Mine did the zero fuel pressure thing but still ran. Changed out the lift pump and still no pump action. No power to the pump and no obvious reasons why so I assumed the driver was toast. Found a switched ignition only power source in the fuse box and powered the lift pump from there. There is a potential safety issue with the pump running with the ignition on regardless of the engine running or not. Bleeding the fuel system is a snap tho with the constant flow.
