When you shut the truck off for a leak test, turn the key back to ON right as the engine stops rotating and you won't lose Insite connection.

While you wait to source the blanking nuts, why don't you re torque all the high pressure connectors?

I turn key to off positio and as soon as engines stops I turn back to right, and it pretty much loses connection everytime. I'm not at home with torque wrench or I would try tightening all fittings. I am going to get cap nuts tomorrow. Maybe I can do video and give to Rawze, he could put audio to it.

Well after waiting for dealership to open this morning, they only had 1 cap nut not 5 like they told me on phone. Well I hope I don't have more than 1 injector leaking, I may be able to find it. But on the bright side, mil light has not came back on since I put relief valve on.

Maybe you got lucky. Order the other 5 caps so you have them for next time.
