Did you check fuel pressure regulator?

1 out of 1 people think this is helpful.

yes i took it apart and cleaned it . whats weird if i unplug the injector on the left side the truck stays running on one injector .if i unplug the injector on the right side it dies the fuel quits coming out of the left injector and right

I should also add i sprayed carburetor clear around the outside of throttle body and vacuum lines no leaks any where
