Hi, i have a 1987 chevy silverado 4x4,with a 350 fuel injection engine. Last time it was running was when i was driving and it was acting like it had no gas and wanted to start back up,but it was filled with gas. It died a lot befor,but now it wont even start up. I am trying to restore it and i need to find the problem.Only thing i can think it may be is the fuel pump,relay,or electric modulator.(what do i need to fix and how can i test anything to found out the problem.) If you have an answere it would help a lot.
