Throttle body or fuel pump?
I found out the other day that my K5 wasn't getting gas to to the throttle body. I replaced the fuel filter and one of the lines and that didn't end up helping. I'm goin to try and replace the sending unit along with the pump while i have the tank down. If that doesn't work, then what else could the problem be? now i'm getting frustrated. and i need help. Could it be the throttle body or something electrical. Any ideas are greatly appreciated. thank you

Re: Throttle body or fuel pump?
Do a fuel pressure test before you change out parts.
Are you saying you are getting not fuel out the TB injectors when running?

Re: Throttle body or fuel pump?
upon messing around with things i noticed that there isn't power going to the fuel pump or sending unit. Is hard-wiring the pump to the fuse box advisable?

Re: Throttle body or fuel pump?
Don't start fucking around with the fuel pump wiring, you are looking for a fire.
Remove the inlet line to the fuel filter and see if fuel comes out when you prime the pump.
