Yes, we have been down this road before just not far enough. Daily driver, running fine-go in for lunch, come out and no start. Have changed all the plastic lines, fuel shut off (it is working) and crank position sensor. Am getting fuel to the injector pump and the overflow line has fuel coming thru it but if I take off an injector line, there is nothing and if they ain't squirting-it ain't gonna run.

Some interesting things: hit it with ether and there is really no response at all. It changes it's tune a little but no interest in firing. Pull codes and there are zero issues which I find kind of weird in itself.
I keep coming to the injector pump but why would it be running fine and all of the sudden not work? Don't these fail gradually over time (as in it may get harder and harder to start)? I believe to glow system to be fully working as it draws current for the right amount of time but, again, I am getting nothing out of the injector lines.

I'm stumped. It's a stunning car and would be even more stunning if it ran.
