A fuel pump sends gas from the tank and into the engine. Without this process, you have no combustion and no power. If your car doesn’t start with a new fuel pump, chances are the fuel pump is either not hooked up right or is broken.
Double check that the pump is correctly installed and all hose attachments are plugged in. Next, check for any blockages along the fuel line—this can also cause your car not to start.
If you’re stuck, don’t hesitate to head to a mechanic—while you’ll need to pay, a mechanic can help you resolve this issue.
