Somewhere around 40-50psi depending on whether or not your vacuum is high or low. High vacuum - lower by roughly 9psi. Low vacuum - switches to higher pressure by the same increment.

2002 Chevy tahoe won't start turns over but won't start


Most common problem is low or no fuel pressure. You will need to get a fuel pressure reading and post back.
If there is no or low fuel pressure then most likly the fuel pump is bad and needs to be replaced.

2002 Chevy Tahoe sputters and stalls out while driving.....


Fuel filter. Timing/timing chain. Idle air control valve. Idle sensor. Vacuum leak. Probably one of the above, but the filter is cheapest place to start. Change your air filter too, if you haven't for a while.

Is there a huel reset on 2001 chevy tahoe


Sorry there is no fuel pump reset on the Tahoe. If you have no fuel pressure, check the fuses and relay,and wire harness to the fuel pump from the inside frame rail on the drivers side. If you can hear the fuel pump working, check the fuel pressure at the shredder valve and there should be 60 to 66 PSI, if you don't you can try checking for 12 volt at the fuel pump wire harness at the frame rail. Good luck and keep me posted, be glad to help.
