1991 Mercury Topaz Problems
Fuel pump failure can cause the engine to crank but fail to start. Diagnosis will show insufficient, or no fuel pressure, and fuel pump in the fuel tank will need to be replaced.
The vehicle may lose vehicle speed signal, which can affect speedometer operation and transmission shift quality. Most often the Vehicle Speed Sensor is faulty, however, at times, the driven gear inside the transmission is at fault. Replace the Vehicle Speed sensor and inspect the driven gear upon sensor removal.
Poor rubber material used in the motor mounts can cause them to fail, leading to a knocking noise or lifting sensation on acceleration. The motor mounts will need to be replaced with revised parts.

My water pump went out. It is pouring out antifreeze. I found the pump at carquest- the only place that had it. Now the mechanic says I need a hose- and the ones at the local stores have one that is too small. This is a hose I cannot put my hands on, I don't know the name or where to find it....
The low and high end ports on the AC system are the old design and are now illegal to use i tried to hook up the new ports that are sold at autozone but they dont fit the threads because its about a bicycle size thread and are too skinny to fit inside the new ports so how can i fill up this system?
