Well,
I`ve reset my ECM,
learned the TPS.

Still no improvement

I wonder,
Anybody ever had a problem with air in the fuel rail ?
or leacking injectors ??

It feels like simular problem

Hi Mohkraats
are you using a genuine Honda key, i have had similar problem
with an after market key also do you have any other transponder
keys nearby when starting as the aerial  could pick up the wrong key.

Hello g5guzzi,

Good suggestion.

Though not applicable in my case.
Key is original,
no other transponders near by.
Besides that,
In such case the issue should not only be present at cold start.....

But thanks anyway,

Mohammed

There are some odd suggestions here.
I've never heard of TPS causing slower starts, nor transponder faults (that ought to flash up the hiss lamp).

All things being equal I might suggest a poor battery/starter (not spinning fast enough) but what is the (service) history of the bike ?  Could it be due for valves check, have very old plugs, running on a 10-year old battery (that "appears" okay - but in daily use).

Folk (mainly in Greece) seem to have issues with fuel pumps (or maybe just the internal filters) but a pressure test is required for that (does the pump sound normal?).

A damp air filter is of concern though.

How long is 'long' cranking - my mkII has never started 'on the touch of the button' like some motors.
Only do it right - no bodging please.   Keeper of the failed stator list.   John.

Hello JM2,

Thanks for the suggestions,
Well,
plugs are new, valve clearance has just been done.
Battery is new, engine speed at crancking is perfect.

Funny thing is,
it is only after multiple hours stand-still.
When after such a s**tty start, I kill it immediately again, It doesn't take much crancking for a second start.
When I let the fule pump pump up a second time before crancking doesn't make a difference.

It has all the feel from an ECM doesn't want to start straight away. So that far, the immobilizer was a good guess ........

But anyway,
I am considering to put it for sale by now.
Have been struggling long enough, and getting fed up with this bike.

The workshop offered me to have a look at it, however, they charge me by the hour, while searching. :172:
That is a bottomless pit.

Ah, oh,
Forgot on one detail.
Well "long crancking"
Since this is an injection system, it takes slightly more crancking then a carburetor system.

Normally, its maybe half a second crancking.
In my case after a couple of hours standing around, it takes, say, two seconds cranking before it starts.
During that crancking no sign whatsoever of any combustion. As soon as it starts, it doesn't miss a beat from there on.

What about the ECT sensor, if it's giving a resistance to indicate that the engine is warmer than it actually is then the cold start fuel fuel settings will not be rich enough.

Hello Vinciebhoy,

That sensor looks good.
Ayway, if I kill the engine straight after starting, that doesn't change the coolant temp.
So second start then should also be troublesome, but that isn't.....

Thanks anyway

Greez,
Moh

Never liked the K&N and other clean, re-oil and re-use type air filters. Has it been regularly cleaned and re-oiled?

Hello Art,
Filter is clean and a little greasy.
However, I do plan to replace it with a paper one, in OE style.

But Art, as you do have the "Legend" batch,
Do you now what criteria the ECM checks before releasing fuel ??

Greez,
Moh
