Good Afternoon,

I have a cylinder 1 misfire. I have switched coil packs, cleaned injectors, switched injectors and injector clips. Still have the cylinder 1 misfire. I have narrowed it down to an electrical issue. All other cylinders are fine.

I wanted to know how to check the ignition coil harness clip for power, ground and signal. Electrical is not my forte!!! Any ideas on how to verify if that part of the harness is getting power!??

Thanks for any assistance anyone can lend!!

Might want to check intake manifold for leaks , tighten bolts down to spec. Those gaskets are ridiculously thin, i replaced mine with a thicker thermal gasket and no misfires since then

If like you said you have switched coil packs around thats probably not the problem , also try replacing spark plugs
