1990 Mercury Topaz ProblemsEngine Cranks, but will Not Start - No Fuel Pressure
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.
1990 Mercury Topaz QuestionsActually, it's an 88 Merc Tracer. It will turn over but no spark.. (1 answer)
We have an 88 Merc Tracer my son just bought. It was running rough so we replaced the plugs n wires. Everything is gapped correctly, firing order is correct. We can't get it to start. It cranks over n you can smell fuel, so no fuel issues...its just not sparking. Any ideas?
i have a 89 mercury tracer station wagon and my rpm gage quit working
My car is actually a 1989 but wasn't given the option to select that. I need to replace front and rear motor mounts. Is it possible to do this myself without going crazy or tearing up the car? Have been looking online for instructions of any kind but haven't been able to find anything.
