If the oil pressure sensor is defective and or fails to have oil pressure, it is a failsafe for engine protection. Try this: If the oil pressure gage or light show that oil pressure is present, but it will not crank, then open the fuel line at the throttle body a slight amount, ie. two flats then turn the key and starter just a wee tap or two and have some one watch the fitting for fuel pressure flow. If it leaks as it should, then you have your fuel pump working, however, if still no fuel then you must ck the inline filter under the frame. It could be completely clogged, there again, you could loosen the tank side of the filter and hit the key again and watch for leaks only if you don't get it at the throttle body. If you don't get any pressure leaks (you will get gravity leak on the tankside of the fuel filter) ie, squirting out, then you will likely have to replace the intank fuel pump. '
