Help me follow this please
 

71 gmc 350, I hooked up the starter and can't get the motor to crank. If i jump the starter it will, but nothing from the dash. I replaced the ignition switch and lock. I have a 3 wire starter with the purple wire closest to the block and yellow capped off after it splits to the coil. I have no power to my coil. Any ideas?

Also if your looking under the hood, the farthest driver side connector on the firewall has a brown, brown and white, and I think blue or black wire. It is cut off. Is that for the emmissions and tranny that I shouldn't worry about?

I have the wiring diagram but still can't seem to figure this out. Thanks for the help.

if the truck is auto tranny check the neutral safety switck that is located on the steering column near the floor// thats where the purple wire is sopposed to be

The neutral safetly switch looks like was jumped with a wire between the 2 plugs. What do you think?

sounds liek a bad switch that someone jumped.

preplace the switch and clean the wiring and see what happens

would that affect me not getting power to cab in general? No lights or anything light up.

p.s. thanks for the replies by the way

i would just start pulling down bundles and checking for shorts dude..
sounds like a major issue, check where the wires are folded, and where they go close to high vibe/rub areas.

you gotta just start form the beginning and have a big pack of spices and heatshrink.

sorry to tell you man, gotta work from the beginning, hey here's an idea start at the fuze box and work your way out.

good luck

Well I did what you said...ended up being pretty easy. From the battery to the passenger fender, was missing a wire. Sorry for the elementry vocab, but good news, I found it. Thanks to whomever made the wiring diagram

"elementry vocab"? hell dude i cant even type worth a dang!

hahah well sometimes it really just needs love and checking everything, if you want to see some nightmares check the rest of the wiring threads here, and especially trailering wires... it gets bad dude..
have a good one
