Before I drop $120+ on a new Bosch cold start valve or travel to a junk yard that has one, I want to see some opinions. B21f, cold start hesitation, mostly wants to fire right at the first turn of the key, but sometimes varies. At first I though it was the warm up regulator but after fiddling with that it seems to be just fine. When I crank the car I'm getting power THROUGH the plug on the cold start valve so (which is important because I believe the thermo time switch makes the ground on the negative side?) but the injector on the manifold never fires. Nothing, even when it hasn't run in a week (thinking about the thermo time switch here)
