94 X wont start...

ok...so i tore the dist box open and was testing the wires via a test buld (its all i ahve...and im going to describe this the best i possibly can... the wires im describing and the positioning is with the dist box in its normal position....there is a red wire on top (cab side) which also branches to the red wire on top of the fuel pump relay (labeled 30 on the relay) ignition on or off this shows a ground....there is a white with black strip wire on the passenger side ( relay number 86) and its live with ingition on and nothing with ignition off (neither power or ground)the black and white striped wire on the drivers side is a ground with ignition on and off (relay number 85) and a yellow wire on the bottom side (closest to grill) (relay number 87) which gets no signal with ignition on or off.... (possibly because it keeps blowing the eec fuse) the yellow wire i know runs from the eec fuse...which has power at the fuse (without fuse in). i noticed the fuse was blown so i swapped it out and then when i hooked power back up and turned the ignition on the fuel pump relay would click repeatedly really loudly... does this mean the red wire is grounding out and thats what is causing my problem? is this the power wire from the eec? does anyone know where this wire come from? if it is from the eec could this mean my eec is bad which is causing the "short out" or is it more possible to be a bad spot in the wire? any help and info is greatly appreciated

so i figured out its that red wire which is "shorting out" and causing my eec fuse to blow... but beings that the red wire, according to my chilton wiring diagram, branches to alot of things... (a/c, iac, maf, injectors, coil pack, and like 4 slots into the pcm/eec) how am i to go about this now... or does that just show signs of the eec/pcm being bad? also according to my diagram it leads back to the tc solonoid and the 3-4 shift solonoid on the trans... i didnt change these because i just dropped the used trans into this explorer... but could that be the reason its shorting out? maybe that is what caused the parts truck i bought (and got the trans out of) to have the same symptoms...will crank and crank but now start and no spark or fuel... just a thought...sorry for over posting i just wanna keep this updated to hopefully with the help from everyone else get this problem fixed!

now here again another thought...what components can cause this short out/ground out...the list of possibilities is (if my diagram is right) starting from the farthest from the dist box... iac, 3-4 shift solonoid, tcc solonoid, fuel injectors, evr solonoid, cps (camshaft position snesor), maf, eec/pcm, fuel pump relay, eec/pcm relay, icm,. which are the place to startby possibility of causing it and which cant cause this problem? and testing questions will come later

well i went ahead on my wild goose chase looking for this issue...thinking to check the last electrical plug i messed with before the issues...and sure enough it was it! the nuetral saftey switch wiring...i unplugged it and it solved the issue...and i plugged it back in and it was still fixed...so idk if it was crooked or something or if my switch is getting bad but i now have fuel and spark...now we'll see if she runs once i get a fuel pump in the truck =D thanks for all the help guys!
