If this car could talk I wish it would tell me what to do next :cry:

Right the issue is following the break down on the way back from the classic car show problem would appear to be the timing. I've checked the cat ie run it without the lambda censor problem continued no usable power.

He will rev up standing still but no heart under load. new plugs no change, new leads no change and spares coil pack no change :cry:

Fitted new timing belt from Fiat correct belt 125 teeth timed up with crank timing mark and upper cam shaft mark turned the engine over by hand two full turns marks on belt and engine and cam belt markers spot on.

The only thing the timing is still out using the strobe light on the marker in the bell housing it's retarded by 15 deg. :cry:

So what the hell am I missing :confused: :confused:
 
I doubt clutch is the problem as it does not time the engine. It is used to separate the engine from the gear box so you can change gears up or down or select reverse.
 
Thanks for your comment and your reasoning. A good indication of a failed or failing clutch engine would speed up but clutch would slip when under load.

The clutch is not slipping but your response would be correct if it was clutch failure.

What happens when the trekking is near or at normal running temperature at quarter pedal it has pull off and drive power up to about 10-15 mph on the flat and will not rev up any higher.

It does not kick or jump about, does not even cut out, starts up on the key no problem.
 
Things changed to date :-
4x New plugs
Full set of plug leads
New Fiat timing belt
Second hand twin coil pack :bang:

I now have a new pair of coils in stock but doubt they will sort the timing out?

Thirteen degrees out is a lot :cry:
 
Not particularly up on the injection kit but is it possible the ecu has massively retarded the ignition to compensate for the slipped belt previously. You may want to check around the injected crowd and see if there's an ecu reset procedure or if it's just a matter of unplugging the juice and leaving it.
 
Also is the timing definitely retarded, or advanced? just thinking about setting it up on the dizzy version you set it with vacuum disconnected to about 5 degrees btdc, but when the vacuum is reconnected that shoots it back round to about 15, so assuming the injection version has no vac advance to disconnect to check, 15 btdc sounds about right at idle. (thinking if it was that far retarded you wouldn't see it with the gun as the timing mark would disappear under the bell housing)
Maybe revisit the fuel supply side (as I think you are thinking now), start with fuel filter maybe as it's cheap, but more likely looking at fuel pump for such a sudden failure. Or, (and I refer the honourable gentleman back to my earlier comment) one of those newfangled sensor thingies but that's beyond my ken really. MAP sensor? must be something to read airflow into the throttle body....
 
i know with the cinqs old "6F" ECU that if you left it unplugged over night it would forget its map and learn a new one based on how you drove the car. this was good for (attempting) eco driving. as you could drive the thing with a light throttle and after so many hours of driving it would learn a lean burn ecu map.

maybe this will work for you?

I'm guessing with the age of this panda it's probs the same ECU

I agree with Andrew on this one, timing mark won't necessarily line up with a gun.
I too would look at fuel pump, blockage maybe.
 
It is all pointing now in the direction of the pump. I have had the offer of a of a working pump to try in my tank. I hope it proves the existing pump has collapsed insofar as it cannot maintain pressure and deliver petrol when requested.

It was also confirmed by several people that a ordinary timing light can not be used on systems run buy coil packs it will give a incorrect reading, it has to be digital lamp.

This is what led me up the path into thinking the belt had jumped three teeth :cry:

I hope to have it sorted out soon once I have collected the lent pump to use, thanks to a form members kind offer.
 
Back again with the final news on my problems with the Trekking being lethargic. It bloody sorted the submersible fuel pump was choked at a filter just below the pump impeller, it was like a very fine fibre board material.

How it got past the larger filter that fits to the base of the pump is beyond me :eek: But we fitted a new pump from Poland with a three guarantee and I'm a very happy bunny again :):):)

Thanks to all of you that have helped a old codger :worship: I learnt quiet a few mechanical tip from many people on this forum and off it.

The heart is back in PREDATOR :D
