I have and 1995 850 turbo. Yeasterday I started my

remove and clean throttle body clean or fit new spark plugs should be ok now if not get a diagnostic check done could be coolant temp sensor at fault

thats been happening to my car.
i also have an 95 850 turbo and we thought it was the battery but jumped it and it still wouldnt start.

so in the trunk under a mat, there was a metal thing that my dad said was a fuel pump, and he just banged on it a few times with the palm of his hand and it started working.

so i suggest trying that and if that helps at all, i would try to get it replaced asap (before winter) we check an auto parts store and it was $362 so it is costly.
