Fuel Pressure Problem help!
Recently I dropped and emptied the tank, changed out the fuel pump and fuel filter for my 2001 stock GT. The car had been sitting for about a year and a half and wouldn't start until I changed out the pump. It held idle but, ran rough and when I put it in 1st gear the motor would die. The Ford dealership said the codes indicated: 1) Misfire 2) Vacuum Leak 3) Fuel Pressure. So they checked for the Misfire and couldn't find anything; did a smoke check and couldn't find a vacuum leak; checked fuel pressure and found 29psi, which is extremely low. They want to change out the fuel pump for $1,100.00 but, told me there's no guarantee it's the fix. Also, they did a "ring check" and said all cylinders compression is good. My question is: 1) could the FPDM be defective, or 2) I found out that the fuel tank filler neck attachment and screen were broken off in the tank this attachment is at the end that is in the tank. Apparently the pump must have been changed once before. I did change out the grommet however, i didn't think to change out the filler neck because I thought the device at the end was used to prevent siphoning of the gas. I also removed all the broken pieces from the filler neck that were in the tank before I reinstalled the new fuel pump. Could that missing attachment at the end of the filler neck be causing the fuel pump to not deliver enough pressure?
