2007 V36 - Suspect Starter Motor, Where To Go?

Hey all!

I noticed some problems starting up my 2007 V36 and thought it was the battery. Took it to Super Cheap Auto in Yarraville, Vic and they used their battery tester on my car (big shout to those guys - very helpful! - I almost went and bought a battery I didn't need).

The original 2007 battery isn't in the best condition, but it's still fine. The Century Test Tool said 'check starter motor' and showed it wasn't putting out enough power.

So my question... I live in inner Melbourne. Haven't had a mechanical problem with my car yet (great Nissan reliablity!) so am not sure where to go.

There is a Auto Elec just up the street - but obviously they won't know the car well. There is also City Nissan close by, but they might want to sell me a starter motor that I don't need.

Where would you guys take it?

Starter motors aren't a dark art and it's more likely a starter motor will fail rather than a component in your IPDM.

Given the test results, I'd say the starter solenoid on the motor has either died or just the positive feed into it isn't making good contact due to the bolt shaking loose for whatever inexplicable reason. I remember the solenoid in my old Maxima dropped its guts after 17 years of excellent service. It was easy to start cold but not immediately after driving (ie. hot).

Hopefully someone from your neck of the woods will chime in with their recommended auto sparky.

Yup, I have had batteries that have held volts, but wouldn't provide a bees dick of amperage. Perhaps borrow a battery out of something just for a test. Then you can really rule it out.

It could well be the battery still, these cars have way too much electronics in them to like even a slight voltage drop.

What is it doing on startup?

Basically, I'll push the start button, and it'll start up (it revs up automatically) and then after about a second revs drop to 0 and it conks out. Not all the time, but maybe 1/10 starts, and esp if I have the heated seats on. If this happens, I usually just start it and give the throttle a little squirt and it's fine.

Definitely doesn't sound like a battery nor starter motor problem. You'll need a mechanic for this one, not an auto electrician. Scotty's started you off on the right path. Take it from there.

Sounds like it just needs the throttles cleaned, or perhaps there is a vacuum leak? Then you could try a throttle relearn.

What engine do you have?

Can this problem cause the Century Battery Tester readout to report 'check starter motor'?

I have a 3.7L. I also have some throttle body cleaner...

It could, it is only saying the battery voltage is fine and something else (starter) is at fault.

If you plan to attack the throttles on your own, make sure you don't open the throttle plate when you clean them, and don't turn the key on until you have plugged them back in.

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
