My 2000 Toyota Townace with 2.2 liter 3C diesel won't start below freezing. Truck has 90,000km, about 30,000 of those on mixed fuel. For a number of reasons, I think it is the injectors. Mostly because I run it on 50% oil in the summer and I think everything else is fine. A set of new injectors isn't outrageously expensive, under $200 for the set with delivery. I have the time to mess around with it so I thought, "hey let's pull these things and clean them and see if it makes a difference". I've done a bit if internet research, I have acetone and a brass brush so I'm thinking I'll try it.

Any tips or hints? Will I regret saying it looks pretty straight forward?
