hi everyone, my name is Joe im 16 and just bought my first fullsize truck its a 1987 gmc jimmy TBI 350. when i first bought it it ran awsome but as soon as i got it home 2 days later and tryed to start it, it wouldnt start it only cranks (but deffinitly has spark cause of a little starter fluid test!) it has been like this for a couple months now. i took a couple tests for voltage at the throttle body and nothing even when trying to start it. also the fuel pump will no longer turn on when the key is turned i dont know if the 2 problems are linked togethor or different. (if the fuel pump is riged up from the battery it will turn on) as you can see im not a mechanic but i also dont wanna halfass my truck so if anyone has any ideas or suggestions it would be greatly appreciated.
