Expert: Ray Niemi Date: 7/9/2008 Subject: 94 850 won't start
Question My 1994 850 doesn't turn over -- when I turn the key I can hear it gasping. Electrics turn on and it has 6 gallons of fuel. The engine was replaced about 6 months ago and since then my check engine light has been coming on (the service center said it's for the mass air flow sensor). The air pump fuse was blown, so I replaced it, but nothing changed. The car started fine three days ago. Any ideas?
Answer Matt,
Well if the MAF is bad that will in some cases make the car not start. Do you have fuel pressure and how much? Is there spark? Read all the codes and make the needed repairs. The air pump not working should not have any effect on the starting...
