96 Yukon Will not stay on.

[Jbaez2011]

Hello to all I am Will and I am new to the forum. I am having problems with my 96 Yukon 5.7 Vortec, It will not start unless fuel is added to throttle body however ofcourse after seconds it will shut off. I checked fuel pressure and it is good but spark plugs are new and my buddy told me he put the spider in before I bought it from him. Please anybody suggestions? I am not a Mechanic nor am I even close to that I am just a guy who wants to get his truck started. LOL Oh and with limited funds.

RE

I went and got new cap/rotor spark plugs and wires. I put gas in throttle body start it and it runs for however long youd like. When you put it in gear or give it alot of gas it bogs down and shuts off PLEASE HELP

I would say your spider install got dueced. Probably put the injectors in the wrong holes.

okay so update I got the truck running the spider pins inside the male piece one of the pins were bent. Replaced it with new one and replaced fuel pump as pressure was 45 psi. New problem the truck bucks with brake on when u put in drive or reverse. Ideas?

is it possible you have a vacuum leak somewhere? also are you getting any codes and are there any stored?

New update runs solid now but push brakes and its very hard to stop damn near cant stop.
