wild guess, was your fuel pump priming when key ON ?Since last time is like that hahaha. Even after full overhaul last year also like that lol. Suspect is nozzle clogged or leaking (where to do nozzle ultrasonic In penang?)

can hear it prime for 1-2 seconds then quiet. Tried after prime immediately turn, after prime 20 seconds only turn, no wait prime immediately turn, all can start the car. Also all same result, the car will die immediately afterwards. Very rarely it will stumble till almost 0 rpm then somehow manage to go back up the rpm and idle.wild guess, was your fuel pump priming when key ON ?
I still think this is something to do with the coolant temp sensor and your ECU. Cuz warmed up the car no issue - I suspect the cold start management of the ECU is not working properly somehow.can hear it prime for 1-2 seconds then quiet.

Comes to think about it, it might be the coolent temp not detected by the ecu. When started in cold, the idle is at 950 rpm. Supposed to be higher i think. After warm up, it will go down to 850.I still think this is something to do with the coolant temp sensor and your ECU.

I don't think you can with stock ECU unless you have some sort of diagnostic tool. And you're right, cold idle is usually higher.Comes to think about it, it might be the coolent temp not detected by the ecu. When started in cold, the idle is at 950 rpm.

How do i check whether the ecu is detecting or the coolant temp is not faulty?
Yup it was changed. Also there are change in the temperature meter when car warms up. Im thinking...maybe i should clean the throttle body first. Will spray one can of throttle body cleaner into it tonight.I don't think you can with stock ECU unless you have some sort of diagnostic tool. And you're right, cold idle is usually higher.
You mentioned you changed your coolant temp sensor recently right?
If its not reading accurately then no error code will pop up. Error code will only pop up when the reading is out of spec.Comes to think about it, it might be the coolent temp not detected by the ecu. When started in cold, the idle is at 950 rpm.

Perhaps your piggy back has some settings off, what sort of piggy back is that ?I think i cannot reset my ecu. Its already got a piggyback.. later reset d all my settings run away
Im using emanage blue. I took my car for dyno tuning last year and asked the tuning, he said its not due to the piggyback.Perhaps your piggy back has some settings off, what sort of piggy back is that ?
Like many experienced car guys in ZTH said, Emanage is also known as EDamage, i am not sure how old was your ECU but do get second opinion.Im using emanage blue. I took my car for dyno tuning last year and asked the tuning, he said its not due to the piggyback.
Could this be related to a bad crank angle sensor?My car if shutoff for too long it will have this one small issue. Basically after shutoff for >8 hours, on first start up it will always die immediately if i didnt press the gas a bit. To prevent this everytime after shutoff for more than 8 hours, when i turn the key need to give it a bit of gas then only ok.
Thanks

Are you running any custom sensors? can the EManage be bypassed?Like many experienced car guys in ZTH said, Emanage is also known as EDamage, i am not sure how old was your ECU but do get second opinion.
Why is it EDamage ya? I do not know the stories regarding this..Like many experienced car guys in ZTH said, Emanage is also known as EDamage, i am not sure how old was your ECU but do get second opinion.
No custom sensors. Perhaps some tuners here can commend on this?Could this be related to a bad crank angle sensor?
I dont think so..bad crank angle sensor will cause issues everytime during startup.

Edamage stories i'd heard that it will fry your stock ECU, other cases like the stock ECU will revert to stock settings while ignoring Emanage.Why is it EDamage ya? I do not know the stories regarding this..
