What causes fuel pump to draw more current than intended?
There is also the possibility of a physical (mechanical) restriction in the fuel pump tubing, filter and/or pick up causing the motor to overload and draw more current than intended. That’s why you should measure the actual current draw of the pump in normal operation to rule that out.

What happens when a fuel pump goes bad?
The engine turns off if the combustion chamber’s fuel is inadequate or doesn’t have the proper pressure. The part that ensures none of this happens is the fuel pump, and it cannot work perfectly if the fuel pump relay develops any issues. A faulty fuel pump relay can also cause the engine not to start at all and be completely dead.
What are the symptoms of a bad fuel pump relay?
A bad fuel pump relay can cause many different symptoms. Here are the most common ones The fuel pump relay is an important component of the fuel system of your vehicle. The fuel pump relay gives the fuel pump power when it is time to build up fuel pressure in the rail.
