The car is hard to start but once started it runs great. The guys at the parts store says it's the knock sensor.

A knock sensor won't cause a hard start because it adjusts spark timing after the engine has started.Checking fuel pressure may be a good starting point.When was the last time this car saw a tune up including filters and plugs.Are there any stored codes?Press off and warmer and hold until the dash does a bulb check.Pcm should be displayed on the driver information center.If you press fan up now it should display powertrain codes,press up for the next and so on.Then post them here.Turning the key off will leave diagnostic mode.

Replace the fuel filter and if it's still not right check the pressure.Did PCM come up when you checked for codes?
