My 2005 3.2 159 is playing up. Most of the time it starts fine but maybe once in every 10-15 attempts it turns over but does not fire. If the car's warm then it may fire but struggles to idle and quickly stalls. Reseting the ECU (disconnecting the battery for 45 mins) has fixed it every time so far.

The first time it happened the AA diagnosed a faulty low pressure fuel pump. I got this replaced at the local backstreet garage who reported a Low Fuel Pressure fault code was stored. Since then I've got a local Alfa specialist to take a look and they see the same code.

Their advice is to get the ECU checked before trying anything else. The problem is, I'm struggling to find anyone who can do it locally (Oxford). Most people say that they can't test the ECU from the 3.2. I've found someone in York who claims to be able to test it, but they need the whole car rather than just the ECU. I'm not familiar with the process but I'm surprised at that...

Can anyone point towards someone who can test my ECU?

3.2 ECU isnt directly listed on their site but it has to be worth a call... only thing is the 3day - week long turn around :(

Thanks richydraper for the info.

Unfortunately they haven't seen one of these ECUs before so can only take it apart and do a visual inspection.

I sort of guess that if they can't test it, no-one can. Looks like a new ECU for me, without knowing if I need one!

Before you go for the ECU have you double checked that the fuel tank, pump, filter and fuel balance pipe (in the tank) are all ok?

Check your fuel pump live feed. Run a temporary one from your boot lighter socket.

Did they fit a new pump or a s/h one?
Also, was it genuine OEM?

It's had a new fuel pump and the balancer pipe needed to be re-attached which made a difference to the fuel pressure at least temporarily

I would suggest you double check the tank and fitments all the way up to the high pressure pump in the engine bay before going to the ECU which may not be the problem.
