(I already replied in the thread titled 2002 accent won't start, but I'm starting a new thread in case my situation is different, or anyone else has any suggestions...Thanks!)

Hey All. I have a 2001 Accent, 54K miles (Sig needs updating) and automatic trans. Always runs beautifully.

In January, I was travelling, when I stopped somewhere and turned off the car. When I got back in the car 20 minutes later, it would not crank. I kept trying off and on for the next hour and it finally cranked. Car turned and turned like it was trying to crank, but not getting any spark or fuel.

Instance Number two: February - car would not crank after sitting for a day or so. It finally cranked after ten minutes. Same thing.

Instance Number Three: March - Got home this morning from a trip out of town this weekend and turned off the car. Got back in the car three hours later to head to work, car will not crank. It still will not crank. I have tried everything. It's storming bad so I can't get out to check for spark. But the battery is not even two years old, and the plugs and wires were replaced last month.

This is very frustrating. I am starting to feel that I can't trust the car. Someone suggested the Crank position sensor. How can I tell if this has gone bad and how do I replace it. Any other suggestions? My main problem right now is time wise, I'm very limited in what I can do. I just don't have enough hours to sit and wrestle with it.

I have checked the HMAservice site. Can't find anything about crankshaft position sensor.

I'm lucky that I have an older (and unfortunately...more reliable) car that the wife and I keep as a backup for situations such as this. I'm trying to avoid a tow to the dealer for repair, but I am tired of this car screwing with me.

Thanks!

Stephen

I Know the feeling (IMG:http://i67.photobucket.com/albums/h305/MMMJ/2-1.gif)

Go to the dealers & buy a crank sensor ...... Go home wait for the car to go cold, undo the 10 mm bolt that holds the sensor in ...... Un-plug the sensor ........ pull it out, slide new one in, bolt up ...... Plug in & have a go @ starting :)

Do I know the part # ? ........No ........... Take your Vin # & get the dealer to look it up :)

Thanks!

I have the DOHC engine. Is it roughly in the same place?

No idea .......... Heres a thought ........ Go & have a look :bwekk:

Immobilise system?

You could....... But it wouldn't help :thumbsup:

My dealer wanted a TON of money for the sensor (No surprise!). So I went to Autozone last night and rented an Actron Diagnostic Scanner from their Free Loan-A-Tool program. I first checked for spark. Got no spark from any of the plugs. Then I scanned the OBDII codes. I got a P0335 No Signal From Crankshaft Position Sensor. Yup, it's dead.

I can only guess that what happened the two previous times is that the sensor was flaking out and causing the car intermittently to not start.

Finally, it died for good. The car hasn't cranked since Monday.

I ordered a new one for $54.00 from Autozone and should have it by Friday. So this weekend, I can will be zipping around once more. I'm NOT looking forward to trying to get the sensor out, I hear it's a booger to get to.

Status: online OK: Update, I got the new sensor installed (wasn't hard at all, lucky I have small hands!) and the car still refuses to start!

Turns and turns and now I'm smelling fuel too, where I wasn't before.

Battery and alternator tested, both are good.

Code went away after replacing sensor. Car doesn't display any codes now. It's almost like something in the ignition is disabled?

any suggestions? I am trying hard not to have it towed, but I'm running out of time.

are the coil packs operating ?

Or at lease getting the signal to fire :innocent:

how do I test those?

This is the bit where you need wiring diagrams to ascertain which wire does what on the plug that goes to the coil pack..... Getting things wrong here could damage your Ecu, I havent needed to get that up close with my hyundai so I can't tell you.

I guess you will have to pull the diagram from the Hyundai site & have a look

what was the part number of the crank position sensor you got (Not important I'm just interested) :thumbsup:

OK, this is really weird. I didn't have much time this weekend, other than to change the CKP sensor on Friday afternoon. We all know that the car didn't start. Saturday, the car didn't start either. Sunday, nope. Monday, I gave up. I called a tow truck to tow it to the Hyundai dealer. I go outside and put the key in the ignition for the tow man, and tried once more. Fired right up. At first, it was hesitant to fire but did crank. I turned it off and tried it again. Fired up again, but shook a little then smoothed out. Ran some errands around town and now it's firing up smoothly every time.

I still don't trust this car. It has a mind of its own. I won't be going off on long distances until I know for sure that it's running right.

The thing is...once I replaced the CKP sensor, the error code went away on its own immediately, without me having to clear it. Subsequent readings from the OBDII scanner showed "NO CODES FOUND - PASSED".

But it still would not crank. So I'm going to drive it a week or so and see what happens. :whistling:

At least now it's running. :clap: Decided to run AFTER I'd already called a tow and made arrangements for the dealer to diagnose the problem.

At least now I can use my gas. Right before it quit, I'd filled the tank completely up and only gone a mile when it died at my house. And with gas prices, I had to drive my other car which has an even larger tank :w00t:

Think you may have gotten some bad gasoline? With the major change in temps we've been having lately, condensation could be a problem. You also mention that you have new plugs and wires, did you do the wire/plug change? Just questioning to make sure the correct plug is to the correct wire (I had a dealership completely show their ignorance with just this).

Just tossing you some ideas.

OK, the saga continues. I got the car back from the dealer on the 14th. He replaced the positive battery cable and claimed that it was corroded internally, causing the crank sensor to not get enough voltage to start the car. Makes sense to me. Sunday, the 16th, the wife and I drove it down to New Orleans to the port to set sail on a 7 day Carribean cruise (A belated honeymoon - we were married in December). Car didn't want to start at first Sunday, but we were in a hurry to leave, so I took it anyway since the baggage was loaded in the car. Car ran fabulous. Got a personal best of 35.5 MPG highway with the AC on part of the way down to New Orleans. This was cruising at 68-70 MPH babying the right foot and not being hard in my driving.

Sunday, the 23rd, we arrived back in New Orleans, car had been sitting for a week. Didn't want to crank. I tried for a minute and it finally fired. It was semi-cold (in the 60's when we got off the ship in NOLA). Car ran great, and fired up as long as it was hot.

This morning: It's about 40 degrees out. It's only the second day I've tried to drive the car since I got it back. CAR WILL NOT CRANK!!!!!!!!!!!!!!!!!!!!!! It turns and turns and turns but will not fire. I'm SO ****. I called the dealer and told him as soon as I get it cranked when it warms up I'm bringing it back to him and he can have it until it is cranking the first time every time.

I want to keep this car, I really do.

But I've never had a car that gave me such fits before. Ever. Even my 18 year old Chrysler that I drive as a backup when this one quits on me cranks the first time, every time and has never left me stranded - take that HYUNDAI!

I love this car, it gets terrific MPG and it has relatively low miles for it's age but I need something trustworthy.

In the past month, it has:

New Positive Battery cable and terminal

Crankshaft Position Sensor


Plugs

Wires

K&N Air Filter (It was doing this before I installed the air filter)

Well sure enough....as I thought...once it warmed up into the 60's around lunch time, the car cranked. It won't crank when cold, I've figured that much out. I drove it to the dealer and we'll let it sit overnight to see if they can re-produce the problem, so they can diagnose while it's not cranking.

Scanner is not showing any new codes.

The 60K mile service coming up, and the possibility of automatic transaxle failure in the future has gotten me thinking. I haven't ever had a bit of trougble with the auto tranny, but I've read report after report of people who have. I have kept mine flushed and serviced.

I love the 35MPG highway but I need a reliable car. So it may be time to trade it in on a new(er) manual Accent or another small car.

Sometimes it is possible that two, or even more separate problems exist, simultaneously, and that you must fix them all, to get the required results.

It is not always "one thing, or the "other"...sometimes it's "one thing, and the other thing also"...:whistling:

Right..

The fuel pump checked out fine

The starter, alternator, battery are all fine. It's just not getting spark when it does this.

We're thinking coolant temp. sensor.

Hopefully (and my fingers are crossed), it will refuse to crank for the dealer tomorrow morning after sitting outside overnight in the 36 degree weather.

Good luck mate, sounds like a very annoying problem.

I only got my accent on sunday, and dont know much about modern cars, but it sounds like its not sparking- maybe it could be ignition coils?
