Title: Slow start/long crank.
Post by: Bellasdad on August 17, 2019, 02:53:22 PM
Does anyone have any issues with this?
It’s happened to me a couple of times now, gone to start the car and the engine turns over for about 5 seconds before actually firing up. Most of the time it starts immediately as soon as the key is turned.
Is this a characteristic of the Jazz or is it a trip back to the dealership?

Try turning the ignition on for a few seconds before trying to start. This allows the fuel to pressurise and the immobiliser to receive the necessary signals. If, after trying that, it still takes a few cranks to start, then speak to your dealer/workshop.

Yes mine has done exactly the same on a couple of occasions never fails to start but sometimes it cranks for longer than it should. My previous manual mk3 did the same. As they were both ex’s they have a start button so the engine start is computer controlled

Do you mean that pressing the Start button turns on the ignition?

Yes but opening the door with key in pocket might trigger something to wake up when you press the brake the button lights up but until you press the button it seems as though the ignition is off

Too technical for me. It took me all my time to get past turning the key then pulling the started knob on the dashboard!

Start on my motorbike is 'one touch' - you just blip the start button and the engine turns over and as soon as it fires it disengages the starter motor,  there is a limit on the time it will turn over for if it does not start though,  about 3 seconds I have been told.

Thinking about it all new jazz’s have the ability to auto start the engine otherwise idle stop wouldn’t work

It seems to be a characteristic more than a fault then.
I probably over exaggerated my estimation of 5 seconds before firing up, but it’s definitely not an instant start that I get 99% of the time.
I’ll keep an eye on it but if more people say they are experiencing the same issue then I guess it’s not a serious problem.

yeah i had a few times in the past and a long one today

fast turnover and eventually starts 3 to 4 seconds by itself i even took my had off the key

drove a bit and switched it on and off and its normal again

ive done 4000 in my car now and it has done it about 6 times

maybe i should try the turn the ignition on the first click and wait technique as i think i went straight to start today

Personally I have always waited until the petrol gauge has stopped moving before I try to start the engine...the short delay gives ECU time to get all the sensor inputs and fuel pump time to build up pressure.

I’ve called into the dealership and had a word with one of the technicians regarding this issue. He explained it was perfectly normal, saying the ECU would be going through it’s startup checks and the engine wouldn’t fire until certain parameters were met. He also advised to turn the key to the first position and allow any warning lights to go out before cranking the engine.
Following advice given on this forum, that’s what I’ve been doing for the past couple of days anyway and everything seems fine.
He also said if it becomes more of a regular issue to take the car back in and he’ll get it in the workshop for more investigation but he doubted there would be any further problems.

I have always done this and has never been a problem since I got the car 15months ago.

That’s got me wondering how you would do this with the start button as there is no key to turn to first position? As I said before mine sometimes cranks longer than it should but so far has not failed to start

Push the button without pressing the brake pedal. When ready to start press brake pedal and push button again.

A quick update on this topic for which others might find useful.
Just had my first service today and mentioned the starting issues when I booked the car in.
Apparently Honda are aware of the long crank issue and there is a software update now available to rectify this problem.
The  technician has assured me this will solve the issue and the car should start immediately at the first turn of the key.
I'm now going to have to get out of the habit of allowing all the warning lights to go out before starting the car.  ???

Same here.  After first service the long crank issue is gone

This isn't a bad starting technique to use all the time anyway as it allows the fuel pressure in the fuel rail that feeds the injectors to build up, particularly after a lengthy stop.

I agree completely but the service technician asked me not to use this starting method as he wants me to test the new software update to see if it is effective.
Like I say, it’s a hard habit to break but in the interests of science, I’ll give it a go.

+1

Also allows time for all the various sensors ( there are many on modern cars ) to stabilise and report in to the ECU.

+1, yes my bikes do the same,I think honda bikes are better than the cars.
