My dad is the original owner of a 90 CRX HF. He drives it very little; the car has just over 50,000 miles on it. He's always had it maintained at the local Honda dealer according to schedule--it's a very well-kept car. He recently told me that on occasion, the car won't crank, acting as if it has a dead battery. Through trial and error he found that manipulating the throttle body by hand seemed to unstick something, as the car starts every time after he does that.
I've tried to help him with it, but he lives in CA and I live in TN, so all I can do is make guesses about what he tells me over the phone or via email. He's also not very knowledgeable about this sort of thing. I told him how to clean the throttle body, thinking something might be causing it to stick. That didn't solve the problem. I have no idea why anything related to the throttle body would cause the starter not to crank, but I don't have much Honda experience. Does anyone have an idea what would cause such a thing?
