I usually flip the lever to lock the head onto the valve, should I try not touching it next time I pump that tire?
Maybe try flipping it the other way? Idk I'm not an expert but for some reason my old pumps you flip the lever down 90° to lock it but on my newer pumps you flip it straight (so it's pointing the same direction as the valve, towards the center of the wheel).
When using a new pump I just keep flipping it differently until it works, and I generally don't have problems with presta. Not sure if some pumps make you flip it differently depending on the valve type - it seems like they all invent their own way to support both so it's confusing.
I don't do that. That might be a shrader thing, but I think it just bumps it off the presta valve. You also might need to open the valve all the way until it won't turn anymore.
