i just recently rebuilt my d15b1 and did the dpfi-mpfi swap. Ive tried starting my car numerous times and the ecu keeps giving me code 4 only, im also not getting any spark. I didnt get code 4 till i bought a good working dizzy and gave it a new cap and rotor along with spark plugs and wires. Ive been messing with the timing but still cant get rid of code 4, any help is appreciated.

 

30 views and no input? im about 2 seconds away from selling this thing if i cant figure it out. ive searched up, down, left and right and cant find a straight answer

 

The distributor part of you mpfi conversion check the cps wires. blue/green and blue/yellow

 

check the coil fuse on the panel under the dash
