I have a 2000 Honda Civic Dx. I just built an LS/VTEC (99 CTR head, 81.5mm bore ls block with Mahle 9:1 cr pistons and eagle rods.

I ended up using the stock Y7 harness. I have an obd2b to obd1 jumper harness to a chipped P28. I am using a phearable basemap to run the car until I go to get tuned.


Following this https://honda-tech.com/forums/hybrid-engine-swaps-18/%2A-%2A-obd1-b-series-engine-into-obd2a-obd2b-civic-integra-%2A-%2A-1972711/

I have done the 3 wire to 2 wire IACV mod, I ran vtec and bypassed the pressure switch since I do not have one.

I have an obd2 99-01 b20 dizzy which is 8 pin like the the dizzy plug on my harness. The car starts, but will not stay on I have to give it gas for it to stay on. I am not getting spark in cyl 3 & 4. I checked my wires and changed them out for a new set I had in the garage. Still the same issue. Just to make sure I set TDC and the rotor is pointing at CYL #1.
I first had the CEL #15 for ignition output signal but that has gone away.
Then I had a CEL #8 TDC Sensor. That went away too.

I picked up 2 distributors from a friend to see if the dizzy was bad. One is obd1 and one is obd2 (10 pin) I de-pinned them and wired them to my harness and now cyl #1 isn't firing. There is no way 3 dizzys in a row are bad?

Any ideas? When I get home from work I am going to put my obd1 injectors in. Right now I am using the obd2 y7 injectors. But other than that I am stumped. Going to check if I am not getting fuel. I can't figure out what else could be wrong. Any help is much appreciated.

Thanks

 

Is the cel still on ,if so for what? Are these dizzy you used new or known working units ?
