1990 YJ-Fuel Problems, Won't Start

I just replaced the fuel pump and filter. When you take off the air handler and look at the injector, it is not dropping any fuel out of the injector, but I can hear a small gurgling sound coming from within the throttle body.

I the Jeep has been sitting it will crank right up, but if you turn it off it won't start. It seems to be flooding out.

Might be a fuel regulator? Anyone have any thoughts.

When you start it cold does it run and idle okay as long as you don't cut it off?

Nothing is foolproof to a sufficiently talented fool.

It may be in the carburetor "float." There's two brass looking bulbs inside the carb that should move up and down when revving the engine. They might be full of fuel and not moving.
