So I have the vehicle listed above with a v6 engine. That will not run on 6, 4 and 6 cylinders are not working at all. Injectors done, coil packs done, fuel pressure done, compression is fine, swapped coil packs around.

I have even run the motor with the coil packs with a plug in them earthed to the body and they are sparking fine.

With the inlet plenum off you can see the injectors firing.

I am lost.

Hello my name is Dave.

Sorry to be there bearer of bad news, but these ECU's are notorious for burning coil drivers. I have 2 05 Tributes which are identical to the Escape except for body panels. I have had to replace the ECU in both of mine for this issue. If you could get the exact codes it would be greatly helpful in a proper diagnosis. If you have to replace the ECU and decide to try a used one keep in mind you need to be able to get the key with it or you will have to spend a considerable amount of money to have one programmed to the ECU.

So lets start with the codes, here is a link to our tutorial on retrieving your codes:
