      🙁 I have having a major issue and need help. I have a 2000 Saturn SL2. I had to replace the fuel pump. After replacing the fuel pump, the car will not start. Did a fuel pressure test and have 0 pressure. I have also installed a new fuel filter. Any suggestions would be wonderful

        Why did you replace the fuel pump? Was the issue properly diagnosed as the fuel pump the first time, or was it a no-touch diagnosis? Is ther power at the fuel pump, was everything installed properly and plugged in. Both outside and inside the tank. Has the battery died? Usually if the car was operating properly before a part was replaced and now doesn’t the “new” part or the installation is at fault.

          If you turn the key from off to on (without cranking) can you hear the pump run for a couple of seconds? If so, check that there isn’t a kink or blockage in the fuel lines.

          If it doesn’t run when you turn the key on, check that you are getting 12v and ground to the pump. You can use a test light or multimeter at the wire harness connection to the pump and watch while a helper turns the key on. You should see battery voltage for approx 2 secs. Then have helper crank the engine. You should again see battery voltage while cranking. If you cannot see voltage, then there is an electrical fault such as blown fuse, bad fuel pump relay, or damaged wiring.

          If you did see voltage, then the electrical connection on the pump itself could have an issue, or you could have gotten a bad pump. If you used an aftermarket pump that required splicing wires, recheck your work. While the pump is out for re-checking the connection, take the pump where you can apply 12v and ground directly to it to make sure the pump runs. I always power test the pump on the workbench before installing it into the tank because I have seen bad pumps come out of the box.

          Once you verify the fuses, relays, wiring, electrical connections, and that the pump works, reassemble everything and it should be all good.

            The fuel pump was weak. It was diagnosed as a weak pump. The car tries to crank just not getting the gas to the motor. The fuel pump was replaced yesterday. The battery is not dead and I can hear it engage when I turn the car from off to the run position.

              Next, now that power is confirmed (since you can hear the pump when you turn the key), test the flow from the pump. Locate the fuel filter. It is a metal cylinder with two hoses on one end and one hose on the other end under the car near the center. Disconnect the fuel line coming from the pump at the filter. Be careful of gas coming out of this line, it may have some pressure, and make sure there are no open flames or ignition sources nearby. Direct this disconnected fuel line into a clean container and turn the key on (you may need a helper for this). There should be fuel streaming from this line. If not, the pump is not delivering fuel even though it is running. There is a pipe inside the pump and sender assembly that if it is leaking, pressure will not build and the fuel will just recirculate inside the tank.

                Make sure you didn’t wire the pump backwards – it will run in reverse if wiring is reversed.
