I have a 2004 huyndai Santa Fe. The belt tensioner broke on the timing bet. I Found another motor to replace the one I had. All was well then it started stalling, misfiring and dying. I had a mechanic read the codes. Each time it would give me segment timing incorrect which the suggestion was to replace the Crank Position Sensor. I replaced it. Now the car will not start. It will turn over but will not start. I took the new sensor out twice and replaced with another new one. It still wont start. What would be the issue? Do I need to clear the codes or am I haveing a run of bad parts?

Are you able to restart with the original sensor?
Did you check the pickup point of the sensor for damage?

The old sensor was damaged and burned and will not work. The one I replaced it with that would act up after it got warm was returned the parts house. We have checked the contact point on the block to see if there is any obstruction. I have someone coming over today to ome out the wiring harnes to see if there is a broke wire and a voltage probe to make sure were getting the right voltage.

Thanks for all your help.

I have the vehicle listed bone. Just bought a brand new battery and it turned over once I cut it off started it again and it sputtered and shut off 3 times then went back to not starting at all. What can the problem be?

I was mistaken on the code. It was a P0335. It read Crankshaft Possition Sensor. We ran a voltage test and omed it. We are getting fire to the sensor. We are finding we are not getting fire to the coil pack. Would this sensor supply fire to the plugs?

Hi,

It can be a few different things. However, what you need to do first is determine if there is spark and fuel to the engine. Chances are one will be missing. Once determined, then we will know what system to focus on. If you have a scanner, that would really be helpful. If possible scan for diagnostic trouble codes and let me know what they are.

Now, here is an easy test. See if the engine starts for a couple seconds using starting fluid. If it does, then we know if it a fuel related issue. If it doesn't chances are it is ignition related. If you would rather, here are two links that explain how to check for both spark and fuel:

https://www.2carpros.com/articles/how-to-check-fuel-system-pressure-and-regulator

https://www.2carpros.com/articles/how-to-test-an-ignition-system

Check those two things or try the starting fluid and let me know what you find.

Take care,
Joe

It supplies a signal to the coil to fire. The crank sensor should be about 825 ohms. Across one connector terminal of the crank sensor and chassis ground key on engine off you should see 1.4 volts. Then do the same on the other connector terminal and you should see the same.

Thank you. I'm going to try the starting fluid when I get off work. But the thing I don't understand is if I jump it off it will start right up but when I cut it off and try to start it back nothing. But thanks for your help. I'll try the starting fluid this afternoon and go from there.

Ok, I went back to the same auto parts store and had this one exchanged for warranty. This is the 4th time. I put it on the car and no luck. The car still wouldnt start. I went to another parts house and got a name brand one staying away from house brands. Put the new one on the car and she fired right up. I drove my car to the parts house were I have went through 4 defective parts and told them I wanted to return and no more replacements. They had to ask me if I knew what I was doing and I told them there is the car in the parking lot with a competitors part and it is running. They gave me my money back. I want to thank you for all your help.

Okay, so when I got off of work I took the new battery back out of the truck and put the old one back in and it started right up. I also bought a code reader and no codes are popping up. This has really got me confused.

Your welcome that's what were here for you could have just checked all those sensors with a ohms meter like I told you could with a ohms meter. That would would have told you that you were getting bad parts all along.

Hi,

Actually, this most likely will make things easier. First, have the new battery load tested where you got it. If it checks good, then we most likely have a connection issue. Make sure terminals are clean and tight and inspect all wiring around the battery for evidence of damage, corrosion, or anything that can create a poor connection.

Has there been any issues since the old battery was installed?

That's good news. I suspect it was a bad connection. Chances are if it has been good that many times, it should be fine.

If something changes, let me know.

Take care and have a nice holiday.
