Had a few annoying little car issues lately , including not being able to remove Key from ignition and once even the car wouldn't start (but would turn over fast) and we were discussing some of these at Pyrennies gathering yersterday.
It seems many have had an annoying issue as
well so its time for some tips I thought.
Then this morning we had occasion to drag out my DRZ400 (trail bike) and it hasn't been started for a few weeks and you guessed it, it didn't want to fire up just when we were in a hurry.
Couldn't find my can of "Start U Bastard" then No1 son walks past, grabs can of Super cheap brand WD40 and wow , didn't she start in a hurry then.
These days we are more sophisticated and usually start our fires with a gas blowtorch but a while back we used WD40 and I remember that some would have the Super Cheap version instead, and instead of being a nice controlled flame it used to sputter more violently and eratically - so I'm guessing thats why it started the petrol engined bike so instantly.
Anyway it works seriously !

You ought to try some Carby & Throttle Body cleaner in the pressure-pak, if you want to see some real fire-up action!
About on a par with injecting nitrous!
Toluene, Acetone, and various volatile hydrocarbons as propellant, makes that Ether look tame!
You don't want to get a good sniff of it yourself, either - I reckon a sniff of the stuff would dissolve more brain cells than a carton of XXXX!

Robin, I use a sniff of powdered graphite annually in ignition lock mechanisms.
The Toyotas seem to suffer from pretty severe wear in the ignition lock and keys after about 120-140,000 kms.
We had trouble with the old family Camry (2001 model), with the ignition lock just jamming up occasionally at 120,000 kms.
It took a lot of jiggling and wriggling, and then it would let go and work just fine for a week, when it would lock up again.
Examination of the key found some serious wear on it. I replaced the key with a new one - and hey presto, problem solved.
I'd even bought a new ignition lock assembly in preparation for replacement.
Solved the problem completely on Saturday - bought a new Camry with keyless entry and operation!
That should provide us with some different fun when it all stops working!
Cheers, Ron.

MY thoughts too Ron but this was really one out of the blue that didn't occur to me.
Picture this , pulled up in into Knox city
carpark in middle of big storm and key wouldn't come out.
Rock steering wheel etc and jiggled key all over the place and still nothing. Rotated key , started the car drove in circle playing with steering and nothing so turned engine off again and it was now hailing, couldn't just walk away from car with key in it and weather was to bad to open bonnet and disable car some other way. Made some coffee (cars always ready for short trip) then casually touched key and it almost fell out - weird !
Drove
home checked key against spare and noticed they were not exactly the same - spare key worked
well , but 4 starts later spare key did same trick stuffing up my theory about just getting a new key cut .
So what was it ? - 2 hours with workshop manual revealed that Nissan Patrol key mechanically pushes a 1 meter long cable with a nylon inner. The cable goes down to the auto transmission and effectivily stops a shift lock mechanism from moving .
I.E. You can't take key out unless in park , and slack in cable didn't quite operate the "I'm in park" switch.
Even though I had no choice if I wanted a 4800 Gu please stand by while I kick myself again for buying an automatic.

Automatic everything.
Even includes automatic key retention!

The biggest killer of ignition locks is too much cr@p on the key ring, should always just have no more than 3 or 4 keys on it!

That was a td5 disco trait. They'd wait until you were at the bottom of a
boat ramp or below the high tide mark at
the beach then the barrel would die - speaking from experience.

Hard starting with diesels can sometimes be sheeted
home to inadequate cranking speed.
You need good cranking RPM to get a diesel to fire up quickly.
You can wind a 24V diesel over on 12V - and it sounds O.K. - but it will never start, because the cranking RPM isn't high enough to create fuel ignition.
So it's important to ensure batteries, starter motor, and particularly wiring and connections, are up to scratch to ensure adequate cranking speed.
I've seen dirty battery terminals lower cranking speed enough to cause hard starting.
Cheers, Ron.

Ron, if you go the other way and stick 24v into a 12v system you get some action..lol, plus smoking starters, melting wires, but have started a stubborn a#@$@ of a thing sometimes in desperate situations. and got away with it.
Cheers.

In
sedan racing in the 60's, it was common to fit 12V Holdens with the 6v starters from the FX/FJ era. Spun over the high-compression engines like there was no tomorrow.

There are a hell of a lot of diesels out there with completly non functioning glow plugs.
In our warmer climate they will start fine.
Untill the battery gets a bit sad or in cold weather.
If your diesel needs a lot of cranking speed...
check your glow plugs.
A few years ago...I replence the battery in
mine because it was not starting
well on cold mornings......new battery fixed the problem.
I checked the glow plugs a short while afterward.....not one working.
Starts very promptly and eailsy after that.
Listen to the diesels of others......if it cranks and cranks, before it starts.....betya there is a glow plug problem.
cheers

Yer right there,
Ross - seen a few broken rings from an overdose of Aerostart!
I was in Bunnings this afternoon and they were selling cans of Butane gas (refills) for $4.40 for 4 cans!
Now, that would be some pretty cheap, "start ya bastard"!
All you need is a spray can cap, and you've got a ready-made can of kick-start!
Sort of make ya wonder how they can charge $10 or $12 for an equivalent can of go-juice?!
Cheers, Ron.

Did you know that Bunnings charge $16 for a can of plain compressed air?

Is it "plain" air Mike? Or Chinese air with 'additives'.
