Question about 1996 Chevrolet K1500
Not getting power to my fuel pump that I replaced and replace fuel relay to
Some fuel pumps come with a new harness and butt connectors to attach them. Peel back the loom close to the pump connection and check the connection if it has them. If it does have butt connectors remove them and solder the wires with heat shrink tubing. Keep in mind your close to the fuel tank.

Is the fuel pump really bad?
Our son's erstwhile Ford something had a shock sensitive switch that when tripped by a big pothole, shut the (electric) fuel pump off and had to be reset before it would function again.

I assume the fuel pump fuse is good?
The only time voltage will be sent to the fuel pump will be the first 2 to 3 seconds if the starter is not engaged. You will want to crank the engine over and check for voltage on the load side of the relay, circuit #30 at the relay.
Let me know after you check.

If you are sure the fuel pump relay is working, check continuity from the pump to the relay socket. These wires love to corrode. When you turn your ignition on, the fuel pump will only run for a couple seconds before it shuts off via the automatic shutdown relay. Make sure you are checking power within this window. The PCM (powertrain control module) is what completes the ground in order for the relay to send power to the pump. If the PCM does not recieve a signal from several sensors (mainly the Crank Sensor) it will not turn on the pump. You may want to check these sensors, is the check engine light on? You can scan it to see if any sensors have thrown a code. Be sure all applicable fuses are ok, the PCM may have its own fuse, check that even if the fuel pump fuse is ok. Your Truck may also have an inertia switch for the fuel pump which shuts it off during an accident. Check that as well.
