Will not start

Hi and thanks for using 2CarPros.com.

We need to check a couple things before we dig in. First, make sure the connection is at the fuel pump is in good condition and not damaged, loose, or corroded. I attached a picture for you to see its location.

If that checks good, see if there is power to the pump. Here are directions for using a test light:

For wire testing:

Next, confirm there is spark for sure. Here are the directions.

If there is power to the fuel pump and you have good spark, you need to confirm the fuel pump pressure is within the manufacturer's specs. Here is a link showing how that is done:

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

Here are fuel pressure directions specific to your vehicle: Pictures 2, 3, 4 correlate with these directions.

FUEL DELIVERY SYSTEM

Fuel Pressure Test

1. PREPARING
1. Open the service cover under the floor carpet.

2. RELEASE THE INTERNAL PRESSURE
1. Disconnect the fuel pump connector.
2. Start the engine and wait until fuel in fuel line is exhausted.
3. After the engine stalls, turn the ignition switch to OFF position and disconnect the negative (-) terminal from the battery.

Note: Be sure to reduce the fuel pressure before disconnecting the fuel feed hose, otherwise fuel will spill out

Fuel Pressure Special Service Tool

3. INSTALL THE SPECIAL SERVICE TOOL (SST) FOR MEASURING THE FUEL PRESSURE
1. Disconnect the fuel feed hose from the delivery pipe.

Caution: Cover the hose connection with a shop towel to prevent splashing of fuel caused by residual pressure in the fuel line.

2. Install the Fuel Pressure Gage Adapter (09353-38000) between the delivery pipe and the fuel feed hose.
3. Connect the Fuel Pressure Gage Connector (09353-24000) to the Fuel Pressure Gage Adapter (09353-38000).
4. Connect the Fuel Pressure Gage and Hose (09353 41 00) to Fuel Pressure Gage Connector (09353-24000).
5. Connect the fuel feed hose to the Fuel Pressure Gage Adapter (09353-38000).

4. INSPECT FUEL LEAKAGE ON CONNECTION
1. Connect the battery negative (-) terminal.
2. Apply battery voltage to the fuel pump terminal and activate the fuel pump. With fuel pressure applied, check that there is no fuel leakage from the fuel pressure gauge or connection part.

5. FUEL PRESURE TEST
1. Disconnect the negative (-) terminal from the battery.
2. Connect the fuel pump connector.
3. Connect the battery negative (-) terminal.
4. Start the engine and measure the fuel pressure at idle.
Standard Value: 343 Kpa (3.5 kgf/cm cm, 49.8 psi)

Incorrect Pressure

If the measured fuel pressure differs from the standard value, perform the necessary repairs using the table below.

Pressure Drops

5. Stop the engine and check for a change in the fuel pressure gauge reading.
After engine stops, the gage reading should hold for about 5 minutes
Observing the declination of the fuel pressure when the gage reading drops and perform the necessary repairs using the table below.

6. RELEASE THE INTERNAL PRESSURE
1. Disconnect the fuel pump connector.
2. Start the engine and wait until fuel in fuel line is exhausted.
3. After the engine stalls, turn the ignition switch to OFF position and disconnect the negative (-) terminal from the battery.

Note: Be sure to reduce the fuel pressure before dIsconnecting the fuel feed hose, otherwise fuel will spill out.

7. REMOVE THE SPECIAL SERVICE TOOL (SST) AND CONNECT THE FUEL LINE
1. Disconnect the Fuel Pressure Gage and Hose (09353-24100) from the Fuel Pressure Gage Connector (09353-24000).
2. Disconnect the Fuel Pressure Gage Connector (09353-24000) from the Fuel Pressure Gage Adapter (09353-38000).
3. Disconnect the fuel feed hose from the Fuel Pressure Gage Adapter (09353-38000).
4. Disconnect the Fuel Pressure Gage Adapter (09353-38000) from the delivery pipe.

Caution: Cover the hose connection with a shop towel to prevent splashing of fuel caused by residual pressure in the fuel line.

5. Connect the fuel feed hose to the delivery pipe.

8. INSPECT FUEL LEAKAGE ON CONNECTION
1. Connect the battery negative (-) terminal.
2. Apply battery voltage to the fuel pump terminal and activate the fuel pump. With fuel pressure applied, check that there is no fuel leakage from the fuel pressure gauge or connection part.
3. If the vehicle is normal, connect the fuel pump connector.

Hi again:
It does. I attached a wiring schematic of the system. Also, here are the relearn directions for the key and password.

Key registration and correction. See pictures 1, 2, 3 which correlate with these directions:

KEY REGISTRATION AND CORRECTION
1. INITIAL REGISTRATION METHOD
2. REGISTRATION CORRECTION FOR MASTER KEYS
In cases when the master key is lost or where a new set of master keys need to be produced, it can be achieved using two methods.
1. Using ID key
2. Using password
When the customers lost the ID key, new master keys can be registered by using Hi-scan only. ID key can not be corrected and reproduced.

NOTE: Once the password is mis-registered, it is impossible to register new password during 10 seconds regardless of ignition ON/OFF.

When the new master keys have been registered, the codes for existing master keys are all cleared.

The password should consist of 4 numbers among ten (0-9) numbers

Pictures 4 and 5 are the wiring schematic for the immobilizer.

I hope this helps.

Let me know,

Hi again.

If the crankshaft position sensor is bad, you will not get spark. I missed that you mentioned it later because the first post said it had spark. In my mind, we still had spark. Sorry.

Let me know how things turn out.

Hi again. To be honest, that sounds like a camshaft position sensor issue. There are two of them on your vehicle. See attached picture. However, I wouldn't arbitrarily replace them until you are sure there is an issue. Has the check engine light come on when this happens?

Let me know.

Joe

Scan the computer. There may be a saved code. As far as limp mode, you get second gear and no other. It is just to "limp" the vehicle to safety.

Hi again. I read back through the posts. The sensors I am referring to are the camshaft position sensors. The one you replaced was the crankshaft position sensor. The 1372 indicates an issue with the crank sensor (the one you replaced). Either the sensor is not seated correctly or there is a wiring issue at the sensor. I have attached three flow charts that describe how to check the sensor.

DTC P1372 Segment Time Acquisition Incorrect

DESCRIPTION
Misfire induces a decrease of the engine speed and causes a variation in the segment period. Therefore misfiring detection is based on the observation of this variation of segment period.

Let me know if this helps.

Joe

Hi again. The idea that it runs good cold and then there is a problem when it warms up honestly sounds like a crank sensor issue. I realize you replaced it, but you may have gotten a bad one or inexpensive one. What trouble code is now stored?

Welcome back.

There is not a transmission sensor that would cause what you have described. Is it possible for you to have someone video what is happening?

Welcome back.

Since it is only related to one cylinder, chances are it is the coil itself. However, make sure the plug wires are in good condition, not arcing, and make sure there isn't a valve cover leak. There are seals in the spark plug wells that can allow the well to get excessive oil in them. This can result in a misfire.

Let me know what you find or if you need anything.

Take care,
Joe
