I dotice my fuelpump is at 60psi but going threw the gears it goes to 50psi. It never did that and in half a day my fuel pressure drops to 0psi and it use to stay at 45psi for weeks. Do I have a fuel pump problem.

13.0 is too lean. check fuel pump voltage, check fuel pump, check wiring.

Tell us more about your set-up. Fbody I would assume? Without knowing much it sounds like a pump, but could be a line leaking ever so slightly.

Devil is in the details.

Found out why my car ran ****. Found out you do not run race gas with cats. The cats were all melted and jammed in my y pipe. So I just want people to know that race gas is a NO NO.
