No start/stall 06 Mustang V6

[johnathan25]

I recently purchased a mustang for pretty cheap from a family friend, known issues were that the cats needed to be replaced because they were clogged. I recently replaced the cats, however immediately after replacing the cats it's having an issue with starting. It started fine about 6-7 times but is now having an issue with stalling out immediately after starting or just not starting at all. I did a full tune up on the car, replacing spark plugs, wires, fuel filter, air filter, cleaned maf sensor and throttle body, changed all fluids, hoping that would fix the issue because it needed a tune up anyway but it's still having the issue. It has compression, it has a spark, and it's getting fuel, I'm at a loss. Any help would be much appreciated!

Edit: It's also not throwing any codes!

Double check the wiring to the coil. One side is in numerical order but the other isn't. People frequently mix up the wires when they replace the plugs and wires.
