***warning, long, LONG, post!***
thanks for feedback! i hear what you're saying re fuse, i really do. however, i have cross referenced the handbook fuse table with my fusebox and found that everything that it says my particular model should have would fill every space in there (and i have a gap.) it appears that i should have 3 x 30A fuses in the box, at pos 5 (for electronic ignition and injection), pos 7 (selespeed gearbox), and pos 10 (oil pump supply, selespeed.)
could the explanation be that table lists two fuses for the sele gearbox (pos 7 = 30A, pos 8 = 20A), i had assumed that it has both, do you think it has the one 20A at pos 8, therefore the 30A at pos 7 is my oil pump one? if so, then why are two listed in the table, dammit?
....taking a breath.....and calm.
so good of you to offer to take a look, unfortunately i am in sunny scotland - helensburgh, nr glasgow (ish.)
thanks rarebear also. here comes my slamming the bonnet theory again.....
***please bear with me here, terry, i am groping towards a theory***
the pump is either coming on when the driver door is first opened, or not (for simplicity's sake, when engine is hours off.) i have been timing it, it 's consistently 12 seconds in this situation. if it comes on, car starts in 1 as normal and drives ok as long as sele light doesn't come on (diag confirms low oil pressure.) if not, i've no gears, don't even bother starting up in this situation anymore as last friday i had to call recovery because i had confirmed still no gears by opening door then starting the car up so many times in three hours that the old battery (the original, 4 years old) indicator had gone white (normally black despite my charger telling me it's full; did away with that issue by putting new battery in on wednesday
) i asked recovery guy to give the old battery a jolt anyway, opened the car door and the bloody pump activated, car drove home (a staggering one mile away; i had had to stop while whizzing home due to car at top of junction, grrrr.)
once a couple of hours after i was locked out i was sitting with driver door open, not for the first time that 'session', (no pump yet), popped bonnet and pump started (gears back and away.)
another time, same situation, but pump started when bonnet slammed.
(now when locked out i can not only be seen opening and closing door repeatedly, but opening and closing bonnet, also
my car is only 35K, nothing abnormal about gear changes to this point or when driving as long as no sele light comes on (which it is doing with increasing regularity. alfa hiding in garage behind our honda jazz
- from the symptoms, i have ruled out the accumulator, do you agree?
- due to low mileage, i was leaning toward sensor or connections anyway, before moving onto pump brushes (though husband is periodically stomping around and prone to muttering 'i think it's the pump, it's got to be the pump', etc.)
-in any case, what the hell gives with this physically jolting the engine thing? does it support loose connection theory?
when i went down to garage just now, pump came on after first door opening, not after subsequent ones (i'm aware it should be for short bursts up to, i think, 10 openings without ignition.)
strangely, directly after recovery callout battery jolt, after charging battery, and after new battery went in, pump was kicking in every time after repeated door opening (car cold on all three occasions.) could be a coincidence, but i have statistics education, tend to think analytically.
guys, i'm sorry sorry sorry for the length of this post, but i think it's all relevant. it's taken me 6 weeks to get this far doing 2.5 mile journeys into town (4 times daily as essential) so a lot of observation done - I'M reliable, if nothing else (sorry, that was an outburst.
thanks with a capital T for getting through this!
virtually everything i know has come from this forum. awesome.
