I believe I determined that the fuel pump is bad. I pinched all the lines as mentioned, checked pressure on the inlet tube while disconnected from rail the check pressure directly from pump out of the tank. 21 pounds max pressure. I am sure that it was the correct pump when installed three years ago as my wife and I drove it at least 100 miles without problems but the I returned it to my friend, the owner and it sat for 2 1/2 years, We shall see when my friend buys his new pump. Than you all for your input.
