I have a 93 850 and was drving down the road and the engine shut off and still have power to everything. Will turn over but nothing happens. I have spark and fuel and wonder if anything else should check and threw a code for no rpm or cam sensor input and was wondering if was way to test the sensors instead of having to shell out the cash for new ones.

 

i'm gunna go with BOTH your sensors are dead, as it says "no input" meaning its not even giving anything out, just replace them and i'm almost certain it would start

funny story tho my 850 didnt start because of the camshaft sensor replaced it and she roared fro mthe dead...

 

thanks well the search begins for cheap sensors then and hope it does the job
