Hi everyone, I'm not good with the tbi at all, I'm really hoping someone has a solution for me. I have a 89 s-10 4.3 tbi. The only way it will start is if you mess with the gas pedal. I can crank it forever and it wont start but if I floor it and let off it starts and runs fine. When I turn the key on or crank it over, the fuel pump wont come on, but when it does start I can hear the pump for a few seconds after I shut it off. I did a full tune up including fuel filter. I took the fuel lines off the throttle body, cranked it and the only way gas will come out is if I floor the pedal. Sorry for the long post I'm just hoping the more info given, the better the reply I might get. Thanks alot in advance.
