  a knocking noise? im intreeged. Let me know if youve found it, my mates got exactly th same problem and even i cant figure it out. Im striiping his back down tomorrow at work and see if hes done everything  correctly.

i'll let you know i think the only thing it can be is it could be the codes been lost in the ecu as i disconnected it. But i just cant work it out it wont even idle it just splutters and knocks and thats about it do you know if the ecu losses the codes?

bluespurr - it's very bad etiquette jumping on the back of someone else post...mods/admins?

Wayne - sorry I can't help here as i'm not a V6 owner (yet...)

how many times have you tryed to start it again :question

[bluespurr]

quite a few but no luck, even tried bumping it

[slb]

are the fuel pipes on ok and the injecters conected up at the back :question

[Wayne]

is this an answer to my question... or somebody elses?

[TheBoy]

Wayne - have you got fuel at the fuel rail?

[Wayne]

Hi mate

fuel at fuel rail?  dont know what that means, you know what im like, lol

[Wayne]

i take it that the error code 31 is the crank sensor, and it needs replacing then chaps?

31 on a non running engine is non conclusive.

[Wayne]

what does that mean mate?
it could be ANYTHING?
so i could be sat with a car that wont ever start again?

how much will that cost to fix, or is that a "how long is a piece of string question"

It could well be the crank sensor, but we can't prove it.  But then it could also be a number of other things, including fuel pump/relay etc

Start from the top, Wayne - an engine needs 3 things to run - compression, fuel and a spark.

If the engine sounds fine turning over, then thats one ticked off.

Next question - do you have fuel at the fuel rail (slacken the unions off gently and it should come squirting out).
Third - spark.  Test the old fashioned way for now (old spark plug against something metallic and see if you have a spark.

From the last 2 tests, it at least gives a clue where to look..
