Engine start up/ cranking time

Hello all,

Wanted to get some thoughts on the following:

When I start my car 04 F1 Modena - I notice that it cranks for about 2-3 seconds (max) before the engine comes to life (what an awesome Tubi sound!). I was curious if this "delay" is normal or if it is truly a delay. This is a cold start after the car has not ben driven for > 48 hrs.
The "delay" is decreased to 1-2 seconds if I was to drive the car and then later that same day start it up.

I do not think this is any different then when I first got the car approx 6 months ago, but now as I drvie it more - I am paying more attention and getting more familiar with the car.

On the same note, I was thinking if I need to get the fuel injectors cleaned, is this recommeded. Anyone have recommendations on fuel injector cleaners/ additives that are "safe" to be used in fcars.

Appreciate your inputs - thanks!

Pat, that's what it usually takes also on my 430 when cold starting the car. Between 2-3 secs. I consider it being normal as any car that sits several days would take approx the same time to come to life.

I believe Terry advices Techron additives for cleaning the injections which is widely available in the US but not in Europe

Mine's the same. The motor does not even try to fire for 2-3 seconds. I'd assumed it goes through a cycle and only fires the injectors a couple of seconds into it.

After short-cycling it too many times on startup, I can say the same.

Stablemates: 06 F430, 95 M3 Track, 08 M3 Vert, 04 Cooper S, 08 M5 - All with 3 pedals, of course.

Must be a V8 thing. My V12 fires instantly.

I always thought that this is good for oil circulation when the engine is stone cold.

Hakan- The oil flows when she is running, too. On new engines, it is recommended to ground the ignition and turn the car over a few times to make sure there is oil everywhere with no load, but not a problem with engines that are used regularly.

Taz, I always feel uncomfortable with my car as it is jumping to 1500-1700 rpms when i turn the ignition on especially when it is cold. This is the reason for me being on the side of 3-5 seconds of cranking time before turning it on completely. Well ,maybe this is just psychological or old fashioned but this makes me feel better.
And I also believe that only way of destroying a well maintained Fcar engine is leaving it either without oil or water.

I would say my 360 takes about a second and a half to start, but never more than two seconds hot or cold. That's about how long it takes to start my Ducati motorcycle. The delay is not long enough to be a worry, but it is defiantly longer than my Fiat.

Hakan- 1500-1700 rpm for cold start is no big deal. Needed to keep the light flywheel engine running when she first lights off, and with little load, not hurting anything. Some of the early smog Ferraris thundered up to 3000 rpm on cold starts, and that is a bit excessive. Your car idles around 1000 rpm, so not that far above idle. The 575M cold start is 1400-1500 rpm, but then they idle at 800 rpm.

Thank you for all the input!

It seems that this "delay" is fairly common in the 360/430 cars per the posts (that's good to know)
I was curious since all cars that I have driven that did not instantly start up there was a concern about the battery/solenoid/starter motor/injectors.

I have a fairly new battery in the car so my concern was about the starter motor going bad, but with the above post gives me a bit peace of mind. Nonetheless, I will observe if the "delay' duration increases.
The max delay I believe was 3 seconds, but I will actually use a stop watch and time it

Thanks again for the posts and info. If anyone has the same as above would like to know (or different than above)

UPDATE:
I timed the "delay". Car was started after 5 days. Ambient temp 70 degrees. The cranking time took exactly 2 secs before the engine fired.
