No spark at the #1 spark plug. Relaced coil with new, replaced plug with new. Swapped #1 coil with #2, same problem. Swapped #1 plug with #2, same problem. Reading another post, Crank & cam sensor could be at fault, yet wouldn't it effect all plugs? Any help before I spend hundreds at my local mechanic would be greatly appreciated. Read somewhere it could be an injector? Thank you, Charles

Injector would not cause a no spark condition.

Check the wiring for the coil. If it is ok, I suspect either a flywheel for the crank sensor or a bad pcm

Thank you for your quick response. What voltage should be at the coil connector, 12v or 5? Multimeter work? Tried to read it before but I think I had the MM on wrong voltage, DC, yes? Thank you again, Charles

12 volts. At the coil. The other wires go back to the pacm and you need to ohm them out to be sure there is no break.

A scope would help from a scan tool to verify the flywheel signal I mentioned.
