Coil packs

[Bluecifer361]

Well it looks like I’m getting no spark to a spark plug I have replaced the wires next is the coil packs the oem ones seem expensive so before I buy one is their a aftermarket one anyone suggest

I would go with a good used OEM coil pack rather than a new cheap chinese coil pack. But are you sure that the issue is the coil pack? Not the PTU or ECU?

I’m sure what the ptu is but I took each spark plug out and plugged them into the wires laid them out on a towel and had my wife crank the engine only one had no spark

Did you ground the spark plug cases when testing?
Note that with a waste spark system both spark plugs connected to each coil fire together.
Try swapping the spark plug that doesn't fire to the other coil to see result.
Is this a 4G63T or 420A?

4g63t

no I didn’t ground anything I just laid them on a towel do I need to ground them if so how would I go about that?

Yes you MUST ground the spark plug casings. Clamp them against some engine metal that's unpainted. Or use battery jumper cables on each to ground. Note that both spark plugs on a coil are actually part of the same electrical circuit (one on each end of the secondary coil's winding) to ground.

You need a spark tester. If it was a coil it would be 2 cylinders. The control module could cause that.
