i just wired in my aem fic on my 91 240sx with a ka24det. the day i wired in the fic i has it running and was able to tune it well but the next day i go out to work on it some more and it wouldn’t fire up. it would turn and just crank but no start. i checked over my wiring and made sure nothing come loose or anything, even tho i soldered everything and taped it off. i was getting good readings for everything on my computer but i pulled a plug wire and i wasn’t getting any spark. i pulled the wire off the coil to the distributor and i’m getting spark there but not to the individual wires. when wiring up the fic i wired in my crank halo and hali wires in the to crank reference wires at first and it wouldn’t start so i connected the wires from the ecu back to the way they were before. i then tried intercepting the wires to the crank position sensor and it worked fine so that’s how i kept it to tune in. could something have went wrong there causing me not to get spark now? i’m stumped on what it could be and i really need to get her back on the road. any help would be appreciated!

You should switch to a standalone ECU, you'll thank me later.

its an Aem fuel ignition controller. its a piggyback tuning system
and its one of the two types of crank sensor which is hall or mag.
