I'm not quite sure of the name of the piece, but I believe it is the transistor pack. The thing that feeds into the coil pack. How do I go about testing it? I've been trying to diagnose and fix my stuttering problem for some time now, and I'm hoping my transistor pack is bad.
 
You can check resistance through it but only 1g coils should have transistor packs because of there high resistance coils. Do you have a 1g coil?
 
I just read your other thread and by the numbers you have your coil pack seems to be ok, I would try to find another, like test a friends or something but with those numbers it appears ok. And yes that was the right part to test. I also saw you had wires that were arcing. That will definalty cause a starting problem. Check the wires for opens too. If one has a tear or something, that will cause high resistance but it seems like you plug wires are causing your problem not the coil.
 
I have a different coil pack off a running car on there, and I have a brand new set of MSD plug wires. I have a new set of BPR7ES plugs and I believe all of my boost leaks are squared away. I've been figuring it's a boost leak, but I believe I have all of them taken care of. My power cuts out for a second after I'm at full boost for a second or so, then kicks back in.
