Status: offline 		My 2005 42000GT has had this problem for a few years - wondered if anyone else experiences it?

Car starts well when cold and starts reliably when warm - sometimes a little splutter but always first time. However, after refuelling the car it takes 3/4 goes to coax it to life (and "Ah, a dodgy maserati!" schadenfreude looks from those filling up nearby..) - including copious prodding on the loud pedal! I usuallly fill up within 10/20 miles of the light coming on and always use V-Power (occasionally other high octane). The problem is most severe if I fill the tank to full; my workaround is to just put 50l in - in which case it usually starts second time no problem!

Main dealer just tells me "it's fine!"....

My Triumph Stag can be sometimes awkward on a hot start, but that's down to fuel vaporisation in the carburettor, not being fuel injected. Strange.... Cheers Mike

Status: offline 		I don't recommend 'prodding the loud pedal' when trying to start it. You are probably confusing the dim-witted ECU. My old Beemer had a note in the handbook warning against touching the accelerator until the engine had actually started. I've not seen anything in the Maserati manual about this but the manual is a bit sparse.

Mine starts on the button everytime although it can occasionally smoke a bit if it is restarted without being previously warmed up before turning off. The dealer says it is completely normal and due to the drop-forged pistons not filling the bore until the engine is warm.

I've also heard of some having a problem with the fuel tank not venting properly. When the tank is completely filled, the vacuum is strongest if the venting is faulty and it can stop the pump from making full pressure.

Hope you get the problem sorted quickly.

Status: offline 		I can't offer any useful feedback on the starting issue/fuel tank status here, however, I am interested in Doodlebugs observation regarding smoking.

My car starts first turn into a roar of excitment which wakes up all those nearby! I love it!

However, on occasion I too get the blueish smoke. This upsets me. It happens usually after I restart the engine after a short run (<15mins). But not always. However, it has also happened after a short stop (~2hrs) after a long run (~3hrs).

I would welcome someone on this forum explaining to me what is actually happening here - as I said, it upsets me.

many thanks Dave

From what I understand and I may be completely wrong, the engine has drop-forged pistons which don't fit in the bore as well as the usual cast jobbies until the engine has warmed up. If the engine is used for a short period of time there is quite a bit of oil left on the bore walls because the oil rings haven't had a chance to do their job. When the engine is started again, this oil burns off generating a bit of bluish smoke.

One thing is for sure. The smell of burning synthetic isn't a patch on GTX.

Interesting thought on the venting - can't say I have noticed but will listen carefully next time I re-fuel which is never too far away!

I suspect this is your problem, sounds like there is a straightforward fix http://www.sportsmaserati.co.uk/showthread.php/4146-Poor-starting-especially-when-hot-even-worse-when-filled-with-fuel?highlight=vapour Simon

Try starting it with the filler cap off just as a test.
I don't think there are any sensors to prevent this.

Status: offline 		I have had a one off (so far) problem with changing gears on my 2006 4200 Coupe CC. The selected gear change did not happen despite showing a gear change on the dash display. It seemed like an electronic/computer problem? It righted itself after 5/10 mins. and seemed to perform perfectly from then on. Any suggestions? kevla

Status: offline 		I've had something similar though not as severe as yours by the sound of it. last few times I've filled up the car after a decent run the car has started fine but then driving away there as just a slight faltering in the engine, as if the fuel is struggling to get through. I wondered whether it might be some muck from the bottom of the tank or even a suspect batch of fuel, but the vacuum suggestion might be a reason. though I can't work out why it clears after a couple of miles and only directly after filling up???!

Had exactly the same problem with my Gransport which Giallo near Sevenoaks fixed in 1/2 hour for £80
Speak to Matt on 01732 835692, it is a small valve in the inlet manifold which registers vacuum.
Mine was impossible to start after a fill up and when hot
Totally sorted now

Status: offline 		pgbj,

I have exactly the same problem, it started some months ago when I noticed a very slight misfire at about 2,200 revs. I spent hours trying to diagnose but had very little to go on as there were no recorded fault codes. I began to dread the need to quench the cars thirst for petrol, knowing damn well I would have to wait around fifteen to twenty minutes before  entertaining even turning the key. Holding the key over for a quite lengthy period will result in a very spluttery start at very low revs until the revs eventually pick up (the words To**er were being imagined leaving all spectators lips, especially after holding up the petrol queue!).
Now a fault code has developed showing the need for a flushvalve for the antievap system, it should arrive in the next couple of days, I will let you know if it is successful.

Here's hoping!
