Re: Hard Start only when warm H2 2003
With engine off, key on and fuel pump commanded on pressure should be 55-62 psi. If you dont have a scan tool to command pump on you can jump fuel pump relay with jumper wire from pin 30 to 87 but dont leave it connected too long. Once max pressure is reached remove wire.
