Question about 1993 Mercury Topaz

2 Answers

I need to replace the fuel pump in the gas tank of my 1993 Mercury Topaz. What is the least expensive way to replace the fuel pump? Is it okay to reroute the fuel line to a new tank in the trunk or

My car would crank on Friday but wouldn't start. I normally don't even have to touch the gas pedal and it will start right up. After removing the valve cover the valves were moving normally with nothing loose. But when the key was on there was no hum from power getting to the fuel pump in the tank.

You must replace one in the tank, please don't try to modify the fuel system. If you never did it before I would let a professional do it.

You can pull the tank off, and put new straps on after. or cut a hole in the trunk just above where your fule pump is and remove the pump that way, patch floor afterwards

So you have power there, why not try a little whap with rubber hammer near it while key on to see if it will do anything. I;d try it just to see if it will come back to life.

SOURCE: How do you remove the fuel pump from the fuel

only two things it can be. one would be that the ground strap is still atached, the other thing is the gasket under the pump has welded the two together. in this case, if your sure you have the retaining ring all the way loose, tap pump with a brass hammer(only!) then work it loose. good luck.

SOURCE: I have a 1993 Mercury Topaz

I have the exact same car and man did we have a hell of a time figuring this one out! I wonder if you have the same cause as I did. My fiance replaced the fuel filter, the fuel pump, the battery, the spark plugs, the ignition switch and still the car would randomly leave me stranded or simply not start. Turns out that there is a wire that goes to the back of the car to the fuel pump. Signs of this being the problem were when the car would die the hazards would not be on or would be dim and get dimmer. Slamming the truck helped and they would get bright again and at that time I could start the car and get home. Another sign was the gas gauge, even though it worked wasn't always accurate.

Another thing it could be, since you were vague, is another issue I am currently having, is that the key isn't turning so I figure now I have to either replace the ignition or something to do with the gear shifter and pins in the steering column.

Anyway I am learning that this car, even though lasts a long time, has a lot of problems when it is 15+ years old.

Your answer is to get a test light with a lead on 1 end and test the feed wire under the back seat ,,turn on the ign switch and put test light in wire and other end to earth ...if light lights go to tank and test again then play with wires to see it they will go out if yes then replace wires from around the firewall to rear pump wire connection and you should hear the pump going..

My car ran out of gas, and now that i put more gas in it ... it still will not start..

1st off this car is fuel injected, there is no carburetor. How much gas did you put in the tank? At least 3 gallons is required many times to get the tiny electric fuel pump to not **** air. If adding more gas doesn't get it started you may have burned out the electric fuel pump, the reason is this, the electric fuel pump that is inside the fuel tank depends on the gas it sits and runs in for cooling and lubrication, so when you run out of gas it can and may times does destroy the fuel pump many times, this is even more so true on cars with lots of miles on the pump. You can try adding more fuel and taking a rubber hammer and hitting the bottom of the tank while someone turns the engine over, this may free up the pump, if not then the pump must be replaced, this requires the fuel tank to be removed from the car to gain access to the fuel pump.
