I need an electrical schematic for my LA105

I can do my own troubleshooting if I have a decent schematic. An explanation of the fuel pump vacuum system operation would be helpful also

The vacuum operated fuel uses the crankcase pressure and vacuum pulses created by the movement of the piston. Any air leak via a bad gasket or seal can cause problems.Also blown head gasket cause oil to discharge through the fuel pump vent system.

Sounds like you would benefit from buying your own tech manual. This CD will give you all the diagnostics, tech specs, schematics etc. that you will need for any repairs. I got one for my machine LA 145. It is excellent.

Kia 03 Spectra fuel OBD code P0230 primary circuit failure. Relay does not pick up Fuse is good. No spark on the ignition - relay does not pick up fuse is good. What is in the primary circuit and where...


Unfortunately there are no mechanical fixes available because that trouble code indicates a malfunction somewhere in the electrical circuit for the fuel pump and that would include wiring from the battery to the pump, the fuel pump control module and the and the car's brain, the ECM. It can be a loose connection, but if one is not easily found, then the problem has to be tested with special electrical testing equipment. More information is available but I can't post an illustration of the troubleshooting for this Diagnostic Trouble Code.

There is, however, an illustration that describes that troubleshooting at this location currently:
