I believe the pump is in the fuel tank on your car and just pull the tank and replace the pump. The less gas you have in it the easier it is to handle. On some cars you have to drop the exhaust system some.

Your 1989 Mercury Topaz will start but won't stay running What should you check?

If your 1989 Mercury Topaz starts but won't stay running, you should check the fuel system, including the fuel pump, fuel filter, and fuel injectors. Additionally, check the ignition system for issues with the spark plugs, ignition coil, or ignition module. Finally, inspect the air intake system for any blockages or leaks that could be affecting the engine's ability to run smoothly.


Why would a 1994 Mercury Topaz idle low but run fine until you go up a hill when it loses power and also stall in traffic?

A low idle could be due to a faulty idle air control valve or a vacuum leak, causing poor fuel-air mixture at low speeds. Losing power on hills and stalling in traffic could be due to a weak fuel pump or a clogged fuel filter, resulting in insufficient fuel delivery to the engine under load. I recommend checking these components for any issues.
