2001 Hyundai Accent loses power or stalls




By miskellk on Apr 05, 2009

" "
My Mom's 2001 Hyndai Accent with almost 40,000 miles started losing power and quietly dying while making a turn or on the road after attempting acceleration. Then it starts up again OK and runs. We have taken the car to two different well-recommended mechanics, and they have had diagnostics run. The problem doesn't always happen, so it's hard to diagnose, and when she gets the car back everyone thinks it is fixed, and it does the same thing after she drives it for a couple of days. The car has had sensors changed, computer changed (replaced with used one), transmission changed (with used one), more sensors changed, new fuel pump. And this morning when she was driving, the car did the exact same thing, quietly stalled in traffic, but then it starts up OK and runs. Also there is a problem with not being able to pump gas but a trickle before the gas pump shuts off. I always pump the gas for my Mom as she has a hard time removing the gas cap. Before this stalling problem started, the gas pumping problem went from bad to worse, where I had to pull the pump handle partially out to allow air in and allowing in just a trickle of gas, so the gas would not cut off. Is there any possibility that the problems could be related, that there could be a problem with the gas flowing to the engine if the fuel breather tube is completely blocked. And when you turn the engine off, sometimes it there is a quiet tic-tic-tic-tic sound, which sounds like it is coming down the exhaust pipe.

- daves944,

Thanks for your reply. Car is going back to shop tomorrow. I'll post when/if problem is solved, and what it was. Actually the car went to Hyundai for diagnostics. That's when the problem with transmission turned up. And my Mom's not mad at the mechanic, just disgusted with the car. She is 83, doesn't drive much, but doesn't like to be without her car.

Clarification Request

I had one of these in my shop with very similar symptoms. I'm pretty good with this kind of problem but this one had me tearing my hair out and my customer mad. I'd say take it to Hyundai. (HelpingYouUnderstandNeverbuyaDAmnImport)

There is a sensor (dont exactly remember witch 1) That is related with the ECM Motor That Gets The car Just Few Little rpms more wen you turn to encounter the HP needed for the powersteering pomp to be able to assist you turning.. i think its the Knock Sensor Not Sure You should look that up seriously cuz ive seen that kind of problem before, it was the sensor in default reading BUT you SHOULD be able to see the problem with OBD2 diagnostic, if not ask your mecanic to test the resistance of the sensor following the specs of the manufacturer

good luck
