What can cause a fuel pump not to prime?
A leading cause of fuel pump failure is running the fuel tank low. Running such a vehicle out of fuel once can permanently damage the fuel pump. When the fuel level is low, the pump has to work much harder to produce the same pressure.
Can you prime a fuel injected engine?
Fuel-injected engines do not need priming. The injection system measures precisely how much fuel to spray into the cylinder during the intake stroke. … This means that if there’s not enough juice to both crank the starter (to turn the engine over) AND to fire the spark plugs, the spark plugs lose.
Do you need to prime a fuel pump to start?
The fuel pump has a check valve built into it that is supposed to keep pressure to the injection system when you shut down and vehicle sits. If the pressure drops then the pump has to prime the system to bring the pressure high enough to start and run the engine.
Should there be air in my fuel filter?
A fuel filter is going to have air in it unless you can bleed it. It starts out with air and then fills up. You can do a lot of parts changing or you can see if the problem is really what you think it is or something all together different.
What are the symptoms of having air in the fuel line?
What are the symptoms of having air in the fuel line? Air bubbles in a fuel line can lead to stalling, hiccuping or refusal to start. Keep your fuel lines free of air to help keep your car running smoothly.
Do you need to bleed fuel system?
Vehicles and tools powered by gas that have been stored for awhile must have their fuel lines bled so any air is removed before being used again. Fuel lines containing air can cause the engine to not run properly.
How do you prime fuel lines?

Why do I keep getting air in my fuel line?
Pinhole leaks in the low-pressure lines from the tank to the pump can cause this – the pump sucks in air through the hole instead of fuel from the tank. Check the condition of all the fuel lines, and the connections between rubber flexis and solid lines. Check any seals on the filter for the same reason.
How do I get air out of my fuel system?
To purge air from the low-pressure side of the fuel system, open fuel-line unions and bleed ports downstream of the pump, one at a time, beginning with those closest to the pump, and continue pumping until fuel, and not air, runs out.
