I have a 97 nissan pathfinder, 3.3 liter has 137,000 miles.. cranks but doesn't start, has new fuel filter, and i changed the timing belt and water pump at 107 000 miles, i can hear fuel pump hum with key on, I disconnected the line after the fuel pump and is shooting fuel with key on. I used my code scanner and it said camshaft sensor circuit P0340,EVAP SYSTEM P0440 I tested for battery voltage going to distributor connector, where the cam sensor is located when key on and and i get voltage, plus I checked the ground wire of that same connector with an ohms meter to ground and that's good. I'm suspecting either a camshaft sensor or PCM. problem. I'm getting spark to the spark plugs, it starts when I spray a little ether starting fluid in the intake, so i know it's a fuel problem. I've always worked on my own vehicles since working in the auto repair trade for 7 years, back in 1988-95 before switching to the equipment repair trade..
could i be missing something else to test.. before i gamble on buying a distributior, since the camshaft sensor isn't a seperate part and built into the distributor. what's your thoughts.
