Default Dpfi to MPFI Q's

okay i know this is an old and boring subject for some of you i just need a few questions answered, i followed all the instructions i could exactly, and for some reason, every time i turn the key to the on position, my check engine light flickers on really fast and my injectors are pulsing, wires A3 and A7 are going to injectors, and the solid red and yellow from my old injectors are going to the other two injectors, and then C1 and C2 are going to the dizzy, and all red and black wires from injectors are going to the resistor box, and the two yellow and black wires are going to the corresponding black and yellow wire from the resistor box as well. i am pretty sure i have the wiring correct, but iam using a PR4 ecu, from a 90 integra RS, and i am putting in a b18a1 from the same vehicle i see that alot of people use pm6, and other OBD0 MPFI ecu's but not alot of PR4s is the PR4 ecu my problem, or do i need to just look at my wiring bettter, oh yeah and i also swapped the wires around on the tps sensor too.... any help will be much appreciated.
all this is being done to a 89 civic hatch DX

double check your main relay, or hardwire all your injectors from ECU to INJECTORS.

just go over the wiring . make sure your resistor box is good. get under the dash and check the plugs over and over. try a friends pm6. if you live in austin tx ill give you mine.
