Angry No fire with Twin Tec on Softail

Ok so here's what I've got. OE 2000 softail harness with the TSM bypassed using a Grip Ace controller and Daytona Twin Tec ignition module for a 96" TC. To preface, this bike ran with this exact layout previously, then the oil pump went bye bye and it got replaced. Pulled oil tank and flushed it good. Now I have no spark during cranking. Checked all my connections behind it think something got pinched, cut, knocked loose, whatever. Bike turns over excellent on starter, got compression, battery voltage is perfect and all fuses are good. What I've checked so far:

Run/stop works fine, good power during cranking
Crank Sensor replaced, both old and new crank sensor check good
Check power to ignition module during cranking, checks good.
Power to coil at key on and during cranking is good
Grounds are good
coil was checked and replaced, both check good
No signal from the module to the coil during cranking
Bank angle sensor shows to send ground out to module (I can't find out if that's right or wrong, makes sense that it's correct though)
MAP sensor check good
Replaced Twin Tec module with stock HD module no difference (but it's a dyna/road king one and the part number is different, however no one can tell me if they crossover or not)

And yes it has gas in it............. what else am I not thinking of?

Did you replace the cam drive gear with one that was smooth and does not have the lip to trigger the module during the oil pump upgrade? If it's carbureted, the original gear had a raised lip 180 degrees around.

I though all 96 ci TCs were fuel injected so which DTT module did you use? Single connector or dual?

Wiring for the single connector model.

I read it wrong also. I suspect he has a 96 ci motor (07 to 10 motor). Since he is using a 2000 harness, it will be a 2 connector DTT module.

Will need to ground the tilt sensor wire but should get spark. IIRC DTTs will spark with the plugs out but only timed for the rear cylinder. He could try installing the plugs to see if it helps.. I'm not sure if Schroeder ever did a module with cam sensor but if he did the and the DTT is early he might need one..

Either way - looks like we're not going to find out...

I do have the correct cam gear and chain for the cam sensor to work. Ironically enough, I paid quite a bit extra to get that particular one and turns out I didn't even need it. The Daytona Twin Tec doesnt use the cam sensor. Stupid me.

Sorry, been slammed at work and forgot I made this post actually. I actually saw that I'm getting no signal out from the module to the coil, not just no spark. I worked my way back to it, instead of just jumping to it first. I am sending the module back to DTT tomorrow if I get the RA from them. Just sucks because it was fine before, just only made it a half mile on the oil pump lol. That's my luck though.
