No spark no start

Welcome to 2CarPros.

The first suspect is a failed crankshaft position sensor. Take a look through these links.

The best way to test if the sensor is bad is using a live data scanner and checking for an RPM signal when cranking. If there is none, suspect the sensor needs replaced.

I noticed you listed again. I wrote duplicate on that posting. I need to know the correct model year to help provide more detailed information. The Sorento wasn't offered until 2003.

Let me know.

I am sorry about that, it's a 2004 model and thank you for helping me.

Welcome back:

No problem. I just wanted to be sure. Now, if you can get your hands on a live data scanner, you need to check for an ignition signal from that sensor or an RPM signal while cranking the engine. We need to be sure this is the problem, because it requires removing the timing belt cover to access the sensor. The first picture I attached shows the sensor.

If you use a scanner but get no RPM signal, first try moving the wiring around to the sensor. It may have a bad connection.

If that doesn't help, next I need you to access the sensor and unplug it. You will need to check for a signal from the (PCM ) power-train control module. See picture 2 for specs that should be found. For this procedure, you will need to use a multi meter. Here are a few links to help you through the process:

Now, if you have no RPM signal and the aforementioned electrical test is good, replace the sensor. The hard part here is the drive belt needs removed, then the crankshaft pulley, and then you can remove the lower timing chain cover.

Picture 3 is a good picture for locating the sensor I am referring to. It is identified as a crank angle sensor.

If you need help or have questions, let me know.

Take care,
Joe

Hi Joe, thanks again. it has started but would not rev pass 3,000 rpm. what can I do now?

Welcome back:

Okay, with that in mind, I need you to check both the crankshaft sensor and the camshaft position sensor. If the camshaft sensor does not operate correctly, sequential injection is may not occur and the engine may stall or run irregularly at idle or fail to accelerate normally. I have a feeling it is one of the two items I mentioned.

Here are the directions for testing this sensor. Also, this sensor is located at near the timing belt too, so the directions are similar to the crankshaft sensor.

Picture 1 shows location, picture 2 is a circuit schematic, and picture 3 shows specs for harness inspection.

Let me know what you find. Also, if the check engine light is staying on, you need to scan the computer for diagnostic trouble codes. That will point us in the right direction.

Take care,

Joe
