SOURCE: Grinding noise when trying to start car.

hello first thing you need to do is take your starter out the starter drive gear either has busted teeth or the flywheel does with the starter removed mark the flywheel with chalk crayon so you no were you started from look at the teeth good keep turning the motor by hand checking till you come back to the original mark you made if there are no chips or missing teeth look at the look at the starter drive teeth there most likely busted or chewed down replace the starter goodluck please rate

SOURCE: starter cranks and cranks but

This sounds like the fuel pump pressure check valve is defective, that is the usual cause of this long crank time issue, I am sure if you replace the fuel pump and filter the problem will go away. If you want to verify this issue have a shop run a fuel pressure leak down test, after the key is turned off the fuel press should not drop more than 5 PSI

Sounds like you have a problem with your fuel injectors, either they are working to much or not enough once they get warm....

Take it to a shop ant tell them you want the injectors tested.

SOURCE: After starting, the starter stays ingaged (GRIND)

shim the starter it sounds like it is staying engaged to the flywheel try shiming the starter
