Diablosport Causing Engine to Defuel
#16
The CP-3 has 3 pistons to pressurize the rail and it runs at half the crank speed. When a cylinder is at TDC and firing the pump needs to be hitting TDC with one of the pistons or you get a rattle due to gear drive noise from the compression in both places causing the gears to kick.
To phase the pump break the lock nut on the pump loose and rotate the engine 20-30 degrees then tighten the bolt and check for noise. Repeat as neede duntil the noise changes or disappears.
It should take only to phasing attempts to make a difference. If it doesn't you may have another problem.

If it is phase and you get it out of phase, yes the noise will get worse, but, then you will know how to fix that.
