Crank will not start

As far as the temperature gauge, it sounds like there is a short to power. Do me a favor. I need you to test the oil switch. Here are the directions and the attached pic correlates with the directions. If you need help, let me know.

1. Remove the YEL/RED wire (A) from the engine oil pressure switch (B).
2. Check for continuity between the positive terminal (c) and the engine (ground). There should be continuity with the engine stopped. There should be no continuity with the engine running.
3. If the switch fails to operate, check the engine oil level. If the engine oil level is OK, check the engine oil pressure. If the oil pressure is OK, replace the oil pressure switch.

Next, I need you to check for spark and fuel to the engine to help determine why it won't start. The easiest thing to do is see if it starts for a couple seconds using starting fluid. If it does and then stalls, then we know it's a fuel related issue. If it still doesn't, then it's likely ignition related.

If you feel uncomfortable using starting fluid, here are two links that explain how to check for both:

Let me know what you find.

Let's do two things. First we need to check for codes. I suspect we have an issue when the coolant temperature sensor is faulty telling the PCM that the engine is hot and it is not dumping the correct amount of fuel so the engine will start. If we have codes then we can track down that issue and is not, we can just go after the coolant sensor on our own and then once that is fixed we can retest the starting issue.

Here is a video that covers the basic things of a no start but again, let's go after the coolant temp sensor first and then we can address the no start if that does not fix it as well, which will be checking for spark and fuel.

Hi,

If it starts with starting fluid, replace the sensor to see if that takes care of the problem. Is the vehicle able to be restarted without the use of starting fluid?

Joe

The way I understood this was the temperature gauge issue happened at the same time as it started to not start. If this is the case then I would think the PCM is cutting the injectors due to it thinking the engine is overheating. If these issues are related, then doing as Joe stated of replacing the sensor would fix both issues.

However, if it doesn't then we can chase the fuel issue because clearly it is not getting fuel causing the no start.

While the sensor is the most likely cause of this, it could be a shorted wire. If it were me, I would replace the sensor and go from there. They are pretty cheap which makes it worth while to just swap it out.

Here is the info on the sensor. Let us know what happens. Thanks

Please let us know what you find. We are interested to see what it is.

Sorry. It is circled in this attachment. Called the ECT for engine coolant temperature sensor.

It is actually behind the black electrical connector. I pointed in red to the wiring for the sensor.

Let us know if you still can't find it and we will see if we can get more detail.

Hi,

Here are the directions for replacing the sensor. The attached pic correlates with the directions.

1. Remove the air cleaner.
2. Disconnect the ECT sensor 2P connector.

3. Remove the ECT sensor (A).
4. Install the sensor in the reverse order of removal with a new O-ring (B).

Let me know if this helps. Also, the sensor is below the component you mentioned. You shouldn't need to remove it.
