Check engine light - Code 5-1-1??? 900

Oy... that's a lot of possible causes.

The engine takes quite a few rotations at startup before it will catch... I've assumed this to be a defective fuel line check valve, and have been meaning to replace it. Could this lead to low fuel pressure?

Does anyone have experience with this code? Idle seems to be fine... perhaps the slightest hesitation just off idle, when I tip into the gas.

I'll do some more research. Thanks Dan
