NA won't start hot, narrowed it down to fuel issue, HELP

Ok,

Here we go, I hope this time I have found the potential problem.

Started the car cold, went for a drive, got it up to operating temp.

Came back and turned it off, same thing car turns over but won't fire up.

Pulled off the fuel line to the fuel rail and also the return line.

Both fuel lines now disconnected, no fuel pressure to the fuel rail.

Cranked the engine over and fuel came out of the fule line from the tank with reasonable pressure, and guess what the engine started and ran for about 10 seconds until the fuel rail was dry.

Hooked the fuel line back up and it would not start.

Took the fuel line off and it started and ran for about 10 seconds again, did this over and over again and the same end result, runs with no fuel pressure at the rail and won't run with the fuel line connected.

Any ideas?

Howdy,

I'm certainly no expert but it's usually one of these two when it's "heat" related:
