Whats the correct fuel pressure on a taurus 2000

The PCM - engine computer will energize the fuel pump relay for two seconds with the key , When cranking the engine the PCM will only energize the fuel pump relay if a crankshaft position input is seen . An testing fuel pump pressure should be done with a fuel pump pressure gauge only .

Ford equipped the Mustang SVO with 30-lb per hour fuel injectors in 1984. This was lowered to 30-lb per hour in 1985.

I would start with the intake gaskets. this gaskets are a common problem and would cause the lean condition and the misfiring and also before that even i would put a fuel pressure gauge on it to make sure the correct fuel pressure is being sent to the injectors, i weak pump can also cause this problem, starting witht the intake a smoke machine would be very helpful to pinpoint a gasket leak or using a scan tool and watching your fuel trim values while spraying throtlebody cleaner around the intake and seeing the values and if they change or the engine speed chages, this is where i would start. good luck and have a good day.

Hello Melita.

The fuel pressure for the Taurus;

Engine Running 240-310 kPa (35-45 psi)
Key ON Engine OFF 255-310 kPa (37-45 psi)
There you are as asked, thank you for using FixYa.

sounds like you are running lean , i would start by changing the fuel filter and check for fuel pressure using a fuel pressure guage at the shrader vavle on your fuel rail, if your fuel pressure is not above 35psi when you cycle your key on and you have changed the fuel filter i would recommend changing the fuel pump,

where is the fuel pressure located on the 2000 ford taurus exactly?

Have you checked the fuel pressure when running?

Is the fuel pressure correct?

Perhaps your fuel pressure regulator is bad, or the fuel pump relay is going bad.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

General rule is 32, not any lower than 28. if it is, fuel pressure regulator is bad, or clogged fuel filter, or bad fuel pump, etc.

THE ONE NEXT TO THE FIRE WALL IS THE CORRECT ONE.YOUR SERVICE HOSE WILL ONLY FIT ON THE LOW PRESSURE SIDE

fuel pressure at the fuel rail test port should be at least 44 PSI, when u gun the engine it shuld go up very quickly, it should never drop, if it does the fuel filter is either plugged or the pump is defectuive
