The ECU was an after market TT, There was no error code reading as the led had been disconnected. Looks like the ECU has been modifyed for larger injectors aswell , as it ran extreamly rich.

 

We started at the begining, spark plugs, coil packs , compression test, ignitor, ecu, wireloom from there getting the error code to work , once it worked , we got rid of each error code one at a time.

Sounds like a great bit of fault finding has been done there:). Wish I was as upto speed with the supras running gear. Very satisfying fixing things like that.

 

must admit - it wasnt an easy one to diagnose we had x2 supras in the unit and swapped everything just about (which normally raises the fault but on this occassion we still could not fix it).

 

so michels boys had a tricky job to do..
