How do you find out if the car has problems with the fuel systems wiring when you installed a brand new fuel pump and the car still will not start for Pontiac lemans 1991?

You should be able to hear the pump run. If you can't hear it, check the fuse. Make sure you have power to it with the key on but it will only lite for so long if i remember right cause it is timed length of power sullied to until it starts.
