So as the title says I did a b swap in my 89 CRX and ever since I got it to start it's always been in limp mode and whenever I look at the ECU it blinks 4 times followed by one blank but the one blinks is the oxygen sensor which isn't really a big deal but the one that's been troubling for me was the four code or the crank position sensor and I tried messing with the wires on the distributor and there's been no progress so I was wondering has anybody ever encountered this problem and if you did what did you do to fix it because it's annoying being in limp mode also it blinks 8 times also causing it to be in limp mide and I cant figure out what the problem is

 

Was it working before the swap without being in limp mode? If so, what did you change wiring-wise? Double check/trace the wires from the distributor to the ECU and compare against the wiring diagrams in the HELM manual. If you ran new wires, were they shielded wires? Did you ground the shielding on only one end?

 

it wasnt running because the dizzy was bad so I boughht one off amazone and put it on and the car runs but its in limp kise for code 4 and code 8 went away. Also could u explain more about what u mean about grounding the shielding wires im new to the engine swaps lol

 

What B series and OBD0, OBD1, or OBD2?
What vehicle did you buy the distributor for?

 

its a B18b1 running a pr4 ecu meaning that its obd0
and I bought the dizzy for a 96 integra being thats what the engine came out of

 

There's your problem. If ECU is OBD0, distributor must also be OBD0. If ECU is OBD1, distributor must be either OBD1 or OBD2.

 

so should i have gotten a dizzy for a b18a1 because isn't that one obd0

 

Correct.

 

thank you
