Engine Mechanical problem
1995 Pontiac Grand Am 6 cyl Front Wheel Drive Automatic

will not start. Have checked the fuel pump which has a psi of 46 at the fuel filter. The fuel filter has been changed. The car will turn over on starting fluid, and runs well, so I do not believe the problem to be the crank shaft senosor. I am wondering about fuses. What will keep the injectors from working. The enginine will not fire but has fuel in the rail and ignition. There is good pressure when valve stem is tripped on fule rale (schrader valve). The Chilton manual has been of little use to me.
