There is no schrader valve in this vehicle. How do I check the fuel pressure? I am trying to diagnose a intermittent stall. Id like to see if my fuel pressure is dropping when the van stalls by bypassing the fuel pump relay and jumping 14 colts directly to the fuel pump. I know there is a special kit from the dealership for checking fuel pressure, but is there any other option? Has anyone made anything that will allow you to check fuel pressure with a gauge? Please help, I've been chasing this problem for too long now. Thanks

my 01 T&C has a shrader valve. very hard to find but it was there! follow all the lines and you will find it. Mine is under the air inlet to the intake manifold. Under the big rubber bellow running from the air filter to the intake. Take the hose off and check there? very hard to see under that intake hose!

You most likely found the Shrader valve used to test the evap system. Does it have a green cap? If so it is NOT for fuel pressure testing.
Gen 4 is when the rail ports were removed as a cost savings.
I chose this picture because it shows the evap port and the fuel rail port as well. It is a GM engine bay shot.

This is what I have made up for my van.

No, it has a black cap, I know where the evap one is, that valve is located under the Air Filter box. The fuel pressure shrader valve is under the air intake bellow coming from the intake manifold. Follow the fuel lines leaving the intake manifold, the chrome one, and about 6 inches later there is the valve! I have tested the fuel pressure from there before! 2001 T&C. I see you made yours, I wonder why I have one and you don't? Mine came stock

I have a 3.3, I have a fuel shrader valve 100% it's there! Stock! on the fuel rail. right after where the fuel lines exit the intake. You have to really bend and look under the intake air hose. The evap shrader valve is in another area under the air filter box.

My 2001 Caravan also has the Schrader valve in the fuel line, exactly as described above by Noxzema. The valve was eliminated at some point in the 4th Gen run (probably to save a few cents).

As a side note, the evap port that 1994 Sport mentioned above was also eliminated from the 4th Gens at some point.
