Depends on mileage and condition.
is it running out of fuel?
YES!
To replace the 1990 VW Jetta water pump you need to have a new one. By using the tools in the tool box, carefully open the old water pump and replace it with a new one.
It could be timing or a bad distributor cap. There are other possibilities as well but those are the two best candidates. Check the Spark plug wires. I had the same problem and it was due to corroded rubber insulation on my wires. resulting in electricity arcing over to the engine! this was not good, but a change of the wires was all it took to fix it!
The 1990 VW Jetta turn signals will not work when the ground wire is broken or corroded. The turn signals may need the lightbulb's replaced.
