Starter has begun to fail last couple of weeks. Raise hood and tap starter solenoid gets me "started." I do a lot of deliveries every day and understand this puts extra strain on it. Had my mechanic check it out and he can't find anything wrong. It starts strong in his shop and road test. With me, it is hit or miss.
New Battery less than one month old. Mechanic tells me all connections very secure; getting plenty of cranking amps; everything charging up as it is supposed to. He's baffled at this point.
Suggstions welcomed. Had previous starter replaced roughly 3 to 3-1/2 years ago. Many thanks.
