weird problem with coilpacks maybe?

[k2fender]

Okay, so I've been having a lot of trouble getting my s13 redtop to run right. Yesterday I was testing spark in the coilpacks. I put a screwdriver in the number one cylinder's coilpack, had someone try to turn the car over and I couldnt see any spark or anything. I tried it again while applying a little pressure to the coil inside the coilpack, and this time the car turned right over, but cut out right away. I put the coilpack back in and tried to turn the car over again. Nothing. I took it back out and put a little pressure on the coil again with the screwdriver and it turned right over, but cut out life before. I fixed the CAS timing, so that should fix the idle problem. I've checked grounds, checked wiring, and everything. I think it may be a short in the coilpack. Any ideas? Ive been having a lot of problems with the car randomly turning over. Sometimes I would crank it and nothing, other times it would turn right over. I need help asap. I'm ordering coilpacks tomorrow unless it sounds like im completely wrong.
