Hilux computer problems

Postby yendor » Mon Jul 03, 2017 4:10 am

I have converted a 2003 Toyota Hilux 3l turbo diesel and done 3000km but having problems with the EMS computer bringing the engine fault on the dash and going into limp mode. The injector pump has four electric connections/sensors that are not happy with WVO but will run happily on diesel. The computer is an older type that does not keep a log of past faults and resets every time you switch the key off?
The other problem is the return line on the injector pump is individually connected to return to their respective tanks but will cross contaminate WVO into the diesel tank which blocks the fuel filter. Can you just loop the return line back into the inlet side without damaging the pump?
Hope someone can help thanks.

Yes I and many others run on WVO with a looped return. Its not looped on diesel, so that any air that gets in the loop gets cleared out once in a while.
