I've bought and tried two unlocked ECU units for my 6 and the engine turns over but won't fire up? I have a Clifford Alarm fitted from previous owner would that be a problem or am i just been stupid and missing something? Help

Does the fuel pump prime when you turn the ignition to the second click? Is there a spark? A bit more info would help people to help you ;-)

Have you verified the ECU's you've bought are actually unlocked? Testing them on another car would be a good way to make sure.

They also need to be de-immobilised, otherwise the ECU will lock itself as soon as it receives a foreign transponder signal from your car. So may sure the ECU's your buying are unlocked AND de-immobilised.

Yes the fuel pump primes. How do you de-immobilise ECU's? I can't verify that it's unlocked just his word that it is.

You need to ditch the transducer ring tat goes dound the ignition swich, otherwise it reads the key, sees it does'nt match the ECU and locks it.
