Hey can anybody help with this..

I just had a new LS B18b1 slipped back into my teg a few days ago... Bought from (Dekalb Auto Salvage)

I brought a couple parts that it needed from members of IA.com, but here's my issue.

1. The Dizzy i bought was faulty as hell, and i'm not sure how long it has left..
2. The My Cars been sitting in the garrage for almost A year with a full tank of gas in it.
3. While i'm driving on the E-Way, The car will just go dead as if my alternator gave out and i had no battery in it. (Alt was also bought from a Member of IA.com), i also put a new battery into her...
When i stop for a few minutes on the side of the road and check everything out. i get back in the car and start her up, she hesitates when she tries to start and if the starter was going bad, and / or if she has no fuel in the tank.
But once she starts she's good to go...

My boys at the shop are telling me it could be my Dizzy, Starter and/or Fuel Pump.

But whats crazy is it happens while it's raining more then it does when it's dry outside.
