Little tests...

[94TeaL]

Well today i did a fuel pressure test on my car everything loooks good, but where should i be at when i turn th key then when i crank the car....
When i turn the key i get 40
When i crank the car, it sits at 37 or so psi...
When i rev it, pressure goes up...

also on scan tool my car has 25 spark advance at idle and 22-23 at rev...
Looked at other little things too my a/f seemed to get cured somehow...

WHen I turn the key to acc, the fuel press shoots to 54psi then settles at 42psi. After I start it, It stays at 42-43psi.

It is supposed to be at 38psi, but my fuel press reg is worn out from my nitrous kit.

When I am full throttle under a load, It will creep up to 46-47psi.

98+ cars have a highere fuel pressure then the pre-97 cars do. teal, you hsould see anywhere from 35-42 with the key on and the car not runnign. then it should drop a few psi when you start the car. dont go by cranking pressure cause it gets alot lower due too the car drawigng power for the starter.
