How do you prime the fuel injectors on a 1996 ford Econoline E150 van?

To prime the fuel injectors on a 1996 Ford Econoline E150, first ensure the ignition is in the "off" position. Then, turn the ignition key to the "on" position (without starting the engine) for about 5 seconds to activate the fuel pump, allowing it to pressurize the fuel system. You may need to repeat this process a few times to ensure the fuel lines and injectors are fully primed. Finally, start the engine to check for proper operation.
