2003 Mitsubishi Eclipse Car Won't Run

Just did a Header swap on the car. Only had 2 o2 sensors plugged in (front mani). Idled the car for 20 minutes, took it out on the street. 1/4 mile down the car feels really sluggish, and @ 40mph the engine turns off. Since then I plug 1 o2 sensor back in, I replace my distributer cap, rotor, spark plug wires. I tried a Spark test and have NO spark. When spraying Starter Fluid into the air filter, the car gets closer to running, but won't. It does Turn over but won't start.

It does Turn over but won't start.

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light.

Fuel pump and Injector/s checks out-start checking the ignition system-power to coil, coil/s itself, distributor pick-up, control module, Cam and Crankshaft sensors.

If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems with compression and valves opening and closing at the wrong time

I have tried Starter Fluid, it sounds closer to running but doesn't. More starter fluid only made a gun shot from my engine, im done with that.

I did a spark check before and have NO spark. Since then I have checked my fuses, one was blown, a 20a fuse (on the map it shows a picture of the engine), I replaced the fuse but car doesnt run. I was thinking to do a spark check again since replaced.

Did a spark check. I HAVE SPARK

Check the engine compression and verify ignition static timing

Thanks for the suggestion. I actually ended up taking it to a shop so they can take a look.
They said it was the aftermarket alarm, so they disabled it. The car would then run. When I got to the shop to pick it up, I noticed it hasn't been test driven (i wrote down milage) I asked them to test drive it so I wasnt responsible for it breaking down.
Sure enough, we didn't even make it out of the parking lot. Engine shut off again. So I left it there to be fixed the next morning.

Thanks for the suggestions, rasmataz, but this isn't in my hands anymore, but hopfully in a professionals.
