my volvo stalled while it was shifting it from 2nd to 3rd, and it didnt want to start afterwards. after bring toed back, i checked for fire, and there was no spark, after about an hour or two the car started again, but afterwards it stalled agan on idle. yet again it dosent have any spark, what could be the problem????could it be the ignition module???

 

Is Check Engine Light on?

For 1993, you can retrieve fault codes manually without any tool or equipment. That's what I would do first. I just replies to another post and attached code retrieval references. The post should be on the 1st page.

I can only assume your CPS (Cam Position Sensor) being faulty, which is somewhat a known issue on 850s. Other factors could cause no-fire symptom but if you have fuel pressure and no spark, the problem is probably within the ignition system. I would assume the module is ok.

Wait for other members replies as well.

thanks for the answear, after some reacearching, i would rather think it would be a sensor like you mentioned the cam position sensor, or it could also be a relay. its hard to find the problem now beceause it starts fine and everything and i dont want to go too far fearing it would stall again.


thanks again for the links,

Alex

 

My pleasure, let us know if the trouble develops again.

I've got a 93 and replaced my cam sensor about 2 months ago due to the same general problem... I've put a few thousand miles on it since with no problems
