well the car will only run if i hold the key where the starter dis-engages...if my dad stabs the orange/lt blue wire and hits the ground button on his power probe the car will run on its own..

the stator sends a pip signal amplified through the tfi to pcm and once pip is seen ground to fuel pump is an output command from pcm
