Thanks for the ideas, just under 1/2 tank, should not be a problem as the fuel pick up and pump is in a "tank", the white plastic ( now creamy coloured ) which holds a certain amount of fuel via the flap valve in the bottom of the "white tank", also the fuel return is flowing into this "tank", but maybe an indicator lamp fitted close to speedo area which lights when the pump is getting 12v, to rule that out next time it happens.
Earth strap checked and attended to last time this happened, extra earth from bat neg to ecm unit frame and extra earth to engine fitted last time. The round connectors to engine etc. where checked last time as well but will recheck those and its been raining since.
Will attend to tps earths to rule them out. Will also "clean" and lub inside tps. Will also wiggle test tps wires.
The maf sensor is very close to the battery casing but engine would "lean" the wrong way, but battery would lean the right way, so will check that also for movement against the tps.
The car did a faultless 700 mile round trip very recently to the south east with no trouble until about 40 miles from home, same fault, sudden loss of power which recovered, we got home all ok and flew up the big hill ( dinas mawddwy, the big hill ) no problems. Loss of power and pressing the throttle further makes no difference, then the power comes back. Also pressing the throttle right down does not seem to give power, the car seems to "hold back" suggesting fuel or breathing. Good economy and no smoke seen, no loss of coolant or oil.
Suspect a make and break contact somewhere but must research the hi pressure pump 3rd piston.
Advise on the 3rd piston please, operation theory etc would be very helpful.
The main loom bundle coming from the ecm may also move due to lh turn so will look at that also.
Will have some time and space this week for above once this bloody almera is dragged to the car park.
Englands glory is tempting but almera was all good until the engine died, fuel pump dtc so new pump.BUGGER BUGGER BUGGER !!!
What else is going to go wrong.
