[Diy_efi] Grounding issues with Honda ECU

[Eck, Joel (Houston)]

I agree. Honda ECU's have strange problems come up when one of the below =
happens. Another lister just replied about redoing some of the existing =
grounds, probably not a bad idea either, although I might investigate =
the below first to avoid buying new cables if not necessary.

Unfortunately, you'll have to poke around on the engine to find the =
grounding location(s), unless someone else cares to share that info...

Likely problems are corrosion in the engine block ground.
No engine block to chassis ground (voltage potential possible)
Loose ECU ground
Loose ground wires
Corrosion at point of connection
Intermittant/Flaky wire
