Does anyone know of a troubleshooting tree for electrical problems with an EFI Walker? Replaced the ECU about 3 yrs ago. Recently while mowing, it started to backfire and eventually died. Noticed that the fuel pump was not functioning and not getting an idiot light when turning on the key. Fiddled with the harness out of the ECU and the light came on, continued mowing for 2 hours and put her up. Now I tried to start it and no idiot (check engine) light and no fuel pump running. Replaced ign/fuel relay, but nothing. Any ideas? More fiddling didn't help and cleaned ECU connection with electronic cleaner.
