If the battery turns the engine over as it should then the battery is good.
Starter won't crank over engine? Battery or battery connection issues. Starter cranks over engine but engine won't start? Being a GM product I would suspect fuel delivery problems (bad fuel pump).
if it wont crank the the starter is probally out but if it cranks and the motor doesnt turn either the belt is to loose or the engine is locked up
if the engine cranks.... then it is not the battery or alternator.... look at the primary electrical system and fuel injection
Sounds like you have a dead battery.
Try a new battery, or get a jump start. Sometimes there is not enough power in the battery to start the engine.
It cranks the engine over in order for it to start running.
Well it could be many problems.Does the engine crank, but not turn over?If the engine does not crank at all, or cranks slowly, it could be a problem with your battery. Check the battery terminals and wires.If it does not crank, and you believe your battery is ok, check your fuses.If the engine cranks, but won't turn over, it could possibly be your spark plugs, spark plug wires, distributor or fuel pump. The best thing to do is to get someone with moderate vehicle knowledge to do some basic diagnostics.
fuel filter... or throttle body
An engine which cranks but will not start is not receiving enough fuel or has no spark. A clogged fuel filter or bad spark plugs often cause this problem.
engine cranks over but will not start.
Bad or discharged battery, bad ground, dirty connections at the battery, or a bad starter.
Sounds like your battery may be very low; if it turns over slowly when it eventually starts turning, definitely try jump starting or charging the battery and trying again.
If there is enough power to crank the engine at a decent speed then you should see spark. Please test the coil or crank sensor if the engine cranks over at a normal rate.
On one had you say it cranks and then you say it won't turn over. Which is it? If it cranks, then that means it IS turning over but just won't start. If it won't crank then it is NOT turning over. We need to know which it is to determine what may be causing this. Repost this with a better description of your situation
Most likely the starter is "dragging" due to worn bushings. When the bushings wear, the starter will "drag" against the interior of the housing and barely spin, causing the battery to drain.
If the engine turns over (Cranks) it's fairly safe to assume that the battery and starter motor are fine. Internal combustion engines need three things to work. Compression, ignition, and fuel. Any one of which will cause trouble. Way too many variables to have a simple answer, given the information given! Good luck!
engine cranks but wont start means one of these things.. Air, Fuel, Spark, or compression
Check to make sure you connections are all tight.
you must first ck the engine battery system also you must ck the battery cables to be sure they or not dirty at the battery !!! if at all else fails take small hammer too the starter by tape on the starter and have some else turn the key to start at the same time if the engine starts the starter is bad !!!! the battery may need to be taken out to have it ck if so take the battery to a parts house like auto zone they ck the battery for free in most cases. If the engine cranks, but doesn't turn over, check your fuel pump. Your engine needs three things for combustion (assuming it is a gas engine), and they are spark, air, and fuel.
This is not a good descripton of the problem. Cranks? you mean the starter works? But the engine is not ? Yes, it stalled...and now it acts like it wants to turn over (cranks), but will not start. The starter does work. The engine will not fire up and run. The battery has ample voltage and amperage. Could an "overheating" problem cause this...wouldn't it start up after it cooled down if it overheated? Thanks for the help.
The battery may not be fully charged to turn the engine over fast enough to start. The fuel pump may not be pumping fuel to the engine.
Starter could be bad, neutral safety switch, wiring, engine could be locked up.
