Thanks - for the sake of a few quid I'll try this first, should be able to guess the state of the rubbish in the tank if I can get the old one apart.

Do I need to drop the tank to get to the in line filter? If so I might as well replace the pump and sender unit as I think this is on the way out, unless it's just a loose connection?

On the back of my recent experinces with the head and valves (poor fuel or additives = burnt out valves and seats), I'm sure now the fuel delivery system is on it's way out - seems to be surging when I'm into the red, goes away when I fill it up. Also the sender unit seems sluggish when I put fuel in - slow to register if I put in 10 to 20 litres. I know the obvious answer is to keep it full away from the rubbish likely to be in the bottom of the tank, but I don't want it to fail completley.
Can someone tell me if the filter is integral to the pump and if so, where I can get a pump from?

Thanks

Just given it a good valet - fallen back in love with it again.
Thanks all.

Car back and running ok. Problem sourced to low octane fuel, higher temps and valve deteriorating and making it's way up into head. Full rework, New seats, inlet valves relapping inlet and exhaust etc.
Never seen this before - expensive lesson learned.

Right, hope you're all sat down - problem is the inlet valves have corroded and started to withdraw into valve seats.
Full strip down of head, new valves, guides, springs,  re-machine valve seats, lap and put back together.

We think whoever had the car for the first 60k has been running on low octane (cheaper) fuel and long motorway journeys have damaged the valves so they don't seat properly, compounding the problem.

Sent a strong letter to Saab as the warranty only expired in November !!!

Get car back in a couple of weeks.

I notice the sweet smell when starting from cold, but thought it was unburnt fuel - similar to old petrol left in can?
Hope the verdict comes back soon from the garage - think we're at a point now where it´s got to be the head or valves not seating properly.

Second opinion from Saab specialist and he thinks it's valve timing too 
Question is wether can get by just realigning timing without new chains etc - car's only doen 80k?

Just booked it into indy SAAB specialist in Huddersfield - they're going to run through the ignition, maybe coil packs, but crucially, as you've been saying they can't see it being the timing. Being on a long run today and mechanically seems fine. Hope so as dealer just rang me to give an ' all in' price to do the chains - without any guarantees this will solve it, for about the same as a recon motor!!! Don't think so.
Thanks so far, hopefully the guy in Hudds will get to the bottom of it.

£24 from the dealer and yep, once I found it took 5 mins, top of block at pulley end under the plastic cover. Just remember to depressurise system and have the new one to hand!!
Dealer is getting back to me today with full breakdown of costs for checking chains and replacing any parts.

fitted sensor last night and took for a run whilst still warm. Misfire/flatspot still there under light load. Just started it this morning cold and same as it has been so not the sensor. I'll take it for a 200 mile round trip today to Leicester and back and see if the ecu can sort itself out - otherwise I'll book it in to the dealer to get the timing checked out

I will do - thanks.
Colder today and the problem seems worse, think we're on the right track - I'll fit this over the weekend and let you know.

Tell me about it! - 've also started to suspect my fuel filter may need looking at seeing another post - I'm always running down to the dregs. Could this be part of it?? Is it a seperate filter and easy to get at?

I'll get one on order today and fit before the weekend - with the smell I mentioned yesterday I'll get the oxygen sensor at the same time.
Thanks
