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.

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???
