Hey guys, I'm new to the forums and this is my first post. I have a 96 Accord project currently underway, the motor is a freshly built f22b1 block mated to a f22a4 head. I just installed the motor and the wiring harness, and when I went to crank the motor, there was no spark. So I asked some friends of mine, and came up with some information. The f22b1 block is OBD1, while the harness is OBD2. This presents an issue because the block is not provisioned for the crank position sensor plug on the OBD2 harness. So in turn, my distributor is not recieving the timing signal and therefore the coil is not sending any spark to the dizzy. I have the TEC external coil dizzy that came stock on the F22B2. So my question is, what are my options to fix this issue? I was told that I could use an internal coil distributor and wire the crank position sensor into the new internal coil distributor. This engine has an ATI Superdamper installed, so installing the sensor that goes to the oil pump housing is out of the question. Any help would be very much appreciated. I have searched and can not find anyone experiencing this problem.

 

it probably would have been easier to start with an obd2 block but....
you will need a dist with that sensor in it. then hardwire in. I would also use the int coil dist like you said.

 

You may find that you will need to wire up both the TDC and CKP sensors from your new distributor. Make sure the distributor that you buy is OBD1, as both OBD2 internal or external coil distributors only have the CYP sensor in them. The OBD1 distributor has all three sensors in it, TDC, CKP & CYP. wire them up to your OBD2 wire harness and you should be good to go! you will have to get creative on the connector as the OBD1 and OBD2 don't match up. if you are familiar with removing the wires from the connectors you should have no problems switching them over. Ether that or you can cut he wires and solder them... To each his own!

 

In retrospect, using an OBD2 block would have avoided this whole headache. Will keep that in mind for future builds, thanks for your help.

 

I retrofitted my distributor with the sensors from an old obd1 my buddy had lying around looking for a low cost solution. I ran the wires from those sensors out to their corresponding locations on the crank position/tdc plug from my old block and am going connect it to its plug on the harness and see if it gets spark. If not, I will move to buying the obd1 dizzy. I appreciate all the advice. Thanks

 

On second thought, I'm not 100% sure about the modifications we did to the distributor but its just a theory, and it was free, so I will test it. If not, onto the H23 dizzy.

 

You have to make sure that if you move the VR sensors and magnets from one distributor to another that they are lined up perfectly or the timing will be out of synch.

 

The b2 and the b1 share the same oil pump and sensor assembly and crank timing and balance shaft gears. Assuming you rebuilt your existing b1 motor(since you don't clearly say what motor you originally had), you just need to use your existing oil pump assembly to the newly built motor or source another oil pump and sensor assembly and crank timing and balance shaft gears(any 96 accord pump since 94-95 won't work).

If you contact rywire they might be able to make you a conversion distributor subharness to plug into your existing distributor plugs to convert from external to internal then just source an obd2 b1 distributor(96 accord ex).
