The fuel injectors on my truck are not working. I am getting fuel to the
throttle body, but the injectors only dribble gas out instead of spraying
gas. I have changed the fuel injectors and the electronic control module
with no help. Please advise on other things to try. Thanks

How much pressure do you have at the throttle body?

I'm not sure what the pressure is. Please tell me how to check this and
what the pressure should be. Thanks

Pressure from fuel pump should be about 13 to 17 PSI and at the
injectors after the regualtor in the TBI unit, it should be around
10.5 PSI give or that a bit.

Have you checked the fuel pressure at the injectors?
