Check fuel pressure with a mechanical gauge, let us know what it is.

Thank you: But there one problem there is no where to test the fuel pressure. You have to install a fitting in the gas line. I can smell fuel but the injecters are not working I think.

Check the vacuum line to the fuel pressure regulator for gasoline, if gas is present, the FPR diaphram is ruptured and would need to be replaced. This would let excessive gas in the engine causing a flood condition.
