Hello my name is ***** ***** thank you for your question.
Where is the fuse exactly located so I can pull up this circuit with this fuse.
Let me know..
Can you tell me what number fuse it is using this image I provided?
Hang on please.. reading....
ok, there is allot in that circuit.. Are you a shop? How good are you at electrical?
ok then. Please give me a few while I extract all the data from the service manual and share it with you so you can work on isolating this short. It will take me a while to do this so hang tight please..
As I was grabbing data for you, I just remembered something.. Have you checked your coils to see if any are blistered? or did you have to replace any coils cause they were blistered?
ok.. we may be on to something.. Were they blistered?
Why was it changed? What was wrong with it?
Ok.. Let me explain a old issue I recalled while looking up your info.
When these FX's were having coil problems, it was normally caused by the negative battery cable. To much resistance. So it would over heat the ground circuit and would damage coils. When this happens it would affect all the coils. So once this starts to happen, all the coils would need to be replaced with the battery negative cable or eventually it can burn out the Ecm. This sounds very similar to your issue.
Well, I am going to share the info with you. Here it is..
The second link is what I mean when I say a blistered coil. Did any of your coils look like this before replacing them?
If the coils were not blistered, then this may not be the issue. But I have provided you information which all has fuse 77 in the circuit so you can check and isolate the issue.
Do you have any more questions on this?
Well if the fuse blows as soon as you turn the key on, I would disable circuits to see if I can isolate the issue to a particular circuit. I gave you the Ecm power supply, Intake valve timing and Cam sensor circuit and coil circuit. so you can go through each circuit to isolate the issue.
If you have any more questions on this, please feel free to ask.

The body is more or less the frame. They have a subframe they use to hold the engine assembly. But the frame is built into the body
I thought there was another cable they recommended to replace which was from the body somewhere by cylinder 1 to the engine block also.
Do you have anymore questions on this?
