My name is ***** ***** I will assist you.

What year is the 7500?

Does the cruise work with no issues? Do your brake lights work with no issues?

Are there any other issues going on with the engine?

Was there any work done like a possible valve job or any reason to be in the top of the engine?

When did it quit working?

Hi Jeremy, cruise working ok, lights good, no other issues with engine. Rebuilt engine not that long ago, brake worked ok, hi pressure pump left it hard starting, changed out. From then on brake went intermittent and then stopped working, tested rail with shop air and found o-ring leaking on #2 injector, replaced brake pistons with rail out. Changed out oil flow solenoid and the two sensors, checked the relieve valve, looks ok. Set brake back lash. No codes, switch works on and off. it's 06
Technician: Jeremy, Certified Truck/Bus Technician replied 2 years ago

Just to confirm that is stopped working after the repairs and the valve cover wasn't off at all since? I want to make sure nothing was uplugged or that the plug didn't work itself off by chance.
