Default Need help KOEO

Hi guys,

I'm currently having some fueling issue and saw alot of replies in threads that says to do the KOEO test ... anyone can tell how to do it exactly?

Are those instruction ok ?

Warm the car up.
Then shut the car off while monitoring HPFP pressure.
Turn the key to the on position(car is still off) since the AP doesn't get data when key is in ACC position.
If fuel pressure builds slowly rail/relief valve is good.
If all you see is ~60psi (in tank pump pressure) rail valve is bad.
You will not see 60 psi immediately -- the fuel pressure will not build up but instead it will fall steadily to ~60 psi

Thanks !

turn your key to the on position but dont start the car and watch your fuel pressure, on your AP. It should keep rising
