I need to check the fuel pressure!

On a 2004 Neon, but I can't seem to locate a diagnostic port for the pressure gauge. Any help?

Anyone? Bueller? Bueller? Anyone? Bueller?

I can not help much.
But on ones without a test port you may need a adapter fitting with the test port fitting made in it.
Tool dealer or some parts places should have something.
They also come with the import and higher end fuel gauge kits.
The neon should have some plastic fuel lines with the quick coupler fittings.
If you can get a adapter that will couple into the plastic line at or around the injector fuel rail/or throttle body.
Good luck MT

Thanks, I will look into that. The fuel rail on these cars, according to a manual I checked, normally has a diag Schrader valve on the end opposite the fuel line. Murphy's law applies here and this car has a rail that is sealed on the end the diag port should be.

the port is at the end of the fuel rail opposite end of the fuel inlet hose its covered with a black plastic cap
