So the engine is cranking but it won't start when this is happening?Was the ecm replaced to try and resolve this issue?
Ok, and it is in fact cranking just not starting?
Is the check engine light on when it is running?
I think the place to start here is with a throttle relearn. You can do this manually but need to make sure you follow the instructions to the letter. The throttle may not be setting correctly on your first start of the day.
Here is the procedure, please try it and let me know.
Nissan Relearn1 Perform "Accelerator Pedal Released Position Learning".A Make sure that accelerator pedal is fully released.B Turn ignition switches ‘ON’ and waits at least 2 seconds.C Turn ignition switches 'OFF' wait at least 10 seconds.D Turn ignition switches ‘ON’ and waits at least 2 seconds.E Turn ignition switches 'OFF' wait at least 10 seconds.2 Perform "Throttle Valve Closed Position Learning”.A Make sure that accelerator pedal is fully released.B Turn ignition switches 'ON'.C Turn ignition switches 'OFF' wait at least 10 seconds.Note Make sure that throttle valve moves during above 10 seconds by confirming the operating sound.3 Start engine and warm it up to normal operating temperature.4 Turn ignition switches ‘OFF’ and waits at least 10 seconds.5 Confirm that accelerator pedal is fully released, turn ignition switch 'ON' and wait 3 seconds.6 Repeat the following procedure quickly five times within 5 seconds.A Fully depress the accelerator pedal.B Fully releases the accelerator pedal.7 Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the MIL stops blinking and turned ON.8 Fully release the accelerator pedal within 3 seconds after the MIL goes off.9 Start engine and let it idle.10 Wait 20 seconds.11 Rev up the engine two or three times and make sure that idle speed and ignition timing are within the specifications.12 If idle speed and ignition timing are not within the specification, the result will be incomplete. In this case, more test needs to be done.
Ignition timing is 15 btdc, you can only read that with a scan tool.
idle speed is roughly 700 rpms with the a/c off. +- 50 rpms
Do you need further assistance with this?
Thanks for the info, it's odd that it would only happen once a day with the same key. Honestly I have never seen that issue.
