Quality fit and finish. If you have a 24 valve with a hard start condition, you can block off each injector one at a time to professionally find the bad injector that's causing low rail pressure. Our rail pressure was low at cranking (1000psi) after blocking #3 it went up to 7000psi and the truck fired right up.
