Minimum compression is 100 psi @ 200 rpm. The lowest cylinder reading should not be less than 80% of the highest reading. Perform the compression test with engine at normal operating temperature, spark plugs removed and throttle wide open. Normally I look for about 170 psi to 180 psi.

Fuel flow or fuel filter problems


The fuel filter should look like a short soup can on the inside of the driver's side frame rail between the fuel tank and the engine. If a new filter does not fix your problem, have the fuel pressure checked, your fuel pump may have lost pressure and need to be replaced (fuel injected models).
