Hi, Andrew (Lang Racing) is one of my customers, he's a BMW expert.
He has done many LS Conversions.

I make coils, EMS, etc.
I would like to be of help, need more information OR call Andrew.

My guess = VATS

Lance

 

Thanks for reply bro
i was thinking about vatf r uh sure that ls3 have vats if it has what should i do know to disable it completely.

 

A VATS problem generally presents as a brief fire and quick shut off.

Check your grounds. Got the two grounds going to the back of each head?

Andrew

 

Then i think it doesn't have any vats problem because
there is no fire at all in coils and no signal from crank sensor also. And yeah i got both grounds tomorrow i will upload pictures of wirimg and grounds etc. and thanks for reply

 

Do you hear the fuel pump priming?

Andrew

 

Yeah i did here fuel pump sound even i connected lamp to fuel pump when i was cranking it was getting on well my guess is there is problem related to pcm or pcm itself because pcm is not giving any signal to coils or crank sensor.
