Engine Mechanical problem
1999 Mercury Sable 6 cyl Front Wheel Drive Automatic 165000 miles
Hi, my Sable had been running rough(hesitating, rough idle and stalling) and finally ran so rough that I was barely able to limp it home by keeping it in neutral and revving at stop lights to keep RPMs up. I suspected a fuel issue and have checked the static fuel pressure and am getting 18 psi, which is well below the 37 to 45 psi spec in the manual, and I can hear the fuel pump. However, I was unable to perform the associated tests with the fuel regulator and vacuum lines because I cannot get the car to start at all now. The car does crank and the the fuel pressure shoots up to around 34 psi and I can smell gas, but still no start. Is there anything I can test that will isolate the pump, an injector or a regulator as the culprit without the car running? Thank you for your time.
have the same problem?
