Cranking but not starting

Hi,

There was a technical service bulletin related to the key not being detected. Take a look through this and let me know if it mirrors what you are experiencing and if the diagnostics help.

See the attached pics.

Let me know.
Joe

Hi,

You are very welcome. Let me know what you find or if you have other questions.

Take care,

Joe

Hi,

Check pin 3 again and see if there is power when you actuate the window switch.

Let me know.
Joe

Hi,

To check things at the PCM, you need to be specific. The PCM controls many different things, so to say check it is really too general. I hope that makes sense.

Update: I just realize I am working on a few of the posts you listed. Sorry about that. I saw the name and thought it was related to the window problem on the other vehicle.

Joe

Hi,

Since there isn't one specific test for the PCM, let's start in another way. Since the vehicle cranks but doesn't start, have you checked to see if it is an ignition-related issue? Is there spark to the plugs?

Let me know.

Joe

Okay, let's start at the beginning. Here are the diagnostics for testing the ignition coil and power transistor. Do this and let me know what you find.

If you have already done this, let me know.

IGNITION COIL WITH POWER TRANSISTOR

CAUTION: Do the following procedure in the place where ventilation is good without the combustible.

1. Turn ignition switch OFF.
2. Disconnect ignition coil harness connector.

Pic 1

3. Check resistance between ignition coil terminals as follows.
4. If NG, Replace ignition coil with power transistor.
If OK, go to next step.

5. Turn ignition switch OFF.
6. Reconnect all harness connectors disconnected.

Pic 2

7. Remove fuel pump fuse in IPDM E/R to release fuel pressure.

NOTE: Do not use CONSULT-II to release fuel pressure, or fuel pressure applies again during the following procedure.

8. Start engine.
9. After engine stalls, crank it two or three times to release all fuel pressure.
10. Turn ignition switch OFF.
11. Remove ignition coil harness connectors to avoid the electrical discharge from the ignition coils.
12. Remove ignition coil and spark plug of the cylinder to be checked.
13. Crank engine for five seconds or more to remove combustion gas in the cylinder.
14. Connect spark plug and harness connector to ignition coil.

Pic 3

15. Fix ignition coil using a rope etc. With gap of 13 - 17 mm between the edge of the spark plug and grounded metal portion as shown in the figure.
16. Crank engine for about three seconds, and check whether spark is generated between the spark plug and the grounded part.

Spark should be generated.

CAUTION:
- Do not approach to the spark plug and the ignition coil within 50cm. Be careful not to get an electrical shock while checking, because the electrical discharge voltage becomes 20 kV or more.
- It might cause to damage the ignition coil if the gap of more than 17 mm is taken.

NOTE: When the gap is less than 13 mm, the spark might be generated even if the coil is malfunctioning.

17. If NG, Replace ignition coil with power transistor.

CONDENSER-1
1. Turn ignition switch OFF.
2. Disconnect condenser-1 harness connector.

Pic 4

3. Check resistance between condenser-1 terminals 1 and 2.

Resistance: Above 1 MOhm at 25 degrees C (77 degrees F)

Hi,

This showed up in my inbox which normally indicates you replied. However, there is nothing listed. Did you need help with anything?

Joe

Hi,

A 2006 has the standard OBD2 protocols. Is that what you mean? As far as specifics, all companies have their own proprietary programming.

Let me know if that answers your question.

Joe

Hi,

Sorry. Nissan refers to it as the Consult. I believe it is now version 3 (Consult III).

Let me know if that is what you needed.

Joe
