I just finished my B18C1 OBD2 swap into my 1988 crx si
I am not getting any spark
I am useing a OBD0 TO OBD1 harness from blown hatch for the ecu
I rewired my Dizzy like this... from the engine harness
Non-OBD sensor (EF)-> (EF)Non-OBD pin ->(EF) Non-OBD Wire color ->OBDII sensor ->OBDII pin ->OBDII Wire color
CYP G c2 blue/yel CYP M c14 white
CYP P c1 blue/grn CYP P c4 orn
CNK G b12 white(small) CKP M c12 blue/yel
CNK P b10 orn CKP P c2 blue/grn
TDC G c4 wh/blue TDC M c13 wh/blue
TDC P c3 orn/blue TDC P c3 orn/blue
non-OBD Blue goes to OBDIIblue (tach)

non-OBD Black/yellow goes to OBDII black/yellow

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

and no spark so did I wire something wrong?
I am useing an OBD2 dizzy
I am getting power to the coil but no spark at all
can someone point me in the right direction?
thanks

 

anyone?

 

I wired my civic to OBD1 using an OBD2 distributor.

All of the dizzy wire colors matched up except the two OBD0 white wires. I guessed on those two and must have got it right.

It appears that you maybe haven't matched up your ORANGE wire. Not sure though.

HTH

 

try switching the white wires first.

then mess with the orange wire.

 

tried everything even another coil, but no spark still.
any more ideas?
thanks

 

did you wire your map sensor right

 

check your grounds.

one going from the frame to the tranny and one from the frame to the valve cover.

 

I know where the grounds are I hooked them up

and I dont need to wire up my map sensor, I just used the one on the firewall and hooked it to vacume.

I have power to the coil but no pulse?
but I am getting an injector pulse.

I had a similar problem...... There is a third, most important ground, however. It bolts on to your thermostat housing.... IT is a key ground, because it grounds out like everything, motor, ecu... There are about 5-6 wires in that part of the harness...CHECK THAT. It is very easy to miss.

i'm glad i wasn't the only one who **** his pants when the new engine wouldn't start. yes, the ecu ground is very important. is your fuel pump coming on for a sec when you click the key on? if it isnt, then your ecu isn't getting power/ground. don't just narrow it down to the dizzy, assumption could be your problem here.

I am getting fuel and Ii do have power to the coil, but still no spark. I am going to try a new igniter tonight, a wire was hooked up wrong on the igniter when I took it apart, so I am hopeing that killed the igniter.
also i do have all the ecu grounds taken care of.
thanks

 

still no spark???
