Car cranks but won’t start. Turn off radio to listen if fuel pump switches on while the key is in the on position and it does. Not sure what it could be. Please help!

Welcome to the site.

What year is it, and how old is the battery?

Have you checked for error codes?



TSB 18-017-12 may relate to your vehicle:
