How can you tell if it is the fuel pump that is causing the car not to start?

Remove the gas cap and have someone turn the ignition on without starting the car. You should hear the pump run for a few seconds. If you do not, then check the fuse and fuel pump relay. If you do hear it run and it is very noisy it may be bad. If it sounds ok it can still be bad. The only way to know for sure is to run a fuel pressure test. Of course if you hear nothing and the fuse and relay are good then the pump is bad. Also make sure the fuel filter is not just clogged.

Simple, replace the fuel filter and if it still will not start more than likely the fuel pump is defective. But it can also be nothing more than a blown fuse or defective fuel pump relay. Check them both before moving to replacing the fuel pump.
