I just swaped a B18C1 OBD2 into my 1988 crx si.
I am useing a obd0 to obd1 conv harness and a stock p28 ecu
I am also useing the stock crx injectors and the resistor box.
I rewired my distributor, and everything else was pretty much plug and play.

here is my problem, the car will crank but I am not getting a pluse from the injectors, but they do have power, I am also not getting any spark, but I do have power to the positive (+) side of the coil

can anyone give me any ideas on where to start troubleshooting.
I already checked the grounds the dizzy and the injectors. I am at a loss, I have done a few swaps before, but this one has me clueless

I dont have my alternator hooked up, could that have anything to do with it?
thanks

 

check the ground above the thermostat

 

Also check the main relay.

shoudlnt be the main relay, I am getting the fuel pump to kick o, and now I just tested the injectors, and it seems as though I am getting fuel. my plugs are wet, not much but a little, and the #1 plug seems to be getting more wet then the others.
so could it be something as simple as a bad rotor or distributor car, after all I am getting power to my coil, but I just wasnt getting any spark by testing through the sparkplug cables.
I am going to try new cap and rotor, and may be even wires, wish me luck.

also does anyone knwo if OPBD0 injectors with the resistor box will work with p28 ecu and a OBD2 distributor??
thanks

 

Maybe you wired the dizzy wrong and you are not getting the right signal to the ecu.

here is how I wired it let me knwo if its right?
thanks
I rewired my Dizzy like this... from the engine harness
Non-OBD Wire color -OBDII Wire color


blue/yel to white
blue/grn to orn
white(small) to blue/yel
orn to blue/grn
wh/blue to wh/blue
orn/blue to orn/blue
Blue goes to OBDIIblue (tach)
non-OBD Black/yellow goes to OBDII black/yellow

non-OBD (large) white goes to OBDII yellow/grn
