How long does fuel pressure hold?
Last night I was checking some things on the cars and left the fuel pressure gauge connected to the Corvette while I ran an errand in one of the other cars. When I came back about an hour later the pressure was around 10 pounds. I was just wondering if that's a normal bleed down rate. Just watching the gauge after shutting the car off, there is no noticeable pressure drop.
It should take up to 2 hours for the pressure to bleed down. If it goes down really fast, there is something wrong.
you have at least 1 bad injector
