96 Prelude SI OBD1 JDM H22 Help PLZ!!!!
Alright helpin my cousin swap a OBD1 h22 into his 96 prelude si h23. I reused the h23 harness, wired up vtec, re-used the obd2 h23 distributor.
Tried to crank the car no spark.
I know obd2 has that crank position sensor i didnt swap the oil pump over so it not plugged in.
I read online that i can rewire this crank sensor plug to the Obd1 jdm dizzy. how do i go about that.
ANY HELP WILL BE GREATLY APPRECIATED...reps also
that will work for the prelude??
That is just for the civics and integras. The Preludes and Accords don't have the CKF(crank fluctuation sensor). The H23 dizzy you have has a 4 wire plug and a 2 wire plug correct? That means that only one of the three sensors needed (CYP, TDC, CKP) are in the dizzy. The other two are on the oil pump and use the timing belt gear and balance shaft pully to read from. The JDM H22 dizzy has a 8 wire plug and a 2 wire plug. This is because all three sensors are in the dizzy. You will need to run the wires in the engine harness that normally plug in down by the oil pump over to the dizzy and use the JDM H22. You will also be changing from a external coil to an internal coil.

alright i think it goes like this havent had to look at all the diagrams but im sure im close to being 100% right just unsure of 1 thing the JDM dizzy only had 7 wires.
heres how i think it goes...any body i need help
yellow/green to yellow/green
blue/green to blue
orange/blue to idk what green wire its suppose to connect to...the one from the crank sensor or from the obd2 distributor plug?
orange to yellow
white to black
white/blue to red
blue/yellow to white
besides the orange/blue to green i think i got it right...i just dont know if the orange/blue connects to the obd2 distributor plugs or the crank sensor plug.
either way i will have a left over green wire....
HELP anyone?
alright re-wired cranks but still doesnt start...
did you jump the ext coil plug? so it will fire.. green wire runs to it as a signal wire.
The EMPIRE
how do i do that?
There is a square plug w/ 3 wires, jump the two fat wires (connect them together)
The EMPIRE
starts but is runnin funky...lots of smoke
bring it by.
The EMPIRE
it runs good my cousins header is just cracked...thanks for all the help everybody!
one last thing should i be using the obd1 h22 injectors or the obd2 h23 injectors?
h22 injectors the h23 has a differ flow rate and the h22 is better
thanks that is all
alright one last problem!!! car is overheating and heat isnt working. fan wont kick on. Ive slimmed it down to a couple problems.
1. thermostat
2. the h23 had a sensor on the top radiator hose connection gunna put that on the h22
3. switch out radiator and fan
4. flush cooling system
5. waterpump
