2001 Accent will not start! - 3/3/2008 2:31:42 PM    cstephen   Posts: 34 Joined: 9/24/2007 Status: offline 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 _____________________________ '01 Hyundai Accent GS Hatchback Noble White 55,000 miles Automatic White Faced Gauge Cluster 1.6L DOHC - 35.5 MPG highway Post #: 1

RE: 2001 Accent will not start! - 3/3/2008 5:21:05 PM    ken99   Posts: 399 Status: offline While in the hmaservice site, select the 1.5 SOHC engine.  Drill down: Fuel System => Engine Control System => Crankshaft Position Sensor (CKPS) => Troubleshooting Has a poor picture, but describes where it is located (look on the bell housing end of the engine).  Explains diagnostics if you are handy with an ohmmeter.  I think this is the same setup on a 1.6 DOHC engine.  These are fairly easy to access and replace compared to other Hyundai engines that have the sensor buried under a timing cover.

RE: 2001 Accent will not start! - 3/3/2008 8:30:38 PM    ken99   Posts: 399 Status: offline If scroll down the window on the right side, there's a section that covers testing the sensor with an ohmmeter.  On a good sensor, you should measure resistance of "0.486 ~ 0.594kΩ at 20°C (68°F)" between the two terminals.  No fuel and no spark are symptomatic of a bad crank rotation sensor.  If the ECM does not detect that the crank is turning when the starter engages, it will not activate either the fuel or ignition systems. I've just re-read you first posting.  If the starter itself is not turning, then you have another problem not related to the CKPS.  So how did you finally get the car started for the 3 events you cite?  When you mean "not cranking", is the starter motor turning but not engaging the flywheel or is the starter motor simply not respond when you turn the key?

Is the Crank Rotation Sensor the same as the Crankshaft Position Sensor? Bear with me, this is my first Hyundai and I'm totally new to the 1.6L engine.  I've driven an old Chrysler with a 2.5L 4Cyl for the last 7 years (my backup car) and it's quite different than this engine. _____________________________ '01 Hyundai Accent GS Hatchback Noble White 55,000 miles Automatic White Faced Gauge Cluster 1.6L DOHC - 35.5 MPG highway (in reply to cstephen) Post #: 8

Yes, I use both terms and use them interchangably.  Besides Hyundai, I currently have Fords and Nissans in my pesonnal fleet and different manuals use variations of these terms.  Replace the Crank Position Sensor.  I am surprised that your check engine light is not on or that a scan hasn't produced error codes with this sensor problem.

Thanks. _____________________________ '01 Hyundai Accent GS Hatchback Noble White 55,000 miles Automatic White Faced Gauge Cluster 1.6L DOHC - 35.5 MPG highway (in reply to ken99) Post #: 10
