I know that the wisdom of the list = says that ECUs seldom fail, but in lieu of a better explanation, this is what I = seem to have. I wont recap the long problem I have had except to summarize:

1982 Vanagon GL Westy air-cooled, = non-California (no O2 sensor)

replaced the t2 sensor = twice

replaced the wiring harness (thanks = Kyle, mine was ready to go)

all FI components check out per = haynes manual (voltages, resistance, etc)

grounds all are cleaned and well = connected (engine, batt and tranny)

After I replaced the wiring harness tonight, I = started it up fine. Reached down and tapped the connector to the ECU and it = died. Started back up and it started that some old running rich and smoky and = would only run with the gas pedal 1/2 way down, and then really badly. = It appears I have checked all components that I can. No sticking cold = start valve, no bad thermo-time switch, AFM checks good, etc.

Only thing I can come to is that the ECU is = bad. Some kind of component that is:

1. sensitive to vibration, and

2. sensitive to heat, and

3. is directly related to the engine = enrichment/fuel control

I guess my question is two part:

1. Is there any way to troubleshoot the ECU = other than taking it to the dealer (40 miles away), and

2. Does anyone know where I can get a good ECU for = less than the 5-600 dollars I have seen them quoted in RMMW and = elsewhere?

Thanks,
