Joy, sorry to hear of your troubles.
When a WBX simply won't go, the problem can be narrowed immediately to
one of two things - Fuel or Ignition.
Ignition test. Pull a plug wire from a plug, or use a test light(I
prefer to use a test light which I carry in my tool kit for my van) ,
hold it next to the metal on the engine and turn the engine over. If it
arcs a spark, re-install and go to the next test.
Fuel test. Disconnect the fuel line on top of the engine at the "T"
where it splits and goes to the fuel injectors. With a helper, turn on
the ignition but do not turn the key to the start position. The fuel
pump will energize and should pump a stream of raw fuel from the fuel
line. Be careful not to have the line anywhere near your eyes. The fuel
pump will pressurize that line substantially and there will be a good
stream of fuel. All it takes is a few seconds to see if you have a good
fuel flow in the system.
These little test are simple enough and will isolate your problem to one
system, making it easier to begin the search for the real culprit.
Since the engine started again at least once, I would suspect a fuel
problem, but the way the systems use electronics, sensors, etc, this day
and age, it could easily be either system causing the problem. For
example, a faulty O2 sensor could cause the ECU to try and run the
engine over rich, resulting in a flooding condition, which would make it
hard to start, even with good spark. But being sure you have good spark,
and fuel flow, is the first place to start.
If you have a Bentley, it's worth a read on such matters. I have over
time become quite adept in doing all my own maintenance, with the aid of
the Bentley book. This development came as a necessity since fewer and
fewer mechanics are willing to work on Vanagons. It's really kind of
silly, the attitudes I run into, because the Vanagon is one of the
easiest machines to work on in my book. I've had other vehicles - Jeep
Wagoneer wide track -, Impala, Silverado Pickup, to name a few, and they
were a serious PITA to work on. The van is easy by comparison.
Good luck.
Regards,
John Rodgers
