Re: Starter won't turn over engine
I know it sounds dumb, but by turning over, you mean that the engine turns but does not start? Or, that the starter turns but the engine does not turn (spin with the starter engaged and running). If engine turns with starter, check spark & fuel. If starter turns and engine does not, check the teeth on the flywheel. if any are missing or worn off, it will give that problem. If starter engages but engine seems to be "locked up", remove spark plugs and attempt to turn it by hand. Any coolant on plugs indicates a blown head gasket or cracked cylinder head. If engine does not turn by hand with plugs out, likely you have a bearing or other "lower end" problem.

It is not a problem of sensor as it is not showing any dashboard light, neither it seems to be a problem of battery as battery gets charged after driving if the alternator is working fine or otherwise it won't start at all after overnight standing. It could be a problem of starter solenoid as it has copper windings and when the copper winding gets old it functions intermittently. I am sharing a video that will explain it better.
The 1st thing i need to do is clarify what you mean by "won't trun over" do you mean the starter motor spins the engine and it will not fire up or that the starter doesn't trun the engine over? If the starter doesn't turn the engine over do you hear a clicking coming from the starter solenoid when this happens? If so replace the starter solenoid the heavy electrical contacts are burned.
I'm not sure that your starter is in good condition .You have to pull your starter out from engine . Ensure the safety dental starter and the engine . If you find that the dental starter Moving north and right . You have to replace the starter . good luck , and let me know .............
If the engine is running when you try to use the starter, it won't flood the engine, it is already running. What happens is the starter gear tries to lock into the flywheel and this causes the starter to spin faster then it is supposed to. It is likely you damaged the starter and it needs replaced. You can remove it and have Auto Zone test it for free.
Sounds to me like the starter or starter relay, OR did you check all the fuses? When the starter doesn't click or turn over the engine it is likely a problem with it or the power supply to it. Start with the easy thing. check the fuses, then the relay.
The P0300 is usually caused by something other than the spark plugs or coils. A fuel/oxygen sensor can cause this code. I would say that doesn't have anything to do with not starting.
It sounds like the starter. Take a rubber mallet or a small hammer and beat the starter a few times not really hard like it owes you money, but hit it good. If the car starts after this your starter is stuck and needs to be replaced. Now this might not work, the starter can be so bad that nothing like this will help. Take it off go to your local parts store and they can test it for you. There should not be a fuse anywhere on the starter wire. O yeah make sure the battery is good and charged up. A low battery will do this too.
first unhook the battery, remove the air cleaner box and ducting to the throttle body, you will see the 2 bolts for the top. you will then need to go under the vehicle(make sure the vehicle is properly supported), and you will see the bracket between the engine block and the intake manifold, remove it.the starter wire does not get removed from the starter, it has a connector about 4-5 inches away. disconnect it there. disconnect the battery cable from the starter, remove the last bolt and it will come right out. all in all it takes about 30 minutes. most places will charge a "core charge" on a product like this. dont be suprised, however when you return the old starter you will get your money back. let me know if you need further assistance.
If your starter is turning but not turning the engine over then the "bendix drive" in the starter needs to be replaced. This requires disassembly of the starter once it is off the truck. Usually the best bet is to replace the starter unless it is new in which case the bendix is probably defective.
It's a remote possibility that there may be damage to your ring gear on the flywheel, but that can be checked when you have the starter off the truck. Just look at the teeth in the starter hole and make sure none are missing or chipped or narrower than the rest. They probably are but it doesn't hurt to check. Hope this helps.
