It can either be the pump itself, wiring, fuel pump relay, on some fuel injection systems the injectors are also run on the same positive supply as the pump and therefor the same fuse so a problem with an injector or the wiring of the injectors in the engine compartment might be the problem.

What causes fuel pump fuses to keep blowing?
The fuel pump fuse may be damaged, a loose wire or bad wiring can cause the fuse to blow. If there is water in your gas tank, particles from the water will collect on components making them less effective. This includes parts of the electrical system such as sensors and resistors that are susceptible to corrosion.
Will a car start with a bad fuel pump relay?
#1 – You Can't Start Your Vehicle
This is by far the most likely symptom of a faulty fuel pump relay, but it's also one of the most overlooked. People automatically assume it's either a dead battery or bad starter, but if the combustion chamber doesn't have any fuel, you'll never get the engine started!
How can I get my car to start with a bad fuel pump?
Maintaining the Car Engine's Heat
So, one of the best tips to start a car with a bad fuel pump is to leave your car's engine cool. When your car cools off, it allows the fuel pump to reset without the need for pressure. Also, it would be best if you neither let your car engine get too cool or get very hot.
What fuse goes to the fuel pump?
Replacing Fuel Pump Fuse
Most fuel pumps will run a 15 (Blue) 20 (Yellow) or 25 (Clear) amp fuse. Using a fuse that's too small will cause the fuse to blow again. This is a normal condition as the fuse isn't rated for the higher amps of a fuel pump circuit.
Why is my truck turning over but not starting?
If the car cranks when you turn the key, but the engine won't start, it could be because fuel isn't getting to the engine. One potential reason for this could be dirty fuel injectors. Over time, the fuel injector nozzles can become clogged with rust, corrosion or debris.
Will a bad fuel pump throw a code?
Often you know you have bad pump because of difficult or complete failure to start. It will crank but not start. If it is running lean you can pop a code as noted above. That can be caused by a weak fuel pump, clogged filter, or a faulty o2 sensor or vacuum leak and other things.
What would cause a fuel pump not to get power?
If you there is no power to the fuel pump or the relay, then there may be a possible electrical issue with the vehicle. ... If there is an issue with the switch or the circuit, perhaps a wiring problem, then power to the fuel system may be cut off.
Where is fuel pump relay?
Most fuel-pump relay units are located under the dashboard near the steering column. In some cases, the unit is located in the area where the steering column is mounted or near the engine's firewall.
Does fuel pump need relay?
The fuel pump relay is activated long enough to supply the current required to turn on the fuel pump. ... At this point, the electricity for the fuel pump is supplied by the oil pressure sending unit. When you shut off the ignition, the fuel pump relay is engaged again, long enough to power down and shut off the fuel pump.
