The presence of fuel does not mean that it is at the appropriate fuel pressure. Test the pressure and let us know what the gauge reading is.

What would you use to test it? Never done this before so I'm not sure what the procedure is. Fuel pump was replaced a little over a year ago, when the engine is turned on you can hear the pump turn on. YES I am aware it may not be shooting enough fuel out. Just letting you know what we do hear and what we dont. It will shoot fuel into the carb but doesnt' seem as if its getting to the injectors.

A fuel pressure tester... Get yourself a fuel pressure tester and screw it onto the fuel pressure test port then put the key to the RUN position. Pressure should be ~60psi.

Ok thanks.. I'll check with some buddies n see if they have one we can borrow. I think he's out checking the injectors now.. and all of the connections to see if he may have forgotten to plug in something.

As soon as I know results I'll get back to you..

Thank you for the suggestion.
