I had the exact same problem with my van.  The = Engine would occasionally shut down out of the blue and when trying to = restart the relays click like crazy.  It turned out that the cable = for the ECU and Fuel Injection power supply was bad.

I would also check the ignition switch first as Mark = suggested.  Easy to do.  I you have a Digifant ECU that has = been converted for the Digitool you can plug this in and see what the = Digitool says.  What I saw with my problem was simply no power, = dead (if the ECU doesn't get any power, the Digitool doesn't get any = either).  Test the power supply to the ECU by removing the right = (passenger side) connector from the relay box in the engine = compartment.  The connector has two pins.  The left one = (driver side) is the power supply (solid red) and the other one = (red/black) is for the dealer diagnostic tool (so you don't need to = worry about connecting it for the test).  Connect a cable to the = left pin and connect it straight to the alternator.  If everything = is fine now you also got a bad cable.

Good luck!

Subject: Van Dies, Relays clicking...

Have an '86 Vanagon in the shop right now.  = Customer has been complaining of
the van dying occasionally (sometimes after going = over bumps).  When he tries
to restart the engine turns over but won't = start.  He hears relays clicking
several times(like the two in the engine = compartment) while he is turning it
over.  Then cranks it again with no relays = clicking and the engine starts.
I am leaning toward a bad ignition switch on this = one.  Anyone ever had a
similar experience.  Engine runs pretty well = otherwise and has lots of new
parts on it (the guy was basically replacing = everything before he brought it
to me, trying to solve the problem that way).
Any insights would be appreciated.

Thanks,
