From what I've read, injector failures are more common than coils. If you have an old spark plug, you can plug it in the end of the wire, then ground it (jumper wire wrapped around the threads and attached to good ground on engine), and start the truck to see if you have adequate spark, if so, the coil and wire are good on that cylinder.

i see, i guess i couldnt get away with an injector upgrade without a tune?
