check engine light

I have a check engine lite on. Code states low fuel pressure in left bank. I have checked plug, wire, fuel pressure, and checked for vacuum leaks. any ideas?

Check for fuel filter going bad (clogged) I have ran into this on two different cars (customer's) and a new fuel filter cleared the problem.

Chuckster,
Changed fuel filter. It was restricted but did not solve problem. Any other ideas

Have you checked the fuel pressure at the fuel rail? there should be a schrader valve (like a tire) on the fuel rail for you to hook up a gauge. I believe you should have between 45-60 PSI. I am not sure the model and yr. your working on but it may have a fuel pressure regulator also, on the fuel rail where the fuel line enters. And did you clear the code after the fuel filter change?
