On my KOEO test i got code 511. This is an electronic control assembly problem, (eca) prob. Does anyone know what the eca is? Could this be causing my pinging problem.

the 511 code is " Read Only Memory test failed-replace PCM" (Power Control Module)

If this is true, hook up a volt meter to pin1 on the PCM and ground to the chassis. See if you are getting 12V.

If you are, then your PCM may be bad.

If you aren't, the wire is severed somewhere. Trace it all the way back to the wiring harness.
