Cranking no start, no OBDII codes

Welcome to 2CarPros.

Have you checked to see if there is spark to the engine? The easiest thing to do is see if it will start a couple seconds using starting fluid. If it does, then it is a fuel related issue. If it doesn't, then ignition is the first suspect.

Does it sound different when it is cranking?

Take a look through these links to see if they are helpful.

As far as not having the port to check fuel pressure, you have to open the fuel line where it connects to the fuel rail and place a T connector there. Here is what the manual says. It indicates the specific tool needed. You can look up the part name and number to see it.

On vehicles not equipped with a Schrader valve, use the Rotunda Fuel Pressure Test Kit #134-R0087 or equivalent.

Let me know what you find. If it sounds odd when you try to start it, the timing chain may have broken or jumped. However, most commonly, spark is lost due to a bad crankshaft position sensor. When they start going bad, they are affected by heat. If it was at an idle with the AC running, that could be the problem. If you try the starting fluid and it doesn't even try to start, then spark is lost and chances are the sensor is the problem.

If you have a live data scanner, plug it in and crank the engine while watching for an RPM signal on the scanner. No RPM signal, replace the sensor.

Here are links that explain what the sensor does, symptoms, and in general how it is replaced:

Welcome back:

Okay, that is as normal as it gets, so we have eliminated that possibility. Have you physically checked to see if there is spark? Since it doesn't start with starting fluid, I suspect no spark, but did you confirm that?

Next, even the camshaft position sensor can cause a no start. The computer uses this sensor for fuel injection pulse and ignition timing. Since you have confirmed the crankshaft sensor is good, this is my next suspect. If you still have the live data scanner, see if there is a CMP signal when cranking.

Also, if you could verify if there is or isn't spark, that would help.

Take care,

Welcome back:

Are you still getting an RPM signal? If so, then we have to check if there is a problem with where all coils are spliced together. If you look at pic 1, it shows the splices. Pic 2 explains location. If there is no signal (RPM), replace the crankshaft position sensor.

If you have the RPM signal, check the splice. If it is good and the crank and cam sensors are good, there could be an issue with the powertrain control module (PCM).

Let me know.
