Blurry I cannot make out the words 😭

two behind engine, one braided ground strap from engine to firewall, and g102 which is the coil pack ground wire and attaches to the front left of the engine by the battery - cable.

Would anyone mind telling me where Ground 1 is located. I've looked all over the end of the frame without removing the grill and bumper and can't seem to find it, but I'm having issues with my headlights lights and dash flickering. My gauge bounces and my monitor shows .3 volt range most of the time (13.6-13.9) but when the flicker occurs it drops to 13.0 or 12.9. I have replaced and relocated the PCM ground. I have done the big 3 with #2 ultra flex welding cable, as well as multiple new grounds with the #2. I can't seem to find this gremlin. It is progressively getting worse.

 

charm.li will have all of the ground locations for your truck.

 

Grounds being disconnected will not prevent "spark."
You have another problem.

 

I know it's been a while since this post but you are absolutely wrong. If the engine block grounds are not connected, namely the one ahead of the left engine mount close to where the negative battery cable attaches to the block, no spark will be the result! Seen many people forget to hook this back up and they will get a crank, no start due to no spark.
