A timing chain or belt is worn so sloppy that it jumps a tooth on the sprockets creating loss of power and performance, jumping more than a tooth would render the engine inoperable and in some cases destroy the engine in an interference engine.
Your timing belt has probably worn out, or broken, and has jumped timing.
The timing chain or belt has worn and stretched to the point where it can jump over the gears/sprockets, in which case the engine would be pretty much powerless.
If the car won't start it is usually the battery, starter or could be the altenator. What are the symptoms when you try to start it, is there any power?
Check the timing in the caravan. It sounds like the timing has jumped, and the engine could backfire then not start, and could not even turn over.
Sounds like ignition spark knock which means the engines timing is off.Im not sure on this car if timing is adjustable But its possible the car jumped time and still runs.
I the Blazer will run then the timing can be checked with a timing light. If not, the there are timing marks on the timing gears that will have to be checked to see if the timing jumped.
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.
You will know if your car has jumped timing by the way it starts up. If the engine is slow and sluggish, it could be a sign of jumped timing. Also listen out for strange noises coming from the engine or if it backfires, it is likely that there has been a change in the timing sequence.
Incorrect timing, or timing has jumped.
no the car will not start timing has to be set again
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.
To fix the Pontiac Sunfire if it jumped time, the timing belt has to be replaced. Then the car has to have the timing set again after the belt is replaced.
This engine (3.0L) is an interference engine so yes, the engine could lock up if the timing belt jumped.
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.

Your timing belt has probably worn out, or broken, and has jumped timing.
