Pull the starter and check the ring gear teeth for burrs and mashed teeth. Ensure that the new starter has the correct number of teeth on the pinion as required by the ring gear or you will have the wrong gear ratio for your vehicle. There are many engines that use the same starter motor but are differentiated by the number of teeth on the pinion. I suspect that will be why there is hard noise and kick back as that is the out of mesh gears trying to work

SOURCE: hard to start chevy 350 vortec

You will need to do a fuel pump pressure leak-down test, the pump must not loose more than 5 PSI overnight, u will need a cheap fuel pressure test guage, the test port is on the fuel supply rail to the injectors on the intake manifold, it looks like a tire valve but metal with a plastic cap on it, u may be able to borrow this guage from Kragen, Autozone or a parts store like them, if not they are very cheap, less than $20 US. Run the engine with the test guage hooked up, turn off the engine and then check it in an hour or so, if it drops more than 5 PSI then u will need to replace the fuel pump in the gas tank. One note make sure the connection for the guage is tight with no leakage or the test is invalid

SOURCE: my 99 gmc suburban won't start. the starter

Need more info -- but I will try to help you as much as i can. If the starter is not turning -- you will have to ck your cables from the battery to the engine. So you need to ck the positive or red cable to the starter, this one is the large wire on the starter soleniod. Ck it all the way to the starter, from the battery and any conections in between. It must have a good conection and be hot same as the battery voltage (+12.+dc). You will have to ck the ground or black cable conection to the frame and also the engine block. The battery grounds to both locations. You have to have a solid conection to turn the starter on both of thses wires. Ck these wires and the conections to the starter and the engine. Next problem could be a bad flywheel.  The flywhee has teeth on it like a gear- and the starter has teeth that mesh into these teeth to turn the engine over. The flywheel could be damaged in the area that it is in now at rest, so the quickest way to find out is to turn the engine over by hand. Using a ratchet with the right socket fitted (to the crankshaft end-- the largest pully center bolt) turn the enging 1/4 turn and get the ratchet out of the pully and try to start the engine, if it turns over and trys to start you have a bad flywheel my friend.
