I had this same problem in my car but not that when it's hot it shows this annoying symptoms, mine occurred when hot and cold. My brother in law said it was the kick starter so to test it truly and confirm I take a metal rod and hit the kick starter on the body, this worked for 2 days on the 3rd day, nah him I nack nack the thing no work.

To confirm if truly it's the kick starter, you need a rewire to help he will you wire one kind to connect the thing but if the car stalls on the way you need him to do it again. Just fix it around 6k 1 and half years ago don't know how much now.
Please stop depressing the acceleration while cranking the engine not good for the car good luck

Thanks Nurey. I changed my kickstarter 3 days ago. And the situation hasn't improved. Kick starter was taken from tokunbo engine. Thanks.

It may be a faulty fuel pump,i once experienced it in my camry 2004

boldx:
My car is 2000 sienna. 3.0 Litre V6 engine.
The engine cranks well when cold and comes alive but does not start easily when Engine is HOT unless i throttle a little. I have scanned and there are no codes at all.
The car runs extremely well, doesn't drag at all when climbing a steep slope. No rough idling at all.
On live data, STFT is -3.8, LTFT is 0.0 for bank 1 and 2. Timing advance is 15-17 degrees.
The thermostat is still very much in the car and it doesn't overheat. Normal optimum temperature is 91*C. I don't think its a fuel pump issue.
Am thinking of ECT sensor from my online research. Please help. This is complicated for me.
Many thanks in advance.

Scan your car and come with teh codes,
U have same problem with my Jeep liberty, it turns out it was the Cam positioning Sensor, but still scan for fault codes

nurey:


I wanted to suggest this too but don't have much info on it. Am guessing the engine should throw a code if it's cam sensor and you said no code. Also since it is only hard starting when hot you are experiencing I doubt it's the cam/crank sensor.

boldx:
I sincerely appreciate your concern. I will find a way of showing appreciation as time goes on.
My camshaft sensor on bank 2 of my V6, the one close to my radiation has a bad clip. Though it is still fitted, you can pull it off without any resistance.

erico2k2:

Take a pic lets see as you are me ant to have one cam sensor and you screw it in, its not a clip mechanism.
