Hi , I have same thing on my 2004 3D , what is wrong with this engines?"?????

I rebuild engine with new all new parts and change MPEM and ECU .I try put new sparks, ing. Coil all things. Nothing.
Is shooting into the intake. When drop on water go maybe 15mph or less.
Also my lights on guide are on all time when engine is running. I don't know why.

, I'm thinking that ingincton timing on MPEM need to be reprogramed . Because of new marks and points on new parts. After rebuild all marks and points are in different positions , that why is shooting ( to intake or to exhaust ). I'm right?????????
