General Fiat Ulysse ECU help - Please.

[T14086]

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:bang:

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

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

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

Fiat Ulysse 2.0 EL (1999) - I have the exact same fault as this member, and mine is STILL unresolved. (i.e. drove car out in the morning, stalled three times, after starting, until third instance, Warning light [looks like a K], which advised problem "Self Diagnosis, fault in the fuel-feed/ignition system". Also had that strange clicking sound.). First Auto electrician fitted a fuel pump relay, but still no spark or injection. Two weeks later gave up, transferred to a another Auto electrician, who "repaired track on board, as track was blown"?. He too has now given up, and said it's the ECU box. I'd be interested to know what the solution was to the other member, and what we could try further. I'm at wits end.

This issue sound quite similar to one im experiencing with my car. Any news on solutions? might give me a direction to go.

Hi, yes I did solve it. I had to purchase a brand new ECU. The biggest mistake I made was trying a second hand ECU, which initially worked (for about 5 starts), and then stopped working. We thought my car had blown it, and everyone was reluctant to put in a new one and blow that one too! Turns out, you can only use a NEW one, as the data on the old one had chassis/engine numbers etc, (cabin protection system), and it had conflicts with my details. Sort of using a new flash drive on a pc, you know you're not going to have any virus's or incompatibility. It is going like a boeing now, have not got rid of it. Other fault, I have a broken bolt on the throttle body, so tightened the cable ties holding it, and it's performing well. Some auto electricians can bypass some of the faulty dry joint points of the ECU, but in the end, I had done that, the car did drive for 18 months after that modification, but in the end, I had to buy the ECU. I spent R2700 on the by pass modification, and R6500 on the new ECU, so probably a better spend on buying the ECU at the outset. Love the car!

ok you lot i've got a similar but not identical problem!

ignition on and i get no engine management light on at all and car turns over but will not start!

I have a new ECU (supplied direct from Camco88 by the dealer i bought the car off) and yet when fitted it still does exactly the same? no management light all others on an wont start!

anyone any ideas?

and yes i have checked the dashboard bulb for the 'K' light!

Hi, it might be an silly suggestion, but as the ECU is specifically coded to your vehicle and can be done using a special "credit card" that came with your vehicle, or done manually with input by the dealer. It might be worth just checking if the manual system was used, and there is the element of human error.

thanks for that but this is a brand new ECU and it is set 'ready to go' it doesn't even need the immobiliser keypad to be fitted!

I think the main issue prior to it not starting was the fact that the 'K light' did not and will not come on regardless of how long you wait with the ignition on!

I am trying to find out what can cause this? - wiring fault possibly?
pump issues etc...

anyone else any ideas?

I fixed my issue with a new double relay. Car working a treat now. Although i dont have temperature display on the dash now - minor issue tbh.

Cost my £62 from fiat dealer for new relay.

Happy me
