car starts, runs for 5 seconds and dies.. need help.
ok so i am driving around enjoying my car not hesitating over 3800 rpms.. ahhh... so i notice that my gas is getting real low (right on the E) so i pull off to get some gas. i fill up at citgo with 93 and walk over to the autozone (right next door) and buy some tcw3(or whatever its called) two stroke premix. i start the car up before the premix to make sure everything is cool.. the car starts and idles for about 2 or 3 seconds, then fuel cuts off and the car dies. i can immediately start it back up and the same thing happens... someone help...

but it doesn't idle perfectly, now does it? 
Hey, you asked for advice, you don't want to listen to advice, then fix the problem and tell us how to fix it.
Can you get any RPM by holding teh throttle?

2. What? I forgot to add that the car idles fine before fuel cuts out. Did you add anything to this thread before i started "not listening to advice" ? And who says I'm not listening to anyone's advice anyways?
3. Yeah, I can get the engine to any RPM i want for 3 seconds. Hell, I could redline it for three seconds if i wanted to.

Idleing for 3 seconds isn't a perfect idle. It's not even an idle. Jeez.
Right off hand it sounds to me that the AFM isn't signalling that the engine is running, and not actuating the fuel pump.
Have you tried jumping the yellow wire on the passenger side? That forces the fuel pump to run no matter what the AFM tells it.

Wow, so I guess I added something to the thread, huh?
Think about that next time.
Yellow connector, passenger side of the engine bay, near the strut tower. Jumper it, put power to the car, and listen at the back for the fuel pump to run. If the pump runs, leave it for a minute, then try to start the car.
Also, could be clogged fuel filter.

ok guys, i went to start the car up today to see if i could fix the problem... not to my suprise, i jumpered that little yellow plug and it did not affect my engine cutting fuel after 3 seconds. unfortunately, i am at school and dont have enough money to buy a fuel filter, (the mazda dealer is closed anyways.) looking for some more ideas...
