If my CKF sensor does not work will this prevent the car from starting?

Thanks I really need to figure out why my injectors are not firing although I am getting spark.

 

Basically this is why I am asking:

D to B Swap on 98 civic hatchy

Base model hatchy with y7 pre-cat from fact

B16 was a bit of a hybrid unit
OBD2 bottom end
OBD1 head
Used a Y8 Harness from an EL (canadian civic sedan sold under acura)
Using an obd2 del sol ECU for a factory B16 - P30 unit

Problem - fuel injectors do NOTHING. No ground pulsing from ECU

Continuity from injectors to ECU plug. Checked - A-OK
Fuel Pressure was A-OK
Pulsed injectors manually- A-OK

Wondering if ECU was buggerd so I used an OBD2 to 1 harness and then an OBD1 P30 del sol ecu that I KNOW works. still same issue.

SO, what does the ECU look at to trigger the injectors, the crank sensor or something else?

The bottom end of the B16 is obd2 and has a crank pos sensor on the oil pump that is plugged into the harness.

I am using a xenocron dizzy conversion harness to use an obd1 dizzy.

Where do I go from here. I am a little stumped here and I need this thing running so I can go home!!!!

Thanks in advance.

 

OBD1 ECUs don't look for a CKF sensor, so by trying that you've ruled out the CKF sensor (IIRC OBD2 ECUs will still run the engine without a CKF sensor, but it will run like crap)

Check to make sure the thermostat ground is connected and tight and clean. Make sure the ACG fuse under the dash is good.

 

The ECU uses the 3 sensors inside the distributor to coordinate fueling and timing efforts. The CKF sensor was introduced for OBD2 misfire detection and will not keep your car from starting.

Since it's a swap, making sure all the grounds (especially the thermo, like 94EG8 said) are clean and tight, is a good starting point.
