My 500 1.2 Lounge will fire/start and then stop before starting and running ok on the second attempt. I’ve noticed that the engine “hunts” slightly when left idling.
Feels like a fuelling issue. Anybody point me towards where best to start looking to save me messing about? I’ve not so much as lifted the bonnet yet.
I might also occasionally get a slight whiff of fuel around starting. A small fuel leak would possibly make sense.

its a 1.2 fire Engine, same as you would find in a late panda (mk2), and a punto... stick it though fiat scan and see whats up. Im going to say vac leak, throttle body gasket, or temperature sensor.
To be fair, its a incredibly old engine, not a lot big goes wrong with them

The Grande punto and early 500's had a common fault where the cam cover breather hose would crack and cause a vacuum leak + petrol smell. The crappy plastic hose was later replace with a silicone version which you can now buy as a spare part from Fiat dealer (or ebay, eg. # 130454615134 ). Think this was only on the 1.1, 1.2 and 1.4 8v engines.
Easy enough to check (though you might have to remove the airbox as the hose runs below it) and replace, so worth checking that first.

I had a quick look (too cold) and I think I have a silicon hose there. Gave it a wiggle and it didn’t cause any engine note change. I’m not 100% sure, but turning the ignition on and waiting a few seconds (a la diesel glow plugs) seems to result in a reliable start. In any case, it always starts fine second time and always fires first time but fades.
