car cranks but no start

What is your question?

car cranks but wont start. I have fuel pressure and spark. The car is an Oldsmobile 1994 88 Royale. when I checked voltage on the three wires to the cam sensor I got 11 volts on what I think is the power side but got 6.6 volts on what I thought was the the ground and nothing on the center signal wire when the ignition switch was on. Is there suppose to be voltages on both the outside legs of the camshaft pickup sensor connector? And if not where is it likely shorted? It was working good, and then some warning light would flash on and off while driving and when It was parked it would not start again. Also when the error lights were flashing on and off the speedometer would jump up 3 to 5 miles an hour more.

How long has your 1994 Oldsmobile 88 had this problem?

just happened
