Sleep walker, thank you for the help, concerning fuel pressure lose. I hope the following my help someone else in need. FYI: I changed the F/P relay, even though the old relay had clean contacts. It was a good idea to replace anyhow. And there was power at the F/P relay. The fuel pump was the problem as we suspected, it worked on the bench, but that was because of using to many amps to test the fuel pump. I still wasn’t sure that was it until I tried it again on the car power, boy what difference.
I also didn’t realize the pump would only fire up as the car is being turnover on starter power.
I replaced Fuel Pump $ 189.00, Fuel Pressure Reg 42.00, F/P relay 26.00. And purge the air out of the fuel rail. Started right up, runs like a Mercedes S320 1995'.

Thank you again
