It starts Ok at first I arrive at destination and turn off. Then when I go to return it’s slow in starting

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. When you state "it's slow in starting", do you mean the engine cranks slowly and eventually starts, or do you mean it cranks and cranks normally but it does not start right away? If it's slow to crank, you'll be looking at the battery and it's state of charge and the ability to sustain a load. If the battery is low in charge but passes testing, you'll want to check the charging system to see if it is working properly. You must have a known good battery and good state of charge to properly test the charging system. If the vehicle cranks well but does not start, it would be important to check for spark, air and fuel in the proper amounts at the engine.
