2005 4.4i head not firing at all after gasket replacement
I had a blown head gasket on the driver side bank of my 2005 4.4i. It was still moving and I drove it to a technician with more than 20yrs BMW experience. It was driving fine except for the morning steam blowing out of the driver's side exhaust outlet. Both heads were taken out and sent to the engineers, they were returned and fitted. The problem now is that the driver's side bank that had a blown gasket won't fire at all. There is absolutely no electrical power going there, so there is no spark or fuel at all. Basically, he tells me the head is just quiet and he needs time to figure out what it is. Unfortunately, the car has been at his workshop for two months now. Can anyone please suggest what needs to be done or checked??
