I am in desperate need of help, we swapped out a 1996 Chevy 4x4 auto 4.3 to a 1997 5.7 auto out of a GMC Yukon got it all hooked up and wont start has fire coming out of the coil wire nothing down to the plugs been checking and changing sensors and still no fire to the plugs, I know someone else has ran into this and its hopefully a minor fix like connect a couple wires or a extra ground but it has me stumped, thanks.
