90 burban will not start, need some fast help

[84CUCV]

truck has a clean body. that why the guy bought it. hes going to be here in a few hours. i took off the radiator support. he wanted to save a few bucks so i kept it. i only have the one side in the fuse block in other side is gone. went with the radiator support.

do i need that in to start it. a guy at the dealer ship said it would start. so i took it off. its not tho.

any ideas? thanks

did you split the core support wiring from the engine wiring and plug the rest back in?

the plug should be able to be split in 3, the headlight stuff, the taillight stuff, and the engine stuff.

head light stuff is out. rest is back in.. crap starting to think something is wrong

Obviously something is amiss.
wire going back to the fuel pump?
Ignition wiring?
I've rewired these trucks so many times I can almost do it in my sleep. there really isn't a lot there.

Make sure you didn't accidentally hack something off.
I just threw away 3 different wiring harnesses, that probably had all that stuff still on them.

didnt see anything yet

Verify you have power back to the fuel pump first.

You would've lost your fuel pump wire when you remove the core support part of the harness. However, you have to have cut it to pull that part of the wiring off the truck.

I think fuel pump wire comes out with the tail lights, not the headlights.

 

[84CUCV]

would think the tail lights too. i didnt do any cutting

something as simpleas a missing ground? everything done properly with boxes grounded? Just a thought
