I am having a problem with my Infiniti I30. It will turn over and shutter, but will not start up. The battery is charged and the gas tank is 3/4 full.

The video below is how the car is acting at the present time. We did go through a weather change from close to 10 degrees to 40 degrees in the last few days since the last time that the car was started. The car didn't have power issues leading up to to this, nor were there flickering of any electrical components.

Any help or suggestions would be extremely helpful. Thank you.




Update:
I read the error codes and I am getting a P0325. This is Knock sensor circuit malfunction.

 

I don't have time to watch the video, but it sounds like you have the same issue every single 4th gen Maxima has. Poor grounding. Get some good ground cables and battery terminals. I made my own cables out of 1/0 SGX Cable. Crimped good lugs on them, put some heat shrink on the ends and replaced all of the original ground cables with them. I also added one leading from the long bolt that goes to the starter and screwed it in the chassis where the original one is screwed in. I done this almost a year ago and have not had a hard start since.

 

Is the P0325 the only code? The knock sensor usually doesn't have any effect on starting.

After watching your video, it seems like not all the cylinders are firing. When was the last time the spark plugs were changed?

Here is the op's video...

Welcome to Maxima.org. Are you the do it yourself DIY type? Do you have metric tools in 10mm, 12mm, and 14 mm sizes.

+1 the Knock Sensor code is what we call a Ghost Code. It usually accompanies another code or problem.

The video reminds me of my 99 model trying to start back in February. Notice any similarities?

Time to start verifying fuel and fire.. Pull the plugs and look for any differences between cylinders. Show us a picture if you can.
Keep a record of plug and the cylinder. It will be important to trace a blackened or wet plug back to the cylinder with a fuel or fire problem.

In my case I had uncontrollable flooding that was caused by broken injector pintle caps in addition to a few other mid-life maintenance needs.

 

I have a 98 I30. Before you start anything, clean off both of you crankshaft position sensors. Then proceed with other diagnostics. I had bad starting problems until I did a cleaning. They were caked with road gunk. With my car that was all it took but you might have more problems.

 

Check the basics. Do you have air fuel spark and exhaust. And then go from there
