Message	When I turn on the key fuel pressure rises to 35 psi and holds steady till I start it. When I do, it fires up with no problem, sounds like it's going to keep running, but only for a second or two. I then see the fuel pressure start to rapidly drop till it stalls, and then reads 7 psi. Trying to start it then, without recycling the key, won't even hardly make it fire, much less start, and the fuel pressure just sits there at 7 psi. And when I do fully recycle the key it does exactly as above. It's like the ECU is shutting down the fuel pump. I don't know what's going on.
