gnrsoul]

just over a week ago i done the cambelt on my 318i m40 and since then i have had nothing but bother trying to get it to start???

at first was told maybe it could be down to the immobiliser but after checking things over it was down to a flat battery

ok
cambelt put on with locking tools
turned by hand more than needed to be on the safe side all good
put it all back together and no start

i was told to check spark, cps, coil and fuel

getting a spark
getting a good reading from cps
getting a good reading from coil
getting fuel

i really cant figer it out anyone shed some light on this im pulling my hair out

[Grrrmachine]

Without even putting the key in the ignition, connect a wire between battery + and coil + (the one fed by the green wire). Does the ICV start buzzing?

If it does, make sure the car is NOT in gear and that the handbrake is on. Now bridge pins 11 and 14 of the diagnostic plug; it should crank and fire.

To avoid the silly stuff, you have put in some fresh fuel, haven't you? And there are no massive air leaks anywhere?

[capri_rob]

Plug leads on the right way round ? I never manage to get this right first time when they have been off - if there is spark and fuel it should go

Connect up ignition wire 4 to connector 1, 1 on 4, 2 on 3 and 3 on 2, does it now start?

leads are right as in the numbers are on the side of the distributor cap ? firing in 1,3,4,2

i havent put any new fuel in as its only been off the road 2-3 months

and what will this do ?? Connect up ignition wire 4 to connector 1, 1 on 4, 2 on 3 and 3 on 2, does it now start?

i will try it

[Demlotcrew]

You might have the timing out by 180 degrees.

[gnrsoul]

if it does fire up the would i be right in saying there might be some damage??

[Demlotcrew]

If you used the timing tools then you might be ok! M40's are generally quite forgiving in this respect!

[gnrsoul]

i will go try the lead change and report back thanks

[gnrsoul]

nope switching the leads done nothing i would say worse ?

i have noticed if i just try turn it over it trys its hardest to start but if i open the throttle its like its not trying to start if that makes sense??

[Demlotcrew]

Oh so its trying to start? I thought it would not combust at all?

Hmmm, it still sounds like an ignition timing error. Sorry i cant help much more than that.

[Ant]

M40 can have issues pumping the hyd lifters back up if its sat for a while. Result is a non starter situation due to zero valve lift.

pull the plugs out and spin her over on the starter for approx 30 seconds, should make some decent oil pressure for the top end then, you can remove the fuel pump fuse/relay too if you wished at this stage, just don't forget to refit before moving on.

Refit the plugs and go for gold..........

[Demlotcrew]

Ant, i thought that the lifters only needed 'priming' when new or when they have been put on their side?

A good thought though!

[gnrsoul]

thanks i will give it a go
and cheers for all the help so far guy much appreciated

[Ant]

one from Experience Andrew, M43 is the worst for it

worth a mention, given the low ambients

[peterjcollins]

have you reinstalled the Crankshaft position sensor. It is held in position with an allan screw bottom righthand side of the engine.

Just a thought
Regards
Peter

[gnrsoul]

cps is ok i getting as spark and all reading are good im just about to go try what Ant has said.

WHAT THE F**K!!

car is running finaly but when i started to do the belt at the start of it all it looked like the belt was out a tooth so when i squared everything off with the tool would not start??

so i took the belt back off after trying lots of thing to get it started and it turned out to be the the cranck pully was in the wrong place witch looks to be a baw hair off, put it all back together turned it by hand more than needed to make sure and fired up first time ???

what i dont get is when useing the locking tool doing the belt it would not start but when i put it back to what it was like before i removed the belt it went first time but looks out by a baw hair???lol

[Demlotcrew]

Did you lock the flywheel and the cam?

[gnrsoul]

lock the flywheel and the cam and when i put the cam one on it was not square on the top of the head so squared it off and undone the cam pully bolt and fit the belt and then it would not start,
so after testing and playing aroud with it to find out what the problem was i had whet though everything and still nothing??

so i decided to lock the flywheel and put the cam back to the place it was before i fit the new belt (what looked to be a tooth out?) it went first time ?

[Demlotcrew]

Pass, not sure what could be going on there!

I can only assume that you had the dizzy rotor out by 180º and when you refitted it for the second time you put it on correctly, i doubt that having the cam out by such a small amount stopped the engine from starting.

Whats a baw hair? A Pube?

[gnrsoul]

i dont know why it was like that but it was not out 180 as i check and double check everything before doing anything

and yes to the baw hair lol

[Demlotcrew]

Thats a very small unit of measure, it would still have ran.

[gnrsoul]

CRAZY!! Huh, it runnig and i will take it out for a good run soon and see what it like?
im happy that its all running again as im moving house at the end of the month and its easyer driving it to my new house than any other options lol

just want to say a very BIG!!! THANK YOU. for all the help that you guy have givin' me and i hope i can return the favor sometime.

[Demlotcrew]

I think you managed it all on your own!
