No Ecu Communication

[RonaldFord]

Hi. I bought a 1999 Mondeo MK2. 2.0L Zetech engine. Unbeknown to me, this vehicle could not be repaired by the Ford Dealers. Dash lights up when you turn the key, but the engine does not crank. Starter is ok. The Dealers replaced the ECU and interior fuse box. They swopped these items from an identical vehicle without any luck. The "faulty" ECU and fusebox worked fine in the other vehicle. The only items they did not swop was the engine compartment fuse box and the wiring looms. They checked the engine and dash wiring looms and found no problems there. They could not communicate with the ECU. Please advise what could be the problem. I checked the connectors and engine fuse box. They all seem ok. Thanks.
