compression test is easy you just take off take off the power wire to the coil so she cranks but wont fire then you take a compression guage and then screw it into the spark plug hole one at a time and turn her over. then u use a fuel pressure guage and screw it into the fitting in the fuel line and test it that way.

what should the pressure be?

what should the fuel pressure be? and the cylinder pressure should be? and how whould one go about adjusting the pressure if they arn't correct?

well- your stock FPR isnt adjustable and wont need to be messed with. but should be between 35-40 stock.
compression should be within 135-150 that is the reading of a healthy cylinder. all of your compression readings have to be within 10% of each other if there not you have bad rings or seals and the motor needs to be re-built.cool???
