Otherwise you will be wasting $1,200+ on each injector you mis-diagnose or replace blindly, and may not even find the issue.

Just wanna verify I understood the quickserve procedure correctly. To test the high pressure relieve valve I would install the tester at the relief valve, idle truck and build 29kish psi using insite test. Once pressure reaches 29k it should leak more than 10 drops in 60 seconds. Correct? If did this right, looks like my relief valve is bad. Once it reaches 29k it’s still spraying out quite a bit.
