I can't get fuel to my injector and the fuel pump doesn't come on

What is your question?

Sometimes when I'm driving my truck down the highway it'll sometimes smother itself out like it's not getting either enough fuel or its getting to much air idk and every time I try to crank the engine I have to loosen the fuel injector I need some help

What makes this problem better or worse?

Nothing has helped

How long has your 1990 Chevrolet S10 had this problem?

Loong time
