It was giving two codes 11- ECU(+B) and 12- RPM signal (Cranking).
I have tried adjusting pump. But it doesnt help.
At times turbo kicks in and after some time rpm suddenly drops.

check dist wiring for a short between dist and ecu also check for wire leading to ecu from positive for same. check all fuses with a test light as well auto parts rent gauge but yo may need an adapter 33-37 psi regulated and 38-44 unregulated.
