Mp9 Fuel Injection - Doesn't want to idle

[Lacizro.La.Camshaft]

Good day Guys

I have a mp9 system,when i switch it on,i can gear the throttle body calibrate/switching on but when i crank the motor,i have to feather the throttle to keep it alive,as soon is take my foot of,it dies.
I even reset the timing to make sure and the timing is 100%,fuel pump works very well,throttle body is well,i even installed a new distributor for control,after installing the new distributor,it was idling well for about an hour and went back to square one.
It is bored to 2.0L,the crank was worked on at engineering and the top was schemed.

I can't think what could be wrong?


Advise would be much appreciated!
