Come on guys. I know there are some 6.0 wizards out there. Lets help him out. Bump for you man.

Thanks Eric!

Here's what happened. I swapped injectors. Ran great. Let run awhile decided to take it home on my way it fell on its face and started missing.... Then thru the code.... Now it has a constant miss in it.... It's only cylinder number one. Plugs all checked no issues wires traced no chaffing or bad wires..... So am I down to ficm?

I'd say if your ficm is showing 48.5 volts it's good..

Just from talking to Bryan tonight his FICM is showing 48.5 volts but he is on getting a little over 6 volts to the injector when it is plugged into the harness.

Could you of accidentally cracked the piece on the spool valve where the wires go into the injector? Its VERY easy to break it if you bump it when tightening the injector down. That would explain the symptoms, could of intermidantly made contact and then wiggled away and caused the dead miss.

bboteler · Feb 22, 2013

I'd say recheck all your connections, when you swapped the connections did the dead miss change cylinders? if so it's the harness...but an easier swap is a ficm if you have a spare just to take it outta the equation. If none of this works Im with STROKER and it's probably a wire issue and the injector isn't firing causing the dead miss.

It's not the injector it moves when you swap the harness around... I have checked all connections they seem to be fine. Couldn't find any bad spots I'm the loom either

doesnt moving the harness change the timing and cause a miss I think I would move the injector

smokedout250 · Feb 22, 2013

So I put the #3 harness on number 1 injector. Pull codes and it says that 3 has low voltage I think I may another bad injector....

I think you are headed in the right direction. I'm no expert but it sounds right.

smokedout250 · Feb 22, 2013

Looks like we have narrowed it down to the injector.... How do three injectors that aren't any good get shipped to a customer?.....
