Smile 1993 Ford Ranger Problem

This is a continuation of 8/15/09. Well, things have changed now. Yesterday was the first day I used the fuel pressure guage. Yesterday, sometimes the pressure would go up to 10 PSI when I first turned on the key, not running, but the truck would start every time. Right now it's very different. I did what you asked me to do. When I turn the key on this time, the pressure shoots right up to 40PSI. The fuel pump is not shutting off this time. It just keeps running and when I try to start the engine, it doesn't start. The engine just keeps turning. It almost sounds like it is not getting any fuel. After literally minutes the fuel pump finally stops the fuel pressure drops to 31-32 PSI and the truck starts with no problem. Other ideas? Thanks!

1993 Ford Ranger

The engine is a 6 cylinder 4.0. It just seems to have a hard time starting. The 40 PSI goes to 31-32 PSI as soon as it starts. I disconnected the vacuum line to the regulator and the pressure goes up. Could it be getting too much fuel?? Thanks!
