2G No spark

[DSM_GSX01]

I have a 95 On my build I have no spark. I bought a harness from Ohm racing and been trying to see were I loose 12v at I loose it at plug on coil. Everything is fine up to there. I have no idea what it can be. I also put a crank angle sensor on the harnesses. Not sure if that can be it.

The 12v to the coil should come from the ignition switch/relay setup, then you need 5v and ground to your ignition transistor, you sir need a schematic.

Checked all that it's good. I bought my harness from Ohm racing. I asked them also they told me check some stuff and I did.

When I ordered the harness I went to a crank angle sensor. And the Ohm said I don't need a crank sensor at crank. So I'm not sure if something is wrong. Or what. Also I bought new coil packs thinking it was that.

If you have factory setup the 95 uses a crank sensor (CPS) and a CAS sensor under the intake cam sprocket. If you have a 1g in a 2g setup many people have the 1g CAS on the passenger intake cam that provides both signals.

I had the set up 95-96 under the sprocket and and at crank. But when I had them do harness I put the 1g set up in. But something isn't right.

I made some progress over my Christmas vacation. The battery was dying and I needed to figure that out so I found out there was short to ground on tail lights. But I also found a loose ground. Not sure. I have everything right I'm sure I went threw everything. Im not getting spark still. I went threw everything I could.

I just finished diagnosing a similar issue on my 1g. Found my ecu needs replacing or repair.

The charge capacitors leaked all the acid onto the circuit board.
