Differences between Daihatsu YRV and Perouda MyVi engines


I have a 2002 1.3 YRV and have fitted a low-mileage 2012 MyVi engine which is a guaranteed runner. But we can’t get it running! Retained the YRV injector rail, ECU and Immobiliser module / keys etc so the replacement engine is just mechanical, Nothing. Swapped the crank angle rotor - nothing. Tearing my hair out. The engines seem identical apart from an additional oil pressure port on the back of the crankcase. Are these effectively the same engine? Help!!!


I don’t think i’ll be able to help, but those on the forum that can would probably need a bit more info:

  • does it crank?
  • can you hear the fuel pump prime?
  • is it sparking?

From what I know they’re functionally the same, but may operate of different fuel/spark/crank sensors/types.



Hmm I thought it was immobilised and different ecu?
Also know there’s different immobiliser between auto and manual just in case you’ve swapped that?


no, the injector rail, ECU, wiring harness, Immobiliser, keys, crank position rotor and all that gubbins came from my 2002 YRV 1.3. What I have in is an engine that appears mechanically identical to the YRV, which is the 2012 MyVi 1.3 vvt. The only electrical parts that were not present on the YRV are the MyVi pick up which is behind the timing cover ( and could I accept be in a different angular relationship to the rotor, but appears identical ) and what looks like an additional oil pressure port on the back of the MyVi crankcase , which is not connected to anything now. Oh, and I replaced both Lambda exhaust 02 sensors. Help!!!


what i mean is from what i’ve looked at them - its the loom that has some different parts.
same as between sirion versions.
so you need ecu and looms to match the engine
