Old Truck, starting problem, like battery and then
Weekly I use this old truck, '88 Chev, that has curious starting behavior.
First time I try to start it turns over about three times Whirrr, whirr, whir and nothing like a dead battery.
Then, about three hours later, if I try again it suddenly starts.
What can be causing an old truck to sound like it has a bad battery and then three hours later start without hesitation?
