When troubleshooting a vehicle, I like to start with the simplest explanation first, your truck symptoms sound like enough fuel isn't getting to the chamber. Remove your fuel filter, check and see if it is clogged, you'll need to pass some air through it. I recommend not putting your lips on it (gasoline is poisonous!), but taking a rubber hose or straw of some sort and using that to blow air through it. If there is little to no resistance that isn't your problem, if there is quite a bit of resistance *you'll know*, then replace the filter and hopefully that will solve your problem. If not, i can think of other things to check, but I think this should work.
There are many possible reasons why your 97 Jetta will not start. This may be due to mechanical problems in your engine, battery problems or problems with the wiring system among others.
The electrical system
The compressor is located on the front passenger side of the engine compartment just in front of the battery. (man, have we had problems with the whole suspension system!)

I would suggest getting a GPS system installed by a professional, as it is easy to do it wrong and have dead battery problems. That can be pretty inconvenient.

Dead cell in battery, loose of corroded battery connections, or the charging system on the mower engine is defective.
Age of battery Battery will not hold a charge (check with a volt meter) A fully charged battery should read approx. 12.8 volts (without engine running) If charging system is working properly reading should increase to approx. 13.8-14.2 with engine running. If voltage does not increase with engine running could be a problem with charging system of battery is defective and will not take or hold a charge
none, it's when you shorten the gas system that causes out of battery problems.
The reduced engine power light means that there is a problem with the battery or power system. It almost always means a battery connection issue.
Have the charging system checked. The light comes on when there is a charging system problem. it may be a battery, alternator or a battery problem.
A few problems you would expect with a used Volkswagen Passat are problems with the fuel system, braking system, and engine.
