Technically cranking good and turning over are the same thing. I assume you mean cranks good but doesn't run. Two common causes: 1) Fuel: not getting any. Tank empty, fuel pump dead, pressure regulator bad, fuel line blockage 2) Ignition: none. Bad ignition module or other ignition component. Less common cause: 1) Timing: timing belt/chain issue. If the timing belt or chain breaks or hops a notch then you may find you have both fuel and ignition but with the timing wrong it can't fire when its not getting ignition at the proper (compression) time.
check battery
Cranks is the motor turning over, But cranks and won't start means either you no fuel or no spark or both.
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
If it just cranks and cranks and cranks then it's likely fuel pump. If it died and it won't turn over anymore, likely alternator.
Cranks and turn over are the same thing. It may crank or turn over and not start. If that is the case, find out if it needs fire or fuel and go from there.
If your Honda CRV cranks but won't turn over because the spark plugs are not getting spark, ensure the wires are connected. A loose spark plug wire can cause this issue.
My car starts but it shuts off it says ck engine
Timing belt?? If there is a section of the timing belt with no teeth on it, it might be turning till it get to that point, slipping causing it to turn over fast, grabbing enough to turn over normal, but would not be able to start because it is now out of time.
If your 1999 Ford Mustang cranks but won't turnover you may have a problem with the starter, the solenoid, or the alternator.
Could be a zillion reasons but the first one that comes to mind is fuel pump, assuming it cranks over but doesn't start.
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.
