2004 1.9Tdi Auto Not Starting

[tahirti3]

my bad luck continues.timing belt snapped and after i continued to try starting the car, damaged the engine quite badly.was towed to garage and repairs carried out inc head,valves tappets etc etc.

battery was disconnected and now car wont start.it seems to fire for about a second and then dies.at first diagnostics would not connect but eventually said immoboliser ecu locked.

battery did die as well and then booster was used.

then stopped connecting to diagnostics again.swapping the instrument cluster for another one let the car connect to software again.

still showing ecu locked.

they have confirmed fuel is getting in and checked crankshaft position sensor but no joy.

getting desperate so any ideas guys.

many thanks

Engine starting for a few seconds then cutting out is usually the chip missing from the key, you haven't dropped the keys or opened the key fob as it can drop out easily.

Do you have a spare key you can try.

[seatkid]

Yes check the PATS chip (immobiliser) has not dropped out of the key.

thanks guys.the mechanic has the key so not sure if that is the problem.will take the spare to him now.could all this have happened due to car battery.if the key is the problem would it show as ecu locked?

he seems to know these cars pretty well but admits that this has really thrown him.

wouldnt be surprised if the mechanic threw your keys down and its come apart.but he wont admit to it.

If it starts with the spare, I suggest you get him to open the other key in front of you and check the PATS chip is there. If it isn't get him to get a working key sorted out (at his cost) for you as it is very expensive going through Ford.  There are other ways of doing it but it would be easier for you if he sorts it.

 I had a similar problem with my 2005 mk2 1.9 tdi Gal,,,it also used to cut off unexpectedly whilst driving on the odd occasion, in my case changing the Camshaft position sensor sorted the problem out....used a good quality BERU sensor from eurocpts , cheaper than original replacement  from fraud.....quick job by mechanic to change it...worth bearing in mind after checking the key PATS thingy!

Is this problem fixed? If so what was the cause?

[tahirti3]

thanks for the advice guys.got the car back a couple of days ago.he said he found a short in wiring behind the fusebox.

the car does have a new problem though.a very bad vibration at around 2500rpm.it is worse when under load but still there when revving in neutral.its like a teeth chattering vibration not like when a balancing or driveshaft issue.
