Yes have you done anything to the wiring?

 

The engine temperature sensor for the ECU is on the Inlet side of the block, near the front . . it's the only one with TWO wires, so check the plug is on properly.

 

And the Fuel Pump ECU is in the rear of the car, and has several wires coming from the main Engine ECU - have you disturbed any of the wiring at all?
