Replacing the fuel filter is a bit of a hassle. If you could get someone to scan it with the Toyota service tool on cold start, if the filter is really plugged, you'd see it be lean, rather than rich, as it should be during a cold start.

Hi CTScott,

A friend of mine just got an X431 scanner so I asked him to help out. But he couldn't figure out how to tell if its lean or rich when he connected the scanner. Can you guide as to what parameter on the scanner to look for?

Is there any other way of telling if the fuel filter is plugged??? I really need to solve this starting issue. It's like as if the engine is gonna shut down but then it picks up after several seconds.....

Thanks
