Default MPFI PROBLEM HELP PLEASE

Okay I have a 89 CRX dx I converted to multi point using the hasport and rywire diagrams. I used a z6 mainfold and obd1 injectors and deleted my resistior box with the obd2 plug and im runin a DA ecu. everything is pined corectly ive checked idk how many times. all the conections are good as well.

But heres the problem we got it running but in safe mode well i had to be to work so I drove it in safe mode well i got about two miles and it started to back fire and mis then it just bogged completely down and it wouldn't start. I found out that the timing belt tensioner went bad replaced it and put a new timing belt on and it still wont start. its gettin spark and the injectors are firing in the correct order and timing is dead on i pulled the spark plug out of number 1 stuck a long screw driver down it to find top dead center and confermied it with the timing marks. It still sounds like its out of timing and it will crank and back fire run for a second and die im so lost for what to do next the only code i am throwing is one long blink thenfor short ones and like i siad im runin a ls ecu on my d15b2 i know the 4 blinks mean cps but its a brand new dizzy and i have checked all of my conections over and over i am so lost im about to crush the damn car

PLEASE HELP ME

well.. it's either bad wireing, timing, or something stupidly simple. check the dizzy again make sure all the wires are hooked up properly, make sure all the wires are properly ran at the ecu plugs, make sure the timing is correct if it doesnt crank up.. i dont know.. it could be the dizzy new or not it could still be bad.

so my idiot friend who put the dizzy together didnt put the screw in the rotor found that out when i took it a part. so the car runs now but its back in safe mode AGAIN it will sometimes rev to 4gs if i stomp on it but if i ease on to it it revs to 3200 and im still throwin a code for cps it pisses me off i just rewired the whole car Again with brand new wire just to make sure there is no break ups in the wiring any ideas why i am in safe mode the car is wired correctly im stumped other wise

its either mis wired (check the 2 white wires, try swaping them around) or its the sensor in the dizzy. its become more common to get defective brand new parts.

um.... if all u did was change the dizzy and got more codes, then either u have some wiring issues or that ecu is throwing ghost codes. its probably the ecu if ur certain the wiring is good and uve now tried 2 different dizzys. do u still have the other dizzy? if so what happens if u put that one back in?
