Re: fuel pump timer?
The powertrain control the fuel pump relay. I am only familar with the late models, because it has been a long time since I had an early one (84). I looked at the 2000 MY service manual and found this information.
Anyway, when you turn the key on without cranking, the fuel pump relay energizes for about a second an a half. If you listen carefully, you will hear it shut off. You can repeat this just to make sure the pressure is up. Every time you turn the key on it will energize the fuel pump relay for 2-3 seconds.
The FSM spec says that fuel pressure should be achieved in 1-2 seconds. It is normal for pressure to be zero when sitting overnight.
Tip: I made it a habit to turn the key on and wait for fuel pressure before cranking. It will keep you from loading the battery too much when cranking excessively.
