Just what it says guys.. my '97 GT is having a missing problem so I tried checking the pump and I seem to be getting 30psi with the key on.

Is this normal or should it be around 40?

Would this indicate a failing pump?

Thanx guys,
Jason
 
30 is normal with key-on. You wouldn't have 40 unless it was severely hot outside and your ECM raised the fuel pressure to keep from boiling in the rails.
