Hi there new here..Hope this helps. Try checking complete electrical starting system or scan computer to see if all electrical is in specs.

If everything is in specs and vehicle is running correctly there are many possibilities.

Check starter itself and check fuel pump pressure, also when vehicle fails to start note if it cranks but will not start most likely the fuel pump but only after pressures have been checked.

If it will not crank then listen for the 2 second priming from the gas tank, you may have to remove the gas cap to here this sound, then it most likely is the starter.
