Apologies for the blatant blag as I'm only an occasional visitor on here but as an ex-911 owner myself I thought it was worth a go [8|].
My day job is diagnostics on all kinds of cars but right now I'm a bit stuck on a 3.2 Carrera. It's a car the chap uses for about six months per year and this springtime he came to start it up and it wouldn't go. I got called to it a few weeks ago and found that it has no spark or pulse to the injectors but just occasionally it will start and then run fine; turn it off and try again and it refuses to go again.
When it is playing up I've got good power and earth feeds to the ecu and power to the coil and injectors etc, the engine speed and position sensors are perfect on a scope.
The obvious conclusion is an ecu fault so my customer found a place to fix it and they seemingly found and repaired a fault at the cost of £300 but it's still the same on the car! The unit has now been re-tested and passed a rig test.
Despite this, I'm pretty convinced that the ecu is at fault so here's where the blag comes in! Does anyone in the Stafford / Stoke area know of a spare ecu that could be borrowed to confirm this fault? If it does work I'nm sure the guy would be happy to pay a reasonable price for it.
Any other suggestions welcome also!
Thanks
