Hey guys,

Have had trouble starting my car only sometimes lately. Today it took me about 10 turns of the switch to get the starter motor to turn over the engne.

I get in the car, put the key in, turn it past accessories to the 'ON' position I guess, let the fuel pump go for about 5 seconds before turning the key to 'START' and nothing.... just cuts out the radio. Tried it about 7 times, then took the key out, turned it around, did the same thing, did the same thing first attempt, and then on 2nd attempt fired straight away.

Has this happened to anyone else? And what could be the causes?

Worn out ingition barrel not contacting anymore (I have no idea how it works inside the barrel)?

Starter motor contacts bad??

It used to only do it maybe once or twice at most, and only usually every 5 or so times of starting the car (it would usually strart straight away), but yesterday afternoon and today afternoon I had trouble.

Any other ideas?

Thanks,

Fixxxer

If the key goes in and turns to start normally the first time before flipping it then its got nothing to do with the key or barrel. However commodores use an anti theft device in the key head that flipping the key sometimes helps, but thank god you dont have a commonwhore!

Most likely a starter problem. To be safe you should get a multi meter and load test the battery. First unplug the ignitor so the car wont start. Attached the two terminals of the multimeter to the battery terminals then get someone to try cranking the engine and while its winding over watch the reading on the multimeter. If it drops below 10 volts then your battery is dieing. If not and it stays around 11-12 volts the battery should be fine and you can be more sure its the starter/solinoid causing the fault.

Battery should be fine, its a good battery, I replaced it only about 3 months ago....

It's not like the starter is struggling to start the car, it's like the power is not getting to the starter, and then suddenly i turn the key the right way or something and it fires instantly.

OK then we can rule out the battery, good. Next look at the starter & solinoid (which are combined) and earthing of the circuit. If there isnt a good earth (strap) you may aswell be not supplying enough power as its the same end result.

I had the very same problem on my car some time ago!

It ended up beeing the front + and -poles on the left side of the engine bay.

The thing was that the prior owner had connected front-lights to the +pole and that created a gap big enough for dirt getting in and ruin the connection.

Apperently the connection was good enough for panellights and such, but not good enough for the starter.

If i recall correctly i think the windows wouldnt move either...

Hope that helps!

As the brushes wear in a starter you will get an inconsistent starting patterns. But I have also seen a brand new battery off the shelf that I have had to fit to a customers car and it has had a brake in between the cells.

Do what Deren said by checking battery voltage, whilst cranking - this will give you the best indication, also check you main battery lead going to the starter - if these look ok - its time to pull the starter out, and give it to some mug they call an auto electrician :P.

Ok I will look around the starter motor and see if there is anything wrong with connections.

Next I'll check the battery and connections to the battery, but like I said this doesn't seem to be a problem as there is plenty of kick to start the car when the starter works, and this has been a problem ever since I got the car a year and a half ago (with a different battery).

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
