I was test driving a few Jeeps and noticed one at idle had 0(or slightly right above) fuel pressure. Is this normal? What does everyones Jeep have for fuel pressure at idle?

39-42psi depending on year IIRC.

Pretty sure spec is just above 15 psi at idle. The one you drove very well could have a bad sensor too.

You're confusing the oil pressure with fuel pressure.

^^ agreed. fuel pressure would need to be read with a gauge on the schrader on the fuel rail. fuel pressure on lates is 49 +/- 5psi. Oil pressure should be between 20 and 50 depending on rpm.
