Hard starting wehn engine is hot.

Post by CHB »

guys i am running 2.883 MS2 V3 and all these while its being running great except hot starting.
i have no problems at all during cold cranking and the engine fired up within the first few rotation but things really not working well during hot cranking. it always need long cranking until sometimes i have to worry that it will drain all my battery power.. :shock: but normally it will finally started lazily after the long cranking.
i have tried to tweak every where possible in my megatune and it never improve the hot cranking. did i missed out something? can some one have a glance at my msq file?

When you start the hot engine is the key already turned on or not. ? By that I mean when you turned off the engine did you turn off the key all the way so the processor was off or just turned to accessory position ?

Second thing to look at: when you are hot starting and it's not catching and you do a datalog of it, does the rpm keep going to 0. (You don't even have to datalog - just look at the rpm gauge on the PC.Does the needle pop down to 0 for an instant every so often ?)

Third - did you try both enable and disable ASE on hot restart ?

Q1) Yes. Hot starting i mean is drove my car to grocery store, off the engine. After do some shopping, get back to car and start it to drive home after the hard starting procedure.

Q2) The Injectors LED always blinking when i trying to start the hot engine, which means the MS2 is catching the RPM even, but barely fire it up when hot.

Q3) Yes i did tried both enable and disable the ASE. nothing helps.
