1995 850 Starts, runs 1 sec, then dies

CTS functioning to spec?

Thanks beigg,
What is CTS? (Sorry, just new to a lot of this, and trying to save some cash on the repairs!)

CTS Coolant Temp Sensor.

MAF sensor would be a good item to swap, maybe with a salvage or known to work item.

Well, I unplugged the MAF and the car did the same thing..started then died about 10 -15 secs later. I opened the air box and sprayed some MAF sensor cleaner in to the pipe with the MAF sensor, and I used an electrical contact cleaner on the connector.
I started the car, and it started up, and continued running for about 30 -40 sec, getting very rough and rumbly, but it eventually cut out and died. It did run longer than usual (10 -20 sec.....but it did still die on me).

Then I pulled some codes from the A-2 OBD port...and got a ton of codes including "MAF Sensor signal" "Misfire on at least one cylinder" "Misfire on Cyl 1" "... Cyl 4" "...Cyl 5". I wasn't sure about these codes because I thought they are probably reading the fact that I disconnected the MAF to test it earlier in the day, so I cleared all the codes and started the car again, it died after about 10 sec's, and I immediately tested the A2 (Fuel System) codes and there are none!

Any other suggestions really appreciated!

Thanks,

Alan.

Swap MAF with known good.
Front O2 sensor after.

OK, ended up taking it in to a mechanic and he replaced MAF and everything seems to be good now (also replaced fuel filter but he didn't think it was causing the problem).
I was surprised because I thought the car should run / start with the MAF disconnected (which I tried)?
Anyway, seems to be good for now.
Thanks for all the help and suggestions.
