Have just carried out a conversion to a 1990 4 pot 1600cc to a 6 pot 2000cc. Have the engine, g,box, 2000cc harness and ecu. The fault is has no spark, fuel pump, or injectors pulsing. Its like the ecu isnt getting correct power ignition feeds so can power thoses electrical items, but ecu has many power supplies. Does anyone have a wiring diamgram so can check has correct supplies? Also about 6inch away from the ecu connector on the 2000cc wiring harness it has x1 black 3 pin plug and x1 white 3 pin plug, do these do anything? Is the front engine bay fuse box the same for both cars? Thanks for any help, all be appreciated!!!
