      Hi Mr. C! A faulty starter, starter solenoid, relay, alternator, battery, crankshaft position sensor could make this starting problem. However, without the presence of your vehicle we would not be able to properly diagnose it, nor provide you with a 100% answer. I would suggest that you take your vehicle and get it thoroughly checked by a certified mechanic before buying any parts that may/may not solve the problem.
