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!!!

I'm afraid you may have missed a few electrical components...

Did you bring the loom with the relevent fusebox and relays (AND ECU) etc?

The loom was still attached to engine with the ecu. they said the fuse box is the same?

      105C thermostat replacement

      You are absolutely right. The strange thing is that when I put the chassis number on the realoem it shows that the temp sensor is not applicable on my vehicle. I will physically check for a sensor. In the meantime, do you think that the removal of the MAP activated thermostat will effect the temp gauge on the dial instrument item 6? I am tempted to add a dummy resistor , 11.5ohms - 13watts , to simulate the MAP thermostat. Your thoughts?

      SLIPPING CLUTCH

      Morning Andrew I normally disconnect the Neg lead only, some folks disconnect both a few even say disconnect both and touch them together. Goes without saying both sensor plugs need to be checked and a squirt of contact cleaner applied never hurts 😅 Dave

      SLIPPING CLUTCH

      Hi Dave, I fitted one of the sensors on the rear but it has made no effect as the light is still there, I will fit the other sensor tomorrow and see how it goes then. You mention the disconnect the battery, is there any pattern to this ? is it both leads or just the negative lead? cheers Paneuro.

      105C thermostat replacement

      Not sure what engine your running but there should be a Temp sensor in the Hose from the Rad to the water pump then there should be a Temp sensor in the housing for the Thermostat Both are shown in realoem for the 3.5 V8 I thought the V8 was the only one with dual use sensor on the Thermostat housing but stand to be corrected Dave
