The easiest way without tracing each wire. Unplug the coil and injector on each cylinder one at a time until the fuse doesn't blow. The when you isolated the cylinder plug in the injector if the fuse holds then the coil is bad or the wiring is damaged. You will go through some fuses but you will know which cylinder is the problem and either fix it yourself or tell the mechanic to reduce labor cost tracking down the issue.

 

Does the fuse blow with just the key on. If it does you have an internal short in one of the injectors or the pink/ black tracer wire shorted to ground. The injector harness runs up along the side of the throttle body and is sometime the source of a short.

What's easiest way for me to trace it down if it's in the wiring

 

Thanks for the input on where to start. So, you think that a coil or an injector could be causing the the whole bank to short out? I assume that if the key blows the fuse, that would mean that it is a short in the wiring? If it blows the fuse when it is running it should be a coil or injector shorting out?

Again, thanks for the help and the wiring diagram. I will follow up when I find the problem.

Danog, where is the yellow/black tracer wire? is it in the main injector harness? I found a yellow/black wire in the diagram for the #6 injector in your post.


Thanks

My mistake it should be pink/ black is the power feed to that bank of injectors.

 

Thanks Danog
