2007 dodge ram 1500 4.7 flex fuel engine
The truck always cranked rapidly and started until a few weeks ago. Now it labors a few times then cranks as before and starts. Cables are fine, no resistence with multimeter. O'reilly guys tested the starter and alternator on the truck and say no problems there but their tester clamped onto the battery posts, can that properly test the current draw? Are the o/reilly guys wrong? Do i just need a new starter?
