My 7 won't start. I went to take it out this weekend and it won't start. It tries to turn over but won't. For the last 2 months I've been occasionally having a stalling issue right after the car turns on when its cold, but it starts right back up. Never stalls when its warm.

Since it cranking, but not jumping over the hurdle I thought it might be a coil pack. I don't have the proper testing tools, so I pulled the plug and checked if I was getting a spark. The two trailers are strong, but the lead coil pack although sparking is providing a noticeably smaller spark.

Is this my problem?

 

I'd change my spark plugs, with your mods I'd go with 9s. If that doesn't help then take your coils to get tested.
