no fuel to shrader valve

To be honest, I didn't think the FPDM was correctly ruled in/out.

I'm with you. It is not POSSIBLE for the motor to run with ZERO fuel pressure.

I am not certain there isn't a problem with the Schrader valve. Consider getting a value core remover and remove the value core. I really suspect there is something blocking the value and that is why you are not getting a good pressure reading.

If you could cycle the ignition with the core removed to force fuel through the open Schrader valve. This is to flush out the line. It will also verify the fuel pump is priming.

Also consider disconnecting the fuel line from the rails. Get a suitible container to catch the fuel spray. Have a buddy cycle the ignition and verify a good flow of fuel.

Go back to post #9 and see the procedure to power the fuel pump directly from 12 volts. This will make the fuel pump run at 100% duty cycle. For a test, see if that makes the fuel pressure jump.

in the beginning I did disconnect the fuel line from the fuel tank side of the filter and primed the pump with no results. i really don't feel like rollin arond on a frozen garage floor today. But Sunday i am gonna mess with it somemore and try some of the electrical tests which I have not a clue hat I am doing hahaha. It is pretty much a garage queen in the winter have had it for 3 1/2 rs and have only put maybe 11k miles on it. Burns you have helped me a bunch I appreciate all of it I am just real dumb when it come to the elactrical stuff. lol

i have been having some running issues myself and after going thru much of what u have and alot of what wmburns said as well for my car, it ended up being a bad Fuel Pressure Regulator. You may be getting just enough fuel in the system to keep the car running and when u press the gas pedal u get much of nothing for power. after reading all of this, DID U EVER TEST FUEL PRESSURE with a gauge??

Also get yourself a Haynes or Chilton book if you dont have one. It will show you where everything for the car is located and step by step on how to fix things.

Sunday when I did have some time to mess with it I found the Fuel pump relay fuse had blown when this happen I don't know. So I replaced it and it started the first time but would not start again. I cycled the key on and off about ten times and it stared but idled the same. While it was running I pressed the shrader valve and had no pressure so I am going to take the needle valve of and see what I find, If i get some pressure I will put a fuel gauge on it. I don't think mine has a pressure regulator it has a fuel rail pressure sensor.

It could be the FRPS I suppose I did pull the little vaccum line of while it was running and the rpm's dropped quite a bit I believe that is what is suppose to happen is it not?
