If the timing chain has jumped time, the vehicle will run rough or not at all. You will need to check the time with a timing light to see if it is off.
Sounds like the timing is out of adjustment, perhaps timing chain has jumped
You use a timing light to check the marks on the timing chain/belt.
Don't know what vehicle you are talking about but with most vehicles if the timing chain jumped you won't get out of your driveway. With the timing cover off, most chains and gears have marks stamped into them that should line up when the number 1 piston is at Top Dead Center.
Unless a timing chain is making a noise or has jumped a tooth, they need not be replaced. Timing belts need changing according to the specs spelled out in the owner's manual.
Check your timing. Is it possible your timing chain has jumped a tooth?
Perhaps timing chain has jumped
It will be noisy or may have jumped time. The only sure way is to remove the cover and inspect it.
It will become noisy and you will hear it. Also you may experience poor performance if the chain has jumped a tooth.
Your question is too vague usually when someone says that their engine has jumped time that means that the timing chain has jumped on the timing sprockets. If that is the case you would need to change them. If the distributor is out of time to do it right you would need to have a timing light. You would need a repair manual for the specifications to fix both of them.
Highly doubtful, the engine has a timing chain and the ignition relies on a crank sensor for timing. But if the chain did jump you could probably tell by doing a compression test.
Timing chain "jumped"? 1 or 2 teeth?
Yes, a broken chain or chain that is worn so bad it has jumped a tooth or 2 can cause the vehicle not to start.
