yaris hard starting when hot, fine when cold

[ianpog]

hi there. Anybody have an idea on this? i have a 2007 toyota yaris. I'm having a problem on hard starting specially when the engine is hot.

it goes like this: when it's early morning like 7am, it starts fine. When i shut it off, then immediately start it, it's fine either. BUT when i drive it for like a couple of minutes, then shut if down. leave it off for 30minutes to 1 hour, then it will be hard to start. Then comes next day early morning, it fires fine again. I notice that if it sits off for like 8 hours +, it will start nicely no problem. but when it's off for 30 mins, 1 hour or 2 hours, (like when i park it when i'm going to the mall), it will be hardstarting.

hard starting, i mean like 3-5 secs before it fires up. I smell some fuel at times. Went to toyota dealer and they diagnose it, they saw fuel injector problem. i went to some mechanic, cleaned the fuel injectors, still the same hardstarting. I already replace the spark plugs, air filter, and a new battery. Still the same problem

Anyone can please help me?
