93 EV won't start

I have no idea what it could be. It lost power, like it ran out of gas, or the alternator went. Everything we've tested

Fuel pump
Altnator
Fuel filter
Fuel relay
Fuel injection
Battery

It's got spark, it's getting fuel, the timinb belt is fine.

But, it will not start. It turns over, it just won't start.

I've reached the end of my rope and thoughts would be appreciated.

Have you tried squirting starter-fluid (ether) into the intake manifold while cranking? If it will start briefly on the ether you have spark, timed at least close. Then you look for an injection problem. If it won't fire on ether it isn't getting ignition at the appropriate time.
Starting fluid is one of the oldest and best ways to narrow a no-start condition.
Just be careful: the vapor is very flammable, so keep yourself back from the intake in case of a backfire.

Just to clear misunderstandings. Was any work ever done on the car before this happened?
Fresh in mind is a car that was towed to my place a few years ago. He had called and said his car would not start. I used an hour to try to start the car.
When I noticed some fresh gasket compound and called the owner who could tell me that his neighbour had changed the timing belt.:)

no work, well, we've replaced bad relays, fuses, and the flasher. But that was months ago, it's run amazing for the last year. Then suddenly, it just died. It has spark, it's getting fuel, the timing belt is not broken. All the relays, injectors and fuses are fine.

Is there a posibility that the timing belt has jumped over a tooth? Have you checked compression?
I would try to eliminate the timing and the compression before proceeding.

This sounds like the hall sending unit to me. It is located inside the distributor and is a replaceable item. The VW dealers do not sell it, but you can call Europarts in San Diego (http://www.euoroparts-sd.com) and get just the part you need.

Of course, there are other things that would cause it to not start, but from what you describe, I think this would be worth looking into. Do a search of this forum to see other references to the hall sending unit. (Hall refers to a magnetic field.)

Thanks for all the good advise. I have someone coming over with a multi-meter so I can check the coil, and we'll check the sending unit as well.

I miss my van, and want it running so badly, I really appreciate the advise.

My husband just got out of the shower, he says he replaced the distributor cap and rotor, and there is nothing else there. Where else could the hall unit be?

The Hall Sensor is under the Rotor in the Distributor. It is
covered by a plastic dust cap/shield, that can be removed
once the rotor has been pulled off of the shaft.

The 3 wire harness plug at the side/top of the distributor
is the plug for the Hall Sensor. See attached image of a Non
VW Hall Sensor Distributor... VW hall sensor will look similar.

If the engine is getting consistent spark... then the Hall Sensor
"should" be OK, but it's worth a shot if everything else has
been checked.

As Windy Gregory mentioned, the distributor will need to be
disassembled... my earlier post made it sound like you just
have to remove the plastic shield... not so.

Remove the distributor from engine and take apart.

Attached image (this time) of a VW (but non Eurovan) distributor.

Its got spark. How does the spark look? Nice and Blue? If so, I cant understand how it can be the Hall sender.
What kind of engine does the car have?

I am lost.... I have never heard of the 5 cylinder 3.5 litre.
Mine has the VR6 but has no distributer as in the normal ignition systems. Mine seems to be built into the coil unit and very expensive. I needed a new coil and it costs 700 dollars. I finally found a Beru without the quality VW box for half the price.
Strange that a few years ago the auto maker proudly put a quality stamp like 'Made in Germany' or Made in the USA'. Today i do miss the 'Made in India' stamp on the VW. After all the engine blocks, cylinder heads, pistons, crankshafts, camshaft, axles, and all forged parts on the car is made by Bharat Forge in India. The Lemförder suspension and steering parts too are made there.

If you have fuel and spark, it's your timing..

I assume that the engine cranks, of course, that the spark plug wires have not been moved since engine was last working, that you already have tried to start engine with starting fluid, and that you have checked that you have sparks.

Check compressions first (by ear and better with gauge).
Check timing belt. It might have slipped without breaking the belt. Crank engine while somebody else check if belt is actually turning the camshaft. Then check that belt has not slipped (crankshaft and camshaft pulleys at TDC).
Use timing light to check ignition timing.

Let us know...

Just wondered if your HT leads are fitted correctly and leading to the correct plugs... you did change your distributor cap?
If so you must hear some explosions from the combustion chamber. Dont use starter fluid just in case your manifold is of plastic. You might be looking for a new one if this happens.

Okay finally got a multi-meter to test the electrical.

The wire and the coil have zero output.

The positive and negative wires going to the coil from the battery are both fine, but there is a third wire and we don't know what it is for, anyone?

I'm looking for a wiring diagram of all the wires for the left front corner and what each wire is for.

Thanks to anyone who can help.
