Fiat Ulysse ECU help - Please.

yes it might help

Hi Guys...


...UPDATE:

I have just had an Auto Elctrician out (On his way home)...

He plugged three (3) different machines in and NOT one could comunicate with the ECU.

The clicking in the 3 places (Relay next to the ECU, the R7 relay in the FuseBox and the Petrol pump) were still clicking all the time (a few clicks wer still active with the ignition off and keys removed).

Even though I charged the battery, it was flat -- and hearing the clicking intermittently after it was switched off with keys removed, I assume that this is what is draining the battery?

We have ruled out the Relay (next to the ECU) because I swapped it over for him - using the one from my Ulysse that we are currently using.

There is petrol getting pumped through as I can see it coming out of the top of the rubber pipe where it enters the copper? tubing to the engine.


Any ideas as to what this may be please?

He is talking about (If I want him to), coming out and spending the day on it, to "Pin" the ECU etc because he needs a good look at it manually as the ECU is not letting himput a machine on it. :_|

Your help is appreciated.

Sorry Mate, Only just got in and I didn't see your post, before posting mine, above.

Its this relay that powers up the ecu, if its repeatedly clicking then there probabl yis a fault in the wiring. Just dont want to see you buy a ecu & it still dont start...having the luxury of another car means you can spend more time & be 100% sure before spending £3-400 quid?

I have a pinout of this double relay somewhere...cant remember where though

Hi T14086,

Do you still think it is the relay? Or have I misread your post?

The Auto Electrician (AE) was talking about "Pinning" around to manually try to find the problem.

Aww Gawd..

I think what he is meaning to do is check supplies at ECU, however unless he has relevent wiring diagram this aint too easy as peugeot use those silly numbers (that wear off),impossible to read numbers on connectors and change wiring regulary...even the wiring at the double relay is sealed in

Have you got a wiring diagram of this that I could possibly have Please?

If you remember where it is, would you be kind enough to let me know so I can have a copy of it Please?
