Ok so when I turn the key to on without starting it, its supposed to prime the fuel rails and provide some pressure correct? If I just turn the key to the on position and push down on the shrader valve at the fuel rail, should fuel come out of the valve? If it is supposed to and nothing comes out, does that mean bad fuel pump or bad relay switch or still could be either. I am only getting the P0190 code.

Or should there never be fuel coming out of the valve with the key to the on position?

To reserect this thread I am having the same problem with my 2004 mustang GT. It will only start with starter fluid and then will run forever however if I do not use starter fluid it just cranks and cranks and cranks. In the run position I do not hear the fuel pump priming but strangely enough once I start it with starting fluid ithe fuel pump must be running because it runs for over 10 minutes.

i replaced the Fuel Rail Pressure Sensor thinking this was turning the fuel pump off at initial start.

I've the disconnect battery for days, etc. Nothing seems to work. I have 12 volts at the trunk crash switch and even bypassed it.

Any thoughts???
