Question about Chevrolet Cars & Trucks
Never gave a clue. just went to start and it felt like it was out of time then the starter chewed up the flywheel
Could be internal mechanical failure in the engine, broken chain, bent valves, etc

Hello, I would make sure that your car is not one of those half year cars becuase two differn't starters may be offered for the same year of car. Also, I would check and see if your battery has enough CCA's to power your system. The only other thing is to turn your crankshaft with a breaker bar to turn your flywheel to possibly get a fresh area of teeth on it. If none of this fails it's as simple as just replacing the flywheel. If you did a bench test on the starter and the bendix engaged that is good. Buying parts from an Auto parts store does not gurantee the part is good and that the bendix engages the full distance to turn the flywheel. I would try to find a mechanic who rebuilds starters to make sure that the bendix is engaging fully. I hope this helps you!

SOURCE: car will not crank
Check battery voltage should be 12v. Have battery load tested. If good recharge, then with a voltmeter across battery terminals try to start engine. If battery voltage drops below 9.5v starter has failed.

you do not say that you got the vehicle in this condition so i am guessing that everything worked just fine for a while then all of a sudden it did this. it would be nice if you still had the starter that did work when you got the truck but i'm sure you turned it in for a core several starters ago. it may have had a different number of teeth on the gear that spins out and engages than the ones you are buying at the car parts store. if somebody changed the flywheel at some point in the life of the truck and used the starter that went to that flywheel that would cause the situation you describe. the only other thing i can imagine is the spacing on the starter, like maybe it needs to be shimmed to work properly. the way to check that is with a feeler gage after you bolt the starter up, but that is mostly general motors vehicles, probably not your truck. here is a way that you can check to make sure you have the right flywheel for your truck: get a paint pen or something that makes a mark you can see on the metal of the flywheel. now with the starter off get under the truck and make a mark on a tooth of the flywheel that you can see where it is when you start. oh yeah, you will need some help to do this. let the tooth you mark be number one. now have someone rotate the engine slowly (you might disconnect the coil so you don't accidentally start it, but you probably won't) and count the teeth on the flywheel, till that number one tooth comes back around. when you know what the number is on your flywheel call a parts store or the dealership and keep talking to people till you get somebody to tell you how many teeth it should be for your truck. if it doesn't match what you have then you know where the problem lies. at that point you can either replace the flywheel or figure out which starter goes to the one you have. if you already have the right one then i would check the tooth clearance. you should have .020 inch between starter gear teeth and flywheel teeth with starter fully extended. to check this you will have to connect the battery but loosely, bump the starter switch to get the starter to spin up and yank the battery negative while it is spun out. you can get the .020 check gage at a car parts store. hope that helps

Does the starter motor turn the engine over but you do not get any ignition (the engine fails to fire). Sudden poor acceleration and failure to start point to an electrical problem. Take out the plugs and check the spark quality on each one in turn. Bad spark means bad coil(s). If sparks are good then the timing is maybe wrong and this then points to either the crank sensor or the cam sensor as at fault. At 10 years or 100,000 miles it is worth changing these sensors anyway as they are prone to fail with age and heat. Next clean the throttle body interior thoroughly. Check all vacuum hoses for leaks.
