Thank you again Ill go inspect all of these.

I went through the full checkout on the code. it appears it is being set when the power cycles on this circuit. one more bit of info is that when you hold this long enough for the engine to die the dash appears to lose power the lift pump stops running and the injector pump loses power. leave the key in the on position and I hear a relay click and power returns.

ok finally threw a 1689 code..

Yes,wait to start instantly most everytime and as you can see in video blinks on with every reset like full power loss.

Correct on all items I will confirm the ground wire in the morning.

First I will share I have a new lift pump and TPPS and crank sensor. this truck has the modifyed relay installed a few years ago. Today I had time so I put a test light to the Red and Green wire key on power source for the FP relay and also powers the VP 44 pump as far as I understand. When the engine is cycling off the power to the red/green wire goes away. there are no codes present at this time Adding short video. I'll add its a 1999 2500 with auto Thanks for any help.
