Fuel system priming

Warning: The pressure in the high-pressure fuel lines can be extremely high (as much as 23,200 psi), so use extreme caution when working near any part of the fuel injection sys­tem with the engine running.

1. The fuel system is primed by the transfer (lift) pump. When the key is turned to ON (without cranking over the engine), the pump runs for about two seconds, then it shuts off. It will also operate for as much as 25 seconds after the starter has been quickly engaged, then disengaged without allowing the engine to start.
Note: The pump shuts off immedi­ately if the key is turned to ON and the engine stops running.

2. Turn the ignition key to the CRANK position, then quickly release the key to the ON position before the engine starts. This step will energize the transfer pump for about 25 seconds.

3. If the engine doesn’t start, turn the key to OFF and repeat the previous step until the engine does start.

4. The fuel system is now primed.

5. Try to start the engine again. If it starts but runs erratically and noisily, that’s normal. It will clean out in a few minutes. If the engine won’t start, proceed to the next step.

6. Perform the previous fuel priming procedure steps. Make sure that there is fuel in the tank.

7. Crank the engine for 30 seconds at a time to allow the fuel system to prime.
Cau­tion: Operate the starter for no more than 30 seconds at a time. Let it cool for at least three minutes, then try to start it again.
