Looking at your original problem post, the answer seems obvious.  In
trying to flush out your fuel system you pressurized the fuel lines with
the engine stopped and key off. After a while the intake manifolds were
filled with fuel and fuel dripped from everywhere.

The likely cause is a leak in the fuel pressure regulator diaphragm. The
fuel pressure regulator connects to the intake system with a vacuum hose
so the fuel pressure can compensate for changes in engine vacuum. The
regulator can leak internally and raw fuel can go down that vacuum line
and flood the intake.

Pull the vacuum line off the regulator and plug the hose. Now turn on
the key so the fuel pump runs for a few seconds. There should be ZERO
fuel dripping out of the vacuum port of the regulator. Start the engine
and make sure there is still ZERO fuel at that port on the reg.

This is a common failure and will cause the engine to run way rich and
likely stall out quickly.

The only other source that should be able to cause gross flooding of the
intake is the injectors. Not hard to check if need be.
