Another place to look at is your injectors and connection tubes might have gotten loose.They are super critical on torque setting and sequence.Remember,on HCPR fuel system,you need to have at least 5000 psi to fire an injector.If you have a slight leak,the pressure won't get there.This is because the engine 150RPM crank-speed is not high enough to get the CP3 pump up to full head of steam.
