D15z1(has the vtec-e) engine in a 98 civic. Me and my buddy has came to the conclusion that in the civic they have kept the obd2 wiring harness and obd1 conversion harness. We've sodered the dizzy so it plugs straight into the wiring harness (because we had to replace the dizzy) . its a z1 head and block with a jdm d15 intake manifold, we have a z1 distributor with a obd2 distributor wiring harness soldered together.

We were doing a head gasket on this car originally that had been sitting for about a year, after replacing the gasket, we changed the oil and filter, new spark plugs in, new timing belt, kept the old spark plug wires, kept old rotor cap, started out getting weak spark, changed the ignitor(screwed up the original one up), so we bought a remanufactured dizzy thinking that was the problem. Now we have no spark at all.

We have compression, fuel pump primes, main relay clicks twice.

What ive tried/checked.
Known good dizzy cap and wires off of a d15b7
Spare ecu(p28 5 speed, his car is also a 5 speed)
Checking fuses under the dash and under the hood. fuses 9, 13, 15, 18, 24, 27, 28, 33, 24(all that have any thing to do electrically) except Fuse 31 has no power (ECM/ PCM, pgm-fi main relay, intergreated control unit)
Re-check mechanical timing.
No CEL code
Changed ECU's
Checked and cleaned all 3 grounds.

Distributor terminal A: 12.15v -- terminal B: 12.15V -- coil spring 12 volts
compression check dry : 4(110) 3(90) 2(95) 1(110)
Ignition switch all checks out at 12 volts and above.

Fuse reference.

Im going by this chart but i have no yellow on the engine harness(obd2 plug) side and have no green wire on the distributor side(obd1).

On the engine harness plug for the distributor, with the key turned on(fuel pump primes, main relay 2 clicks, check engine light comes on for 2 seconds then goes off), with a multimeter, I tested each wire and this is what I came up with.
Blue - 0.15v
blk/yellow - 11.95v
white 0.02v
red - 0.02
black - 0.02
orange - 0.46
green - 0.83
blue - 0.44
yellow/ green - 0.02

Im getting no spark at the coil spring with a grounded wire to the chassis, holding it close with pliers while a buddy cranks. No pulse but a steady light(with a test light) at the A or B terminals on the distributor, and no pulse but also a stead light (with a test light) at the fuel injector clips when cranking and on start. My problem lays in the wiring at the distributor side not the engine harness side in my opinion, i just have to figure out how to wire it correct. Yall tell me if you think all the wires check out for voltage ^ and what you think about the wiring problem.

Why would you go threw all that trouble.. Take the harness and throw it away!!

Not my car man. and it would be more trouble wiring it straight up, extending wires without a harness than doing it this way
