Engine shuts off while driving?

Lets scan for codes and then return here and let me know what the codes are. I will be able to further help with those codes. The check engine light may not be on at this time but those codes will still be stored into the vehicles computer.

These guides will help us get started to help find the problem

Please run down these guides and report back.

Hyundai Accent Viva stalls in very hot weather. Starts again after 1 hour cooling down. Runs for 20 minutes and stalls again.

First thing you need to do is have it scanned for codes.Post the exact code numbers not code descriptions. This guide will help

Please run down this guide and report back.

If keeping the gas pedal slightly depressed works and you do not have any troble codes, the idle control system is not working correctly. Have the throttle body and IAC cleaned. This would usually cure excessive low idling which would result in stalling.

They say it takes an hour before it will restart so doesnt sound like a iac.It would atleast restart sounds like something is getting hot failing and causing it to die while driving.

Maybe the ECT.

I was thinking more likely a crank shaft position sensor or something along those lines.

IT sounds like a cylinder misfire. You need to have the computer scanned to identify where the problem is coming from. Most parts stores will scan it for free and tell you the trouble code. From that, you will know what part is the issue.

Let me know if you have questions.

Car starts and runs for about ten miles then it just shuts off. let sit awhile, few hours, then starts again. Will not start with ether when this happens. Checked for spark after shut off, and am not seeing any. Coil saturation? or ignition mod? or what? Coolant is good, no leaks. Vapor lock. gas cap is good.

I have seen crank shaft position sensors do this on Hyundai's they over heat and shut down. i proved this once with a bucket of water poured over the sensor when it shut down and the engine started up straight away again. probably not worth going to that extreme. i would be scanning and seeing if there is a CKP code set.

my car starts fine. I will be driving and it shuts down, usually within 5 miles of driving. the car will crank but not turn over. if I wait 30 minutes it will start again and then the car will shut down again like described above.. what's the problem?

Hello,

it sounds like the crank sensor is getting hot and failing on you. When the car shuts off and you try starting it again does the tachometer move at all? Has the check engine light come on at all?

My vehicle listed above GL will shut off on me when driving. We have replaced the fuel pump and fuel filter and gas cap. We need help for the next step.

Hi and thanks for using 2CarPros.com.

I do have a couple questions. First, does the check engine light come on and if it has, have you checked for trouble codes?

Often times, a bad crankshaft position sensor will do this. The car will start and run until the sensor gets hot enough and then lose connection and shut the engine down. Take a look through this link. It describes what can happen. Let me know if it sounds like what you are experiencing.

I will watch for your reply.

Car stalls when turning corners also shifting when driving takes an extra few seconds to kick in

Hi there,

how is the base idle speed? does it feel surgey and rough in drive while stopped at lights? if so get the tune checked, including all filters and have the base idle and the idle control motor checked, run a scan to check for any unresolved fault codes, start here.

2000 accent when i go down the road it drives ok but if i reach seppds of 55 to 65 it stops all of a suddens and will not start then after about 2 hours it will start up and run again someone says that it may be a fuel switch or something like that is there a switch like that or what could it be PLEASE HELP

No fuel cut out switchs that will make the car stall at 50mph. Is the check engine light on? If so have it scanned for codes, this will help pinpoint the problem.If no light, when it is dead you will need to test for spark and fuel pressure to see what is missing so we have a general direction to go in

I own a 2000 model hyundai accent, automatic. i have had it for twelve months and it has spent 6 months in and out of the mechanics. its problem is when it has a full tank of fuel it shudders and stalls, it is very chunky to drive and has no pick up when you first excellerate you have to pump the excellarator at least twice to get it to move and when it does move it is very sluggish. has trouble making it up hills. the car runs a bit better on less than half a tank of fuel and i have noticed it goes a bit better when it has been washed or it is raining. i have had a new O2 sensor put on it, a new alternator, new battery, new fuel filter, air filter, fuel pump, full new exhaust system (2inch sports, with extractors)including the catalic convertor, spark plugs. the fuel injectors have been cleaned several times and yet the problem is still yet to be diagnosed. The car has been taken to several mechanics as well as hyundai and is still running like a junker! PLEASE HELP.

Have you tried starting it without the fuel lid cover? The most covers have a non spillage protection and takes in air when there is vaccum in the system. It might be that system that is defective in the cover.

Just a thought, I tried it on a Diesel car several years ago.

The car turns off as soon as it warms up. It doesnt over heat it just turns off as soon as it warms up to where its suppose to. Won't turn back on until the car completely cools down.

Have you tried replacing the ECM. this is the brain box under the dash. It maybe overheating and shutting you down. The Part will cost about $775 from the dealer or you can go to a junk yard and get it about $30 just ask for the ECM and not the brain box. You can use any from 2000-2002 Hyundai accents. if you try this please post if it works.

Hi, I've owned this car for 8 months and the engine light has rarely been off- it regularly judders and stalls when I pull away from stationary. I've had it looked at by a garage and so far have had a new catalytic converter, stepper motor (is this AKA an idle speed actuator?), 2 sets of spark plugs and leads, 2 new lamber sensors and 2 new coil packs- none of which has made any difference! The engine light is still on and the fault codes are 1513 and 1553 which seems to be "idle speed actuator (open) open" and idle speed actuator (close) open". What does this mean and what do I need to do to fix it?! Any advice gartefully received before I take a big stick to the car and beat it!

Don't beat it with a stick. However, I know the feeling.

The number one cause of misfires on this engine is the plug wires themselves. Usually, they track somewhere out the side of the plastic insulator that goes inside the plug tube.

With the engine off, pull each plug wire off the plug and just rest back on the plug without clipping it back in place. Then start the engine and pull each wire off the plug separately and return. When you pull the wire off the plug, you should see spark jump from the end of the wire to the plug terminal. If it leaves the wire anywhere other than the end of the wire, then you'll need new wires. If it arcs at the coil, you'll need a new coil. If it arcs between the coil tower and wire boot, you're probably best off replacing the coil and wires.

Also, you may want to check for vacuum leaks. The PCV has a history of leaking causing a lean mixture and setting this code. If everything I mentioned looks good, chances are the idle air actuator is bad.

Let me know if you have other questions, and thanks for using 2carpros.com.

PS: Make sure the plug wires go back to the same plug, Don't mix them up.
