I have a 1987 Mazda 323 SE that is my only mode of transportation. it is fuking up on me. Here is the outline:
It seems to drive fine in cooler temps. When it hits warmer times in the afternoon.. it will run for a little then just die like it looses fire or fuel. Give it like 30 seconds to a minute...and it will start for a while. Maybe 1/2 mile down the road...it dies again. I bought a new Ignition coil, new spark plugs and new wires. Checked the Distibutor and Rotor...they look almost new. What the heck is wrong!!!! So frustrated right now.
It is fuel Injected too. Fuel gets past the fuel filter. Any thoughts????

Goto an Autozone (if you have one out there) because they'll do a free check for you. Other best bet, goto www.msprotege.com it's a mazda forum, should be able to tell you your problem quickly.

Autozone and Advance Auto want to sell me 2 different over $200 parts without even looking at it. Screw them. I dont want to spend on something that much without knowing thats the prob.
The Forum...I registered but its not allowing me to post. :banghead:

its your fuel pump... since its electric, once that thing goes, your whole car dies. im possitive its your fuel pump.
change that and your car will be great. trust me.

Well, at one point that it died....I check the fuel filter at once...and there was fuel and pressure (I know cause it squirted me with gas). Now that seems like the Filter and the pump are working. I am going to try to pull the pump this week or weekend to check it and try to hook up a make shift power on light to make sure its getting power. Just in case.
I dont want to nickel and dime this thing. Already spent a few dimes on replacement stuff already.
Ignition Module maybe. Hope Not. Expensive.
I know that this seems really funny, but Mazda's have a problem with "vapor lock." Since you said it happens when it gets warm. Take it out, get it nice and warm and when it dies, jump out and release your fuel cap. If you hear the sound of suction or rushing air then it is vapor locking on you. Put the cap back on and see if it fires. If it fires then you need to start checking lines, filters, return lines, fuel pump, etc. I would just start with the small and simple things first. Hope this helps.

Hmmm...can you expand on this one...or is there something to stop this. I have heard that sound when I put injector cleaner in and got gas today. I think I have a high pressure fuel system....so should it not have that sound? I am going to try to follow the fuel lines and check for weak spots.

yeah fuel will get threw the lines when you check it, its not hot and not dead at the time, and its fuel that has been left in the lines. my sister caviler had the same problem, itd go for a few miles, die, stall...fire back up..stall after 1/4 mile. ..its the electric fuel pump. replace that and your car will run fine. i dont think the vapor lock could effect it that bad, because it has an escape/ vent line..i know many vehicles that have that pressure "PERSHHHH" sound when you open the cap, thats just from the vapors in the filler neck running from the tank from heat.

Thats what I like to see. Experience with the same problem. Still gonna cost me a little for a pump.
That problem sounds just like mine. When the problem starts...might as well expect it to come on alot. I still wonder why when its cooler that it seems to work ok.
Thanks! When I get one and get it in and test drive it...will let you know if its working or not.

Heat is your worst enemy with fuel pumps..well excessive heat. in the heat, your car needs to work harder to keep cool. higher rpms, higher fan speed, higher idle kick up ( a/c ) . which will cause your cars fuel pump to run hotter.which will cuase your electric fuel pump to die, stall, sputter. and if your wondering if you get a new one, will do the same?...no it wont. its that your pump is older and needs replacement.

sounds about right. these "newer" cars are crazy. thats why i go for 1979 and older. shits easy as hell to diagnoise and cheap to fix. those crazy fuel pump and there electric computers are buggers. image yoru car liek a computer. if it get too hot it crashes. wait for it to cool down and you golden until it heats up to hot. probably get a fuel pump cheap off ebay.
let us know how it goes.

I had the same problem with a ford made car.
I bet you 5 bucks if you stop using ethonal in the summer it goes away.
In extreme heat the gas expands just enough to not let the return fuel pump work. It gets clogged. I bet that it is chugging from a stop. If so it because when your car runs at 3000RPM you need more gas then when braking it goes down to 1500RPM and that fuel that was being used cant jsut sit in the line. That is why you need the return fuel pump. Use 87 and you'll be fine.
Of course this depends on you using Ethonal gas in the first place.

Ebay...love the price there...better than AutoZone or Advance.
Fuel Pump (http://cgi.ebay.com/ebaymotors/255-LPH-FUEL-PUMP-Mazda-Protege-MX6-626-323-MX-6-929_W0QQitemZ8003812674QQcategoryZ33555QQssPageNam eZWDVWQQrdZ1QQcmdZViewItem)
Around $80 is not bad for one of these.

Seen this problem before, sounds like the fuel pump is shortin out when it gets warm get a test light and check the hot wire to the pump when it dies if the wire looses power its shortin.

yeah, your just like restating what everyone has said..
The pump probably isn't shorting, it's just dieing. When they're at the end of their life they can't pump the high psi needed to run the engine, they still pump fuel, just not the required amount.

seen the same problem first hand and had people that wouldn't listen. it's ur fuel pump, and $80 on ebay is the shit. lol
most people think that fuel pumps either work or they don't.
sometimes they quit, sometimes they get weak.

I dont think that it is bad. Look at my post on the first page.
It only works if your using gas above 87 Octane, though.

I had a 92 and it was doing it two years ago. I think that I would try the cheapest thing first. That is all Im saying. I would rather try the free things first. Maybe thats just me.

With the gas prices....87 is what I use. The cheaper way is let it die on the downside of a hill. Coastin'.

Ok...finally replaced the fuel pump. Drove it to work with no problems....like the last time (Cooler Temp.). Today at lunch I went poking under the hood ans discovered one Vacume Line that came off...looks like it went from the throttle body to some can and split somewhere else. I didnt see it before because its kinda under some stuff in there. There are 4 lines that are at that throttle body..this was one of them. So, Driving home...did not stall out on me at all. :spin: :spin: :spin: Still dont trust it yet..gonna take time.
I really dont want to know if it was that vacume line cause after the money I spent already, for it to be something that stupid, it would piss me off. :fight:

The vacum line could cause an idle surge issue but usually wont cause a car do just die.
