Mr2 Turbo Will Not Start

[gtir350]

I have just fitted a standard ECU after removing the Mines unit to return the back to standard

Now the car will not start,

So far

No spart from the plugs

Petrol getting in ok

ECU error code reports 1247

The Ecu is from a 93 denso part number 89661-17380

Does anyone know what the problem could be ?

Thanks
