2003 blaster wont start anymore

sounds like the tors to me. it will start and idle fine all day but soon as you apply throtle it falls on its face, last time mine did that it was the parking brake sensor, it could also be the thotle sensor.

sounds like your engine is fine you just need to re run all your tors wires and check for bad/lose conections or just remove it all together and also make sure that little green wire comming of the cdi box is getting good ground.
