Engine sounds i just replace my starter and when i start the car i get a metal grinding sound.

sounds like the starter and or ring gear have been stripped , need to have starter remove to inspect both

Many times a bad starter motor makes noise like clanking, clicking or grinding when crank the engine. Replace the starter. Sometimes, if the starter motor is grinding the gears on the flywheel, the engine will have a metallic grating sound when you first crank it. This type of starter noise is normally indicative of a starter motor that is worn and about to fail. If you do need to replace your starter this site looks like it has cheap prices, free shipping and great reviews http://www.buyautoparts.com/starter.htm

Are you saying the starter is grinding but the engine is not cranking, or the engine is cranking and making noise and not starting ?

You need to have your flywheel: replaced.Your starter motor engages against the fly wheel at the back of the motor. Every time your motor stops it tends to be in the same few positions (just the way things work) so there is more stress on some parts of your fly wheel than others. Because of this the teeth wear out on the fly wheel which means the starter can correctly engage on the fly wheel which is the grinding noise.

The starter is bad, the drive that extends out to engage the flywheel has failed. If this has been going on for a long time, there's a chance the teeth on the flywheel are damaged, this should be checked when the starter is replaced.

try shimming the starter , it sounds like it is a tiny bit to close to the flywheel and is binding, causing a tinny or metal to metal sound.
dosent sound like it needs a very thick shim .probably no more
than a thousands or two. hope this helps

Good indication of a bad starter. Is it just clicking or is it a grinding ugly noise?. The second is definately the starter.

1.The shims go between the starter body, and the engine block. These are installed to space the starter drive gear, away from the flywheel. They are only used if needed.

2.There is a gap that you need between the starter gear teeth, and the flywheel teeth. This gap should be about 3/32nd's of an inch, to 1/8th of an inch. With a flashlight, and a ruler, measure between the outside edge of the starter drive gear teeth, and the outside edge of the flywheel teeth.

Too close, when starting the vehicle it sounds very metallic, and like you're grinding corn.
Too far away, and the teeth don't engage properly, and you'll KNOW it! Sounds like a metallic 'zing', as the teeth skip. (Also it won't be long, and you'll be replacing the starter drive, and the flywheel!)

That sounds more like a dead battery than anything else. The bendix, the bit that engages the starter to the flywheel, usually goes bad a bit more slowly and causes more dramatic persistent grinding. A bad starter is also possible, as are bad battery cables. The starter mortor and bendix are both replaced when you install a rebuilt starter. If a jump start doesn't solve the problem, and connecting a jumper cable directly from the + battery terminal to the starter motor doesn't help then replace the starter. If it does help, then the problem is probably the battery cables.

If the hard grinding noise is a metallic sound only when you start it, sounds like your starter bolts are loose or the starter itself needs replacing. fuel pressure doesnt cause any particular noises like that. If your fuel pressure or pump had problems, your vehicle simply wouldnt start
