Mercury Tracer Repair Question
Fuel pump works, but does not pump fuel!
A little history...
The car was bought used 6 months ago with a known problem with the cooling fan. The relay was found defective, replaced, and the cooling fan worked!
However, later, the fuel pump quit working...so it was removed, yet it was determined beyond all doubt that the unit was functioning. The fuel filter was replaced, and wiggling the fuel rail caused fuel somehow to start flowing again momentarily. Why, oh, why is the car telling the fuel pump not to work? THere is juice at the pump, but when it's supposed to pump fuel, it doesn't. There is a safety switch at the rear, but it remains open.
Now as far as the cooling fan goes, the relay keeps frying at the base where it connects to the box. Could we have a related electrical issue or just bad luck?
What happens to the power to the pump when the fan relay blows?
With the relay in car, you should hear it click to energize!

The tracer has a "ccrm", or constant control relay module located underneath the air filter housing. It is basically a unit with three relays in one. It controls the engine cooling fan, the ac compressor and the fuel pump. It is possible for one "leg" of the unit to go out and the other two to work OK. I had that problem with my 99 tracer cause my ac compressor wouldn't run, but the other two things worked OK. I replaced it for $38 at a junkyard, now everything is AOK. That could be your problem. :-)
