Aoa,
Guys my cuore is not starting in morning only.It needs a little push approx. of 10 feet and then it starts and works like a charm all day and night without a hassle.
Generator and battery has been changed recently.Self is working fine.Fuel pump is checked and it is working fine.There is no missing or loss of power during driving.
Give some advice regarding the starting problem only in morning.
Thank you.

Is your car cng ? Is the starting problem on cng or petrol ? I had coure. Same problem was there. But it had starting problem on petrol only. And it was solved by changing the carborater due to malfunctioning of auto choke.

It could be because of leaky valve,first of all get the tappets adjusted.

Try starting the car without pressing the accelerator peddle.if it automatically accelerates on cold startup then the auto choke is working if not then there is a problem with it. Rest wait for the experts reply they will guide you better.

Even if I turn off the engine after starting in morning by a little push and start it again by using the key it starts in a half self and it seems that there was no problem at the first place although i feel the race is not adequate enough to keep the cold engine smooth as i feel little vibrations but engine does not stall even if I take off my foot of the accelerator pedal.

if you and your mechanic cannot figure out then i think the best way is to visit Toyota company workshop
they can diagnose the issue.

Aoa,

Mere cuore 2006 model car ko jab main subha CNG par start karta ho tou wo race chorne se band
hoti hai or vibrate hoti hai bht zyada approx 5 mint tak race deni parti hai pir thek hojati hai mechanic
k pass le kar gya tou os ney spark plug air filter or point new laga diya lekin problem still hai kindly
suggest the problem?

The CNG air/fuel mixture is too lean - i.e. engine mein dakhil hoti hui CNG ka pressure kam hai.

Get the pressure increased slightly - this will lead to a reduced mileage, but the engine will receive the proper amount of CNG, and it will idle at cold start properly.

Mechanics usually set the mixture too lean to increase mileage - this leads to rough cold idle, and the engine may overheat during normal or spirited driving.

My car has the same problem. What was the solution to your peoblem?

I have had 2003 coure cx since 2016. It is a running vibrator. I was facing the same issue. I removed CNG right after when I bought it. I though the problem would be solved, but no! It kept jerking and vibrating. Finally, I converted to CDI and changed the battery. Also, get the suspension work done and installed Bridgestone tires. Since then, it has been smooth. Since the current has increased, there is no lagging or starting problem in the morning.
