i just changed my fuel filter, smell completely like gas (ugh) but i was wondering how to get fuel into the fuel filter? and into the lines that were drained. Do i just tun on the ignition? Or just let the engine rotate for a bit withouth starting. Any help would be appreciated

Peace

The lines drain everytime you turn the car off. Just start the car!

Just turn the key to on and wait about 10 seconds for the system to pressurize. Then start it up.

Cheers!

the fuel pump won't be on when the key is in the on position... the fuel pump only operatres if the engine is being cranked... or the engine is running via the AFM signal to the ECU

to bypass this... there is a yellow 2 terminal conector near the passenger side shock tower near your stock air box. Place a peice of wire to connect the two terminals (short them) and put your key to the ON position... u will hear the fuel pump once this is done

Why? It won't start till theres fuel anyways. Just start the car like usual. It way take a few extra seconds to fill the filter.

Actually, since there is an FPR, the fuel pressure is maintained in the rails until after the car is turned off. If not, you have leaking injectors, removed your fuel pump o-ring, or a faulty FPR.

The pump does not run continuously in 'run' with the car off, or it shouldn't.




The correct answer is:
Jumper the yellow connector on the passenger side shock tower with a wire, then turn the car to 'run' for 10-15 seconds. Turn the car to off, remove the jumper, and start the car as normal.

There's the right way to do things, and the "it may not be right, but it works" method.

You obviously choose the latter.

Matlock

Show me where in the manual it says that. What harm is caused? I want proof! Untill otherwise, logically there is no need!

Matlock

When you fill up do you perform this procedure?

scathcart

No, your fuel lines do not drain when you fill up. You have a check valve in your fuel filter, and a fuel pressure regulator to maintian the rail pressure. Why would it go down?

scathcart

Unneeded cranking.
Unneeded wear on the starter, strain on the starter ground (I've seen it melt from excessive cranking sessions), strain on the battery...

It does say in the manual to prime your fuel system after discharging it.

Once again, there is the right way, and the "it works" way.

Matlock

That's not the question at hand! Why prime the system? Tell me Why? It will prime in seconds.

Matlock

We'll leave it at that.

scathcart

No, it won't.

Priming the system prevents excess cranking. The engine will start right away as opposed to 10-15 seconds.

Again, the "it works" method.

Priming takes 30 seconds anyway.
