His theory (if I remember correctly) is the 610 ECU, being later than the GTA one, has some kind of cumulative fault counter and cuts the pump when it gets to that point. Turn off and on and you start the counter from zero
That came from me... I have the code, and had been playing around with these counters on a Fenix 3A ecu that has the same functionality.... found that back in 2012 /13 latest I think... the engine would randomly cut out at idle, restart on the ignition, and the engine would fire up fine...
Well this is a new one on me. I understand there being these counters for diagnostic purposes, that is one thing, but once it reaches a set level ..... it shuts the engine down by switching the fuel pump off ...... brilliant
Where is the logic in that ?
Clearly these faults that are being counted do not have any adverse affects on the running of the engine as if you force the pump to work with the earth strap, the Alp will run quite well year in year out.
If these faults are within the ECU then something is wrong with the ECU, on the other hand, if the faults are outside the ECU, what ever they are, they have no affect on the running of the Alp.
I find it very hard to believe that these ECU's were originally set up like this ...... well no ..... they can't be, as some 610's don't have the cut out problem.
If the faults were outside the ECU, ie:- faulty sensors, loom or TDC pulse generator etc, then the Engine would not be running reliably with the earth strap fitted.
I still think the only way forward is by changing over two ECU's as described before, so we can know if it is the ECU or the 610 causing this cutting out..
The very thought of this fault process putting members and their family's at risk is beyond thinking about.
Martin F ....... any thoughts on this ???
