Hello guys, first I would like to say great site with lots of helpful info, sorry my first post is for tech info.

I have a 2006 f250 with a 6.0l

I have had issues with High circuit to injector #2 don't remember if it was 4 or 6 (sorry)

Here's what the shop has done, sent the FICM to get 58v upgrade and repair also replaced the bad injectors. This didnt fix the problem so I had to pick the truck up from the shop as i don't have the cash to keep throwing at it.

Today I pulled the injector harness off to test each pin. All pins tested good, but taking a good look over the harness I seen wire from the #2 injector that leads back to the body ground that's not connected to any thing. Any ideas on where to go from here?

 

I thought it was the ground but I can see the one I thought it was with the Ground Loop

Maybe there is 2 grounds

EDIT Looks like theres 6 grounds
