Hello, my name is Mark and I will try help you with this.
I see you have changed various parts but what testing have you actually done.
Do you hear the fuel pump running?
Is there fuel pressure?
Does it have a spark?
Changing the ecu will not help as the ecu is coded to the vehicle.
sorry couldn't get this box up so whats next to try
Why the poor service rating?
Do you still require help with this?
