Hard starting when cold, runs fine - Toyota Yaris Forums

Just an update.

I replaced the fuel filter unit.

I used an aftermarket unit. Wesfield WCF232.

The parts that I needed to keep were the fuel pump, something that I think is the pressure regulator, the screen that keeps the very course particles out and the float switch.

The problem has now dissapeared, the car starts and runs fine. It still has a slight hesitation and then surge off the mark as it did but not as bad.

It has always been there and our 2015 Yaris that we purchased from new also does it but not as pronounced.

Maybe it’s just me.

It has been only two days but it has started every time so far. If that changes, I will post another update.

Is replacing fuel filter a DIY?
