whats good i just finshed doin the wiring to my car for the b16 swap with a obd 0 pr3 ecu, i ran the knock sensor and the o2 sensor and the 2 vtec wires but when i started the car it runs fine but the check engine lights on and the ecu is reading 4 crank sensor which is in the dizzy but theres nothin wrong with the dizzy please someone help me out:rimshot:
 
What OBD is the distributor? What engine harness mods did you do?
 
i have the stock jdm obd0 b16 dizzy and i just bought a new ls dizzy stock si harness i wired knock sensor ,vtec,vtec pressure,2nd o2 sensor everything came out perfect its just the dizzy with this crank sensor issue car starts and runs fine just hesitates a little when you press on the gas pedal softly
 
I may be wrong but I do not think you can use a LS dizzy on a B16.....

Second O2? OBD2A ECU/motor???
 
You can CAFROG its just that the bolt holes don't line up... and second yeah obd2 in a obd0 car.. why would you wire up a 2nd o2 and knock sensor..
 
um i wired the 2nd o2 sensor and knock sensor cause i have a obd0 pr3 GSR B17vtec ECU
 
Didn't know that there was an OBD0 ECU that needed two O2 sensors.

It hesitates with both distributors? (you spoke of a OBD0 B16 and OBD0 LS)

What is the Electrical timing right now?

Did you change the timing belt and maybe the mechanical timing is off a tooth?

Any CEL codes?
 
um i wired the 2nd o2 sensor and knock sensor cause i have a obd0 pr3 GSR B17vtec ECU

GSR b17 ecu is a p61 and it's obd1
pr3 is a JDM b16 obd0
unless it's a pr3-j00 or the pr3-j51which came from the JDM integra xsi with a b16 and it's obd1 also. Check for the -j00 or -j51 after the pr3. If you have one of thoses ECU's then you will need an obd1 dizzy, or find the obd0 pr3 ecu. I hope this helped.
 
get a multi-meter.
find the correct wire for the crank sensor.
test it.

either you need a new dizzy, or theres something not hooked up/grounded correctly.
