Blacktop S13 sr into s14

Did swap about 3 months. until yesterday it ran great.

All i was doing was cleaning up wiring from the swap.

I soldered o2 sensor wires, and maf sensor wires. After that, now i hear no fuel pump prime. Also, not getting spark. Ran fuel pump to a switch. and still will not start. It turns over, but not getting any kind of spark.

My multimeter took a shit on me, so i'll be picking up another tomorrow.

Couple questions. Is there any fuses i coulda blown that relate to the fuel pump and spark. the only wires i touched were o2 and maf. And i just soldered the shitty twisted mess i had before.
Not quite sure where to go from here. Ran/ started fine before i touched wiring.

I have searched, and thanks for anyones input!

tested power on both sides of ignitor chip. only gettin power to side with 4 wires, not the side with 5.

Does that mean ignitor chip is bad

did you unplug the battery when you soldered the wires?

same problem happened to me, check all your wiring and see if theres any shorttage, check your egi fuse to see if its blown.

ended up being fried ecu. so if anyone knows anyone with an e5 ecu let me know.
lesson learned. unplug battery when working on wiring. i shorted some power wires on intake mani during the process
