Doing a job for a customer: 1992 prelude with h23 swap. He threw a rod and wanted a h22a swap put in it. Got the long block and put it all in. Using the h23 harness and Trans. My questions are map sensor? Use one on fire wall or tb? No spark at all. I am running the h23 dizzy and external coil. No spark. I just need guidance and help. It's frustrating me badly. Please help guys. I just want it running and out my yard so I can get paid lol

 

It probably had MAP on firewall, so I would use that.

Are the grounds good, specifically tranny and the one by the VTEC solenoid?

 

Ok on the map and the grounds are great. So lost

 

Agreed, I did the exact same swap in my 92. I ran vtec solenoid and pressure switch wires to p13 ECU, H23 TB and map sensor (tps sensor broken on my h22). Started up right away.

As far as your no spark... Are you sure it's an h22a and not an a4? The a4 has the crank sensor on the crank timing gear instead of in the dizzy like the h23...

 

It's a 95 h22a. No crank sensor by pulley. How did u run the external coil

 

The 92 h23 harness has the plug for the external coil already there. I used the jdm, dizzy on my swap so i had to jump the connector to provide power to the internal coil. I would have used the h23 dizzy with external coil had it not been throwing a code before I did the swap.
Have you checked your ecu/radio fuse and ground?

 

Where is the ecu/radio fuse and ground? The radio works....

 

Under hood fuse panel. What ecu are you running?

 

Fuse and p13 and I tried the p14 and still nothing. Would the ecu stop it from spark

 

See if you have crank an cam sensor signal going to the ecu. And double check your dizzy connections.

 

Also check the icm output to the coil.

 

You did not specify if this was a H23vtec Bluetop or just an H23a/a1 nonvtec motor.

 

H23 non vtec

 

Bump

 

Is everything I suggested checking good?

 

How do I test the coil

 

Back probe the thin blue wire at the coil connector and use a test light while cranking.

 

Do u have a number I can call u

 

and you are a mechanic professionally or a shadetree mechanic?

 

I have a degree in automotive tech and yes I didn't know how to test the coil. Are u here to help me figure this problem out or judge me?!?

 

Did you test the coil?

 

Yes good

 

Is it getting the trigger signal on the thin blur wire or did you just ohm it out?

 

Ohm it out

 

Test to see if it is getting the trigger signal on the blue wire at the coil connector. If not your problem is ecu, dizzy, or wiring harness. If it is getting the trigger signal the your problem is cap rotor wires plugs or coil.
