Good evening,

Sounds like you have a low battery. Check the actual battery voltage with a voltmeter and also make sure the cables are tight and clean connections.

Hello,

This sounds like you could be having a problem with the Starter Motor Relay which is located in the right front inner fender well, near the battery. In the diagrams down below I have included a wiring diagram of your vehicle's starting circuit as well as a diagram of the Starter Relay location for you. Here is a link for you to go to on how to test a relay:

Please go through these guides and get back to us with what you are able to find out.

Thanks,
Alex
