"I have never heard of a water pump binding so bad that it bogged an engine down" It sounds like parts and labor are now being thrown at the car, without an accurate diagnosis of what works and what doesn't work. It all began with a dual action fuel pump, in an attempt to correct a vacuum leak, which turned out to be OK. Without reading through all this thread again, I am wondering if a dry and wet compression test was performed, to verify compression numbers, as a base point of knowledge. I know I would not be pleased as this bill climbs higher and higher, with no positive results. Good diagnostics is always the key to a successful repair.
