I cannot answer your question because I don't know what it is.

some times the lifters get damaged or worn causing a leak down . do a compression test to check for a burnt valve. also check for broken valve springs.

by fine you mean 32 PSI, need to be 36 PSI for most of those horrible wheel sensors. The hud is probably shot and since Pontiac is gone, good luck getting parts.

You have 2 of them on the right side of engine 1-above the starter the other below the exhaust manifold.

Sometimes the simple answer is the best. The heads up display works off a mirror that reflects the image up to the windshield. The same way it works on fighter jets. (military) The factory spring is weak at best and in high heat or cold the spring breaks. Look down through the windshield in the upper corner of the HUD and if it's swinging there's your answer.

If I am not mistaken, it is under your car battery. Square box with a big wires connector plug with a 10 mm bolt in the middle or underneath your air cleaner. Good Luck.

those are typically pushed in there. There might be 1 bolt near the head that its holding it. Let me know if you find one. Weather has been bad here but I too have a 2004 Grand Prix and can check later

NO-bleeds it's self-sounds like you got ripped off on a new pump that was rebuilt. Take it back.

Any engine codes? Sounds like maybe a key code issue. Use or try your spare key
