OK, time for my annual spring ritual of a wbx that won't start.  It's
been sitting since November. Battery is charged, 30 liters of fresh
gas in the tank. Grounds cleaned (block to chassis, both ends and the
cluster beside it ). Pulled a plug lead and grounded a spare spark
plug. There is strong spark. (Should be as there is a new coil, HT
leads, Dist cap etc last summer)  Idle control switch specs out
correctly, Replaced the Air metering unit with a new one. no change.
Can smell fuel in the one removed.  Fuel pump hums for a few seconds
when ign turned on. New ignition switch last fall.

The engine cranks but does not fire. On the first attempt after
cleaning grounds it fired once. That's it. that's all.

Any suggestions??
  pmail please as I am on digest.
  Thanks
  Don
