So I just swapped out my 302 for a 351w efi and tonight I went to set the timing and following directions from other posts, I removed the spout and the truck died. I disconnected and reconnected the battery and checked all of the fuses but the whole truck isnt getting any electricity! I feel hopeless

 

That's why I discourage people who want to swap in efi in a older vehicle. It's a lot of wiring that can go wrong.

I don't know what year truck you are working on. I am assuming the 351w is a very late 80's early 90's model?

 

What spout?
