Replaced the injector for cylinder 3, still dead. Assumed bad 'new' injector, so returned and got another, but took injector from #6 and put in #3, then 'new' one in #6 (removing the upper intake isn't the easiest job). Computer throws multiple cylinder misfires, and cylinder 3 is still dead (shadetree inspection of all 6 plugs). Leading up to the swapping of the bad injector, there was a few hours worth of work swapping plugs and wires to different positions to see if any of those were bad, but all were good, and still are.
Now on to the ecm, which can't be found in local junkyards, will have to order a reman unit from local parts store.

Did you by chance have the cap and rotor off then have somene crank the engine over while you watched the distributor to see if any spark was visible that should not be. The distributor on 99-02 manily the 99's are noted for problems. I would look into the distributor before replacing ECM.

Enter villager ecm on ebay motors, you should get about 6 pages of ecm's for all years 93-02.
Does the distributor shaft have any side to side play? Also check for any brownish dust on the optical sensor.
