That'* what your post just did to my brain. I'm having a very difficult time understanding what you're trying to say.

Anyway, if a valve is leaking, I don't see how you ended up at the FPR? Let us know what tomorrow brings.

Ok sorry for the screwed post,having problems getting car to crank due to cold weather
but found that the scrader valve was leaking,so i replaced the valve,leak stopped.thought maybe was my problem,next morning same thing..seems like i can bump the starter and the car fires,if i just hold key down turning motor over and over
seems not to fire,could i possibly have a bad ignition switch?have changed the fuel pump,put on a different coil pack,changed ignition module..??

Nah, it'* fuel related. The fuel rail pressurizes when you first turn the key, and there'* enough fuel to fire it but not run after the injectors start to work.

Check the fuel pressure, filter right below the passenger side rear door, and it that'* not it, it'* probably fuel pump time.

Did you replace the fuel filter right in front of the tank of the passenger side?

It'* also not unheard of to get a bum replacement pump. Checked the pressure?

OK, this is geting me confused. So help me get it straight.

You said that your FPR was bad. Yet your fix was the schrader valve on the fuel rail.

Did you ever really do anything to the FPR? Have you rechecked your FPR? Take the vacuum line off at the FPR and look for fuel or fumes. Either will indicate a bad FPR.

From what I can tell so far, you haven't convinced me that you've resolved your fuel issue. A bad FPR can cause your symptoms and can also be dangerous. I suggest you re-address that and let us know what you find.

Also, if you are cranking, then why do you suspect the ignition switch?

Please answer all the questions above as clearly as possible as I am having a tough time understanding you. The more detail you provide us, the better we are able to assist you.
