You named it - Fuel pressure. Test that with KOEO and while running.

Internal leak of the intake manifold.
In case someone reads this. |

Internal leak? Care to elaborate? I thought the intake was still aluminum in 2002.

I have a '96 2.2 SFI, and it was still aluminum then. I wasn't sure when they switched.
