How to improve cold start timing in NA8

Call me a perfectionist but coming from a honda, my previous cars used to start after turning the key and car cranks once and it's on.

On the NA8 I have to hold the key for 3 cranks before it starts, car has yet to not start and excuse my question if that's how theyre supposed to work but if this isn't the case and it should start after the first crank, how do I improve this timing on my car? Is there something I can check or clean?

There's a new new nrma sealed battery in the boot.

Was a serious question people... I'm surprised by the answer (3 cranks is the norm) as I was when told there's no CEL on the car...

Be gentle I have much to learn

Cel were dríven my emissions as much as anything else I think.

Probably something to do with the CAS needing to do a full revolution so the ecu know which cylinders to fire.

It has a single tooth to allow the ecu to find top dead centre, some cars have up to 36 teeth one for every 10 degrees of 360*. When you have only the top centre tooth for one cylinder the engine needs to cycle to the next full top cycle on the next firing cylinder. The most turns this can be on a 4 cylinder is 3 before firing.

Its just 3 turns its all good.

Interesting to know. Over engineering a solution to a problem that doesn't really exist lol.

Funny how most people who join this forum find it extremely helpful and welcoming.

Yet you come here telling everyone they are wrong, bogans, thief's etc etc and aren't happy when no one agrees with your point of view. Going as far to claim where all stupid people who don't actually modify anything and just sit around out cars and talk sh*t.

Given you've now turned to personal sledging as your first post in a thread I can only assume you are infact a troll and you've got tired of the stupid Sydney drive / fake brakes are ok / unequal length tuned header debate.

I have reported the above comment to administration hopefully the thread can be locked before it becomes a useless sh*t fight.

Yep I'm a huge failure, and I never help anyone on here.

Stupid questions/trolls are funny, simple as that.

I do not know him at all.

I was temporarily offended, then read the Chinese brakes thread haha.

Back to OP, NA mx5s are getting really old, lots of things won't live up to the newer honda you've come from.
But it delivers in so many other ways :D

Sometimes I have less hate for people when I learn they have mental handicaps.

Ah the modern world, where we can simply throw out an "I'm sorry" without any thought and consider it as the great "undo" button.


Oh but imagine a world where "i'm sorry" cures all ailments by it's mere utterance, where one may be free to insult and offend at will only to say these magic words and undo all injury, where if the offended are still hurt by the words it's their ow fault "because I said I was sorry already!"


Dupain you are a farking moron, please ƒü¢k off.


I don't think you are offended and if you are then I send my apology, it was not what I intended to do.
