4 hours later, and I go to pick up the G. It starts up on the first try!.

The first whirr from the starter sounded a little weak, and then returned to a normal starting sounded, then ignotion. I'm beginning to suspect that the battery may be the culprit, and will get it tested again.

In the meanwhile, I will still welcome any comments or ideas from fellow G35Drivers!

I am reaching out for help and ideas to resolve a fairly recent starting problem I've been experiencing. To provide a comprehensive view of the issue, I'm going to go into detail, please bear with me...

About 6 months ago, in the middle of the day, the car wouldn't start right up. The starter engaged but sounded like it was spinning almost freely without much load, but the car would not start. After a few tries the car started normally and I was on my way. Since then, this has happened about twice a month, but since it always started, I didn't worry too much. It is after all a 12 year old car with 195,000 miles.

About 3 months ago, even though the battery was just a year old, I still went in to AutoZone for them to test it. It's still good and they tested the charging/starting system and everything checked out. So I bought a new starter, and only just installed it last month. But I'm still getting the false start every couple of weeks or so.

This past Thursday, ran out into the car during rain, and the car gave me the same false start, this time it kept cranking but not starting. So I played with turning the key at different intervals and different durations. After two quick twists on the key, so the stater engaged, disengaged and engaged again, all in less than a second, the car quit cranking. Sounded like a dead battery, or something more serious. "Damn!"

Called AAA, battery tested good, but still no cranking. Called for a tow truck. While waiting, tried to crank every 10-20 minutes so see if I could get a start going. Still sounded like a dead battery. After a 3 hour wait, the tow truck came, and I suggested that we try a jumpstart before he actually hooked me up... no problem... while I was getting the cables ready, the driver asked if he could turn on the ignition to see what lights were showing on the dashboard. And what do you know... the G started right up.

After a 40 minute drive home, I shut the car off, and it would not start again. Slow dead battery cranking sounded. After an hour, I tried again and it started up.

Friday... I did not go anywhere but did start the G to move it out of the garage into the driveway. Left it there for a few hours, then back in the garage. Each time I started it and turned it off, and back on again several times to see if maybe the battery was draining quickly. No problem.

Saturday (today) drove to Autozone to pick up sparkplugs, although I currently have NGK Iridiums installed 15 months and 25K miles ago, I figured it couldn't hurt to change them again. Started fine. Stopped at the grocery on the way home, spent about 30 minutes inside. Come back out and... no start... dead battery slow crank. Got a lift home for my Sequoia and brought my multimeter. Battery at 12.55v, after a few tries at cranking again (slow dead battery sounds), the battery is down to 12.2v. So it doesn't seem to be the battery right? Left the G there and will go back in a few hours to try to start again and attempt with jumper cables as well.

Any ideas anyone?


- thought it might have been a problem with the anti-theft chip in my key, so I put my usual key on the rack, and started using my spare key that's looks new... no change.
- looked for codes from the computer, only a P1706 (park neutral switch) that's been on and off for the last 8 years without any outward issues.
- it was suggested that the camshaft position sensor and/or crankshaft position sensor might be the culprits. The car shutting off while driving seems to be a common symptom of this, but I don't get that.

At this point, I've not found any potential solutions from the numerous online searches I've conducted. And to bring the G to a garage for a problem that's as intermittent as this, just frustrates both me and the mechanic, not to mention my wallet.
I do not have a regular mechanic, since I do almost all maintenance myself, so do not know of a good G mechanic anywhere close to me.

If you've spent the last several minutes reading this post, I do appreciate the time you spent doing so. If you can provide the solution, or any ideas that I can try, I would be immensely grateful. Thanks in advance!
