Why would an 86 diesel Jetta stop running and not turn over in a matter of a day?

Maybe mine was bit different but when I started it, it was sounding odd. I drove it for a few miles and it just seized up. Had to replace the whole motor. The dealer would not tell me what caused it but I assume the owner before me did not change the timing belt, which i think caused it. I remember looking down near the left side of the engine and there was a broken shaft where the belt goes normally. This was a 1995 Passat TD Diesel Check for broken wires, especially ground wires,,,make sure no wires live wires are touching metal In my 86 Jetta the trunk light switch was defective and caused thelight in the trunk to stay on and kill the battery. I repaired it and all is good I would check you Battery if it don't turn over ,a Diesel engine has a very high compression and needs lots of battery tork to turn it over and batterys sometimes just die for no reason,it happend to me.

you could, but than you would have to change verything except for the block itself, so the cheaper option would be to get a drivetrain from a wrecked golf/jette diesel.

My best guess would be that it means you need to perform your regular maintenence

No. Iginition in a Diesel engine comes from compression and not spark. Once the Diesel engine is running you do not need electricitry to keep it running. However, modern diesel engines have computers controlling many of the functions of the engine and that would cause it to fail if there was no electricity. Old diesel engines did not have computers and would keep running even if your battry went flat because your alternator died. Just dont turn it off because the starter needs electricity :P

The engine would stop running. You would need to drain the gas tank. If the engine has been allowed to run since the diesel was added you would also need to drain the fuel line.
