Hey all, I have a Kia Sedona 2002 v6 that has been acting strange, and I have no been able to figure it out (however I think I am close.) It's a no spark no start. It gets gas, and compression is good. The ignition coils are 3 wire and all have 12v going to them, they have ground, and they have a signal (used a led as that is all i have). However, I noticed the wires to the coils are pretty bad, and when I measure the signal with led light; Coil 1 has a very faint pulse as it should be. Coil 2 and 3 the LED light flashes Bright on the signal pulse. Which I assume there crossed wires somewhere?

You're going to need to provide the year and engine for anyone to be able to help you efficiently.
Are these 3 or 2 wire coils?
Your description makes it sound like 3. How are you checking spark?
A 3 wire coil will make spark if it has power ground and control.

"Ground cannot be checked with a 10mm socket"
