It could if the valves made contact with the pistons in an interference engine.
This engine (3.0L) is an interference engine so yes, the engine could lock up if the timing belt jumped.
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.
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.
1st you have to repalce the timing chaing and gears. Then, you can set the timing correctly.
Very likely
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.
Check engine timing, sounds like timing chain might have jumped a tooth
Check the 1989 Honda Accords timing. If the engine has jumped time then the engine will buck and sputter.
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.
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.
No oil bad bearings. If it's an interference engine and the timing belt slips or breaks the pistons can slam into the valves causing damage. On_mitch
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.
