Electrical problem
1991 Dodge Shadow 4 cyl Front Wheel Drive Automatic

i was replacing the fuel filter and the fuel line broke so I replaced it. Then I replaced the fuel pump and now I get no power to the pump or the fuse panel, I am stuck. What could it be? How do I fix it

At the fuel pump connector do you see a dark green and black wre?

12 volts comes from the Automatic Shutdown (ASD) relay. The relay turns on for two seconds when the ignition switch is first turned on, then it turns off. It is turned on again by the engine computer when the computer sees engine rotation, (cranking or running). Rotation is indicated by pulses from the pickup assembly in the distributor. The relay sends 12 volts to the ignition coil, alternator field, injector, and fuel pump or pump relay.

You should only have 12 volts to the fuel pump for the first two seconds after turning on the ignition switch, and when the engine is rotating.

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
