Ecm

[eupho]

I have finally managed to sort out the brakes on V6 2.8...replacement master cylinder saw to that. Feeling very pleased, I went to start it...no joy. It starts but dies immediately, blipping the throttle only saves it for a couple of seconds. I have done no other work on it and it has never failed to start. Clearly I did need to disconnect all the wiring on the intake side...I have checked that this is all reinstated.

 

My reaction now is that it must be in the control unit, is this a fair reaction....I read that if there is a problem in the ECM, it goes into what Haynes calls 'limp home mode'! Well I am home but can't limp anywhere! Help please. The following are some other things I have noted.

 

1) not being used to working on cars with high tech ECMs I may have perhaps not done things in the right order, in respect of disconnecting leads/battery etc.

 

2) the battery which was fine but was flat when I went to start it after reconnection. Does this indicate a short perhaps.

 

Is there anything I can do further to check/resolve the problem. As it stands not only would I be dependent on Ford dealer, but would also incurr the cost of them collecting it. This would be rather annoying having saved money doing the brakes in the first place.

 

IF the worst comes to the worst,how much will an ECM be?

 

Thanks for help, including those who advised on the brake problem, it was much appreciated.

I'd be very suprised if you've damaged the electronics, much more likely a missed pipe or electrical connection, triple check everything.

try disconecting the battery again, this may reset the brain.

Thanks for advice, will go and try again. I did pop into a VW garage and state symptoms, he suggested that it could be the immobiliser not reading the 'key'. Clearly I cannot do anything about this if this were the case. I did not get a red key with mine when purchased second hand. Do Ford have a 'master key' which could check the immobiliser theory...I understand that a new red key is expensive and certainly would not want to buy one if it did not solve the problem.

 

The Haynes does not cover the 2.8, is there a VW one to cover this engine as I understand it is basically their V6

 

Thanks for advice, any other welcome.

The best manual for the VR6 is the Peter Russek pocket manual, it covers the engine but mainly from the view of it being in a VW Golf, it's available online from http://www.vwbooks.co.uk/russek_manuals/

or off of ebay but it's cheaper from the shop direct :)
