Fuel issue I've got a 2000 Mazda 626 4 cyl, the will not run. It's not getting fuel. I tested the relays and that's not the problem. The fuel pump doesn't come on. I got it to start with starter fluid but it quickly dies. I have a feeling the pump is shot and will need to be replaced. How do I test to see if the pump is the actual problem. I'd really hate to do all the work to replace it and have it not be the problem. Also, where is the fuel filter located? Thanks in advance!

Sixteen year old car with only 40K miles must not be driven often, or sat for some time. I would suspect fuel system issue, such as bad pump, clogged filter, bad regulator or faulty injectors. Start by testing fuel pressure.

You Mazda does not have an inertia switch like the fords do. The only things that control the fuel pump are the pcm, fuel pump relay, and the fuel pump fuse.

try the fuse or reset button in the trunk..drivers side black and yellow tag on it..

check relays/fuses first then the pump if you know how to test it
the pump is easy to test locate any fuel line unplug it tell a friend to make a quick one key turn if squirts fuel then pump is fine
but check the pump relay first to make sure and to begin with simplest
it seems you can tell it is the pump but you don`t know where to start

Check the fuse for the fuel pump. if its bad replace it if it blows again change the fuel pump its on its way out

5 Inspect Fuel Pump Low Fuel Pressure.
6 Inspect Engine Control Computer Incorrect Operating Information Being Delivered and Sent From The EEC.
7 Inspect Fuel Pump Strainer Clogged or Dirty Fuel Pump Strainerat.
8 Inspect Fuel Rail - leaky Fuel Rail

From April 2010? What did the problem turn out to be?

yes it isn't that much if you buy them.they slide inside the coupler and release the line.

Answer to question Where is the Fuel Pump relay on a 1999 Mazda 626.

The relay in in the cover box that contain a variety of fuses just behind the batterty on the driver side of the car. One has to press the tab and remove the cover to see the relay. The cover give a brief description of the fuse and relay locations, but does not call it fule pump relay. The blue arrow point to the fuel pump relay

See about getting a fuel pressure test. Or if your bold just go ahead and change the fuel filter. If both fail you might need a fuel pump

Hello, I am going to make a few assumptions here. The vehicle has an electric fuel pump and you replaced it. The vehicle has fuel injection. The engine is actually cranking, just not starting, when you say "car still won't crank". You are getting fire to the spark plugs at the plug ends. You checked the fuel pump for power at the pump. No power, then you back traced the wire to the fuse block and checked the fuse to see if it was blown. If the fuse is good back trace the power to the ignition switch and/or ECM for power. You have power at the pump, check the ground and make sure it is connected properly. Will the pump run when someone turns the key on? Pump runs, check fuel manifold for pressure. No pressure, check the fuel filter for blockage, or replace it. Fuel pump doesn't run, new replacement pump is defective. There is usually some type of control module for the fuel pump on fuel injected vehicles. Good Luck, RAC
