    Try unplugging the air flow sensor and then starting the car. If it starts, look to make sure the vane is moving freely in the AFS and that it returns to the closed position on its own. If it doesn't, start shopping for a rebuilt or used one.
  • you are talking about the mass air flow sensor.? that 200 to 300 dollor part... i was hoping it was just the O2 sensor.
  • maltbmaltb Posts: 3,572
    Well try unplugging it first and see if the car starts. If that does it, then go rob a bank to pay for it.

    The O2 sensor will do nothing for you.
  • A couple weed ago I noticed my 2000 Protégé (1.6) was cranking progressively slower during startup. (I bought the car used over a year ago and had no idea how old the battery was.)
    The alternator seems okay because once it’s started the car run fine with full headlights, etc.
    This past Sunday, after having sit for two days, there was nothing when I turned the key, not even a click.
    I replaced the battery Sunday night with a new Die-Hard and Monday morning it started fine and cranked hard.
    Now this morning, (Tuesday) the battery is completely dead.
    Anyone have any ideas what could suddenly be draining my batteries?

    Thanks in advance.
  • I have a 2000 mazda protege 1.6 DX. Whenever the fuel level gets to about a quarter of a tank it acts like it is not getting enough gas. Runs fine when it has more gas in the tank. I am thinking it is probably a clogged filter or fuel pump is going out. I was hoping someone could give any advice, and if it is the pump or filter please tell me the best way to replace it. Thanks
  • David,

    I am having the same problem. But recently I have figured out how to find out what's doing it. Something has grounded. To test and see what it is,,,hook a test light to your battery,,,,inside your fuse box(inside the car) remove each fuse,,,the one that keeps the light on the tester is the problem. A wire has grounded. Trace that wire and you've got it. It was my horn wire.Had a tiny worn spot from aging and vibes on a bumpy road. This problem drove me nuts for three months.
  • Where is the fuel filter located on 2003 Mazda Protege? Thank you so much for your help with this.

    he High Pressure and the Low Pressure Fuel Filters are located in the Fuel Tank on the Fuel Pump Unit, to replace either Fuel Filter you must remove the Fuel Pump from the Fuel Tank.


  • Could the fuel filter be a cause for the motor cutting out when accelerating?
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,408
    Yeah but I'd be more inclined to test for a bad fuel pressure regulator, also basic tune up. A fuel filter would have to be pretty clogged up, drastically so.


  • Do you know of any procedures to test/replace the fuel pressure regulator? Where its located?

    Your help is very much appreciated.
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,408
    You need a pressure gauge and proper fittings to break into the fuel injection rail. Then you need to know the specs at cranking and at idle speeds. It's best to have a repair manual to talk you through these procedures, or go to a shop and have the test done.

    It should read 30 - 36 psi with the fuel pressure regulator connected and 39-45 psi with the fuel pressure regulator disconnected.

    This test would tell you if the fuel system is substandard in some way. If it reads okay, you go on to other areas such as ignition or sensors.


  • My 97 mazda protege has just started acting up lately. It was fine for a while and now i have to hold the key to start for more than a second to start.

    I would start by checking the battery and then the alternator. You are likely not on the original battery but might be using the original alternator. If so, the alternator becomes the more likely suspect.

    It might be wise to find a garage you trust and have them check out the car for you. You may find that there are other problem areas (example: spark plugs) and the garage may suggest a schedule for their replacement/repair.
  • Help please, I need step by step instructions in removing the center console. I'm needing to reach the air condition fan switch, in order to fix it. The wiring behind the switch has loosened and will work, then stop and then work again. I want to check that because after messing (turning it off and on)with it starts working. Thanks.

    what year is your car?


  • I have a 2001 Mazda Protege with about 85,900 miles on it.

    Sometimes when I make a sharp turn, doesn't matter if it's a left or right turn, my car stalls out. It doesn't sputter, it's more like someone flipped a switch. I'm able to turn my car right back on and it runs normally.

    What could this be?
  • maltbmaltb Posts: 3,572
    Power steering pump. Does it make any strange noises when this happens?
  • No weird noises, it just feels like the wheels lock up.

    About how much will it take to replace a power steering pump?
  • Yesterday, my car's temp guage was nearing hot or at hot on my commute home. I noticed some antifreeze on the ground, but didn't appear to be leaking from under the engine anywhere. When I popped the hood, the only steam coming out was by the antifreeze coolant box. It was boiling hot and overflowing, dripping out causing steam. I continued on my 40 mile commute home with no issues, just stopping periodically to cool the engine down. I would keep the heat on high to try and drain some of the heat away from the engine, but later no heat would generate, only cold air. No warning lights came on the dash, car seems to run and start fine. What do you think the issue is?
