1993 Volvo 850 a lot of problems

favrice2000 · Post by **favrice2000** » 11 Nov 2009, 18:51

Ok my car won't start, it stalled out while driving and now it won't start at all. i replaced the started with a genuine Volvo starter that is perfect. still wont start though. it sounds like the starter is spinning but not engaging anything. i pulled the codes off of it and they are as follows
A2: 2-3-1, 2-1-2
A6: 3-1-4, 2-1-4
A7: 1-1-2
now does anyone have any idea how to get this thing back on the road? i don't want to get rid of the car and from what i've read people say these can last a long time if you care for them, i have 273,000 on mine. i need to get this thing going by monday to get to work and don't have a ton of money but really think it's worth what i can throw at it. thank you all very much, i've gotten a lot of good words said to me about this site and are very excited to see how you all can handle my problem.

212 front O2 sensor, 231 fuel trim secondary to O2

call fcp with your VIN number to get the right front sensor:

A6 314 bad camshaft position sensor this is what is your no start condition
214 rpm sensor may be secondary to 314

thank you very much, i'm going to go and pick up a used camshaft sensor from a low mileage 850 and try it mine. then from there work on the other three sensors there. thank you sooo much.

If you want save some money buying O2 sensors;
First, go to the site:
http://www.boschautoparts.com/VehiclePa ... inder.aspx
find the "OE Type - Exact Fit ", like for 93 850 its 13373, then you can buy from:
https://www.amazon.com/gp/redirect.html? ... ive=390957
or any other store.

UPDATE: replaced the starter and installed a new camshaft sensor, and still same problem. it sounds like the starter is spinning but not engaging anything. tested the solenoid and it was fine so not an ignition switch problem. any ideas? im convinced it's something easy and dumb that i'm just not noticing. could it have anything to do with the crank shaft sensor? or anything with the fuel pump of filter? any ideas people, i have tonight and sunday to get this thing running! i need help!

You might have major engine work.
Broken or belt valves if you timing belt broke while driving.

engine is fine, it was a coasting deal, the car stalled a lot since the cam sensor was faulty, and after it stalled i immediately stopped. worked out in my favor seeing as the engine is in great shape, no damage just the worry about doing the timing belt in it. some people say its hell others that it is super easy.

well I really hope that your engine is still ok. BUt it would be really odd if it was, these are interference engines and a single revolution of the crank can put the pistons into the valves with the timing belt broken.
I have never had this happen.
Out of curiosity, how long had it been since you replaced the timing belt? I believe it's recomended every 75miles or so.
Changing the belt isn't that bad if u have a bit of experience spinning wrenches, look in the repair database on this forum for some great instructions on timing belt replacement.

Good luck
