My 96 850 will not start, it will not turn over. My battery is good, did a tune up recently. So thinking it may be starter, fuel pump or fuel pump relay. How do I check?

 

Maybe cam sensor do you have spark,fuel and injection pulse?

 

I believe i hear the fuel pump working when i turn the ignition to II. but how do I check if I have spark. or fuel to the injectors. any advice

 

Since it does not crank over, try checking the wiring going to the starter. I don't know how hard it is to get to the wiring on the starter, but it should have power to the big terminal at all times. When you turn the ignition to start, it should have power to the smaller terminal. If both are correct, the starter is most likely at fault.

 

My car also failed to start and it turned out that it was PNP. https://volvoforums.com/forum/showth...t=29432&page=2

 

there is also a relay under the fuse box for starter. check that and also make sure that the alarm/antitheft is inactive. (no LED blinking on top of the dash). try hotwiring the big terminal on the starter to the small terminal wher the smaller wire clips to and see if it spins. That will atleast isolate the problem.

 

Figured it out. Actually my buddy who came over to help me found the problem. the fuse to the fuel pump was blown.
