so i have this problem, and have had this problem for a while, where when i have a quarter tank of gas or less and make a left turn going faster than 10-20 mph, the engine dies. Then after less than a second, it comes back, full throttle.



it also does this when i accelerate real fast and am low on gas (not empty, or close to empty, just low). it has also done it when i have a full tank, which seems to throw out the theory that the gas sloshes around so much that it runs out of fuel.



Any ideas? My theory: something wrong with the fuel pump, but what do i know. Most likely, it will be some gremlin in the wiring that i will spend months looking for and never find.

pull the pump out of the tank and have a look, its not hard to do

Yeah check the Filter screen on the pick up of the pump. Mine did the same thing and the screen was really dirty. I cleaned it and it worked fine after that.

cool, thanks for the tips, i'll have to try this out

Could it possibly be a clogged fuel filter? (my friend with a mustang 5.0 suggested that, but he drives a ford, so what does he know? lol)

Yeah I guess it could be that. But I would check out the screen on the pump pick up first, because I replaced my fuel filter thinking that it could be the problem but it wasn't.



If you need any help with how to get to the fuel pump let me know.

your fuel gauge may not be accurate...

fuel level maybe lower than indicated....

my engine cut off recenlty during a very hard left...but then turned right on again. I remember this happened to my friend in virginia...and he bought a new foam filter from mazda that sits at the bottom of the fuel pump.



I did the same this week and stopped by the dealer to order one. It was $10. should solver your problems https://www.nopistons.com/forums/pub...IR#>/smile.png

he knows that if you dont change the fuel filter every 40k miles that the top speed drops to 30mph

that's what i thought, but when i went to fill her up, the tank only holds like 12.5-13.5 gallons

the most ive ever put into mine is like 11.5-12, i think maybe its just running out of gas

RX7Aggie 04-22-2003 03:41 PM

no, it does the same thing after i have filled up, and even after 20 miles or so off a full tank

By chance, do you have a fuel pump kill switch installed? My 87 t2 has had the same problem. After I installed my switch, the ground started to come loose. Everytime I made a hard turn at low speeds, it would die then would start back after the car would come out of the turn. I cleaned the ground and it was okay again.

RX7Aggie 05-07-2003 12:53 AM

actually, yeah i do have a kill switch installed, so this might be it. i changed my fuel filter yesterday and cleaned the fuel pump basket with alcohol. the fuel filter was sooo undersized, at least compared to my new one from advance auto (about 1 1/2 " shorter, 1" smaller in diamter), and wasn't even mounted, just dangling. so i changed it and attached it with zip-ties as best as possible.



it idles much better, and i'm going to start it up tomorrow and see if it hesitates like before. i'll push it in a u-turn and see what happens. It its bad, i might have to check the switch theory. either way, the car seems to run a lot better at low rpm's with this new filter.
