The output voltage of a properly operating camshaft position sensor or crankshaft position sensor switches from high (5.0 volts) to low (0.3 volts).

 

Do you think that a defective cam/crank shaft sensor could prevent the engine from running?? The wierdest part is the car worked oneday and then the next morning it was dead... It's been that way since it happened. Originally there wasn't any fuel pressure so I replaced the fuel pump, now I have pressure but it still won't run!!!

 

Yes! I'd start with the connections first. Make sure they are clean, free of debris and seated correctly. The crankshaft sensor is above the oil filter and the camshaft sensor is on the driver's side of the head.

 

The crank sensor is a PITA to get to. I remember having to change the sensor out because the 95 sensor wouldnt work with my 97 computer. The best thing to do would be to get those car ramps to get your car on. Drag it on with a truck or something. It makes life easy.

 

All right, thanks guys. I'm gonna test those sensors tonight, assuming I can get to them! They must cut fuel if the computer doesn't get a signal from them. I say that since I obviously have spark! I wonder if the computer cuts the injector signal or the fuel pump signal....



Now that I think about it, it must cut the fuel pump signal since the injectors are still firing...

 

Thats a good question. All I know is that when my crank sensor was unplugged I sure as hell wasent getting gas.
