1991 2.3 5spd. Fuel pressure is lost quickly when engine is just down. When key is turned on, the pump runs a long time before it stops. I have already changed the the fuel filter, fuel pressure regulator, and the fuel pump. NO large improvement was noticed. Interestingly enough, if you turn the key to the "ON" position and wait awhile until the fuel pump stops running, the pressure will stay up. I have left the key on for an hour and the pump did not come on. I assume that means the pressure integrity of the system is acceptable. I really don't know which way to go next, the truck has been a daily driver for 11 years and I want to fix it. I also have an 83 and an 86, one with a 2.0 carb. motor and one with a 302 V8.
