On my 99 maza millenia 2.5, It looks like I flooded it this morning
at --10 below.
I know better but I pushed down on accelerator(a no-no) and then no fire at all. It had tried to start before that.
I've let it sit for Two hours and tried again(this time didn't touch the pedal) but to no avail.
Is there a way to start a fuel injected flooded engine other than
hauling the car to a repair center? Help!!

Re: Can't start flooded(?) car
Yes there is ,press the accel pedal down all the way and hold it there while cranking ,this will put the ECU in clear flood mode and it will stop injecting fuel .Don't crank it for too long as you ma damage the starter motor .
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

P0421 code is that the cat. converter is below efficiency. 99 per cent o the time the cat. needs to be changed. but if you have a scan tool watch both bank 1 O2 sensor 1 and bank 1 sensor 2. cold they should be almost the smae but when its at operating temp, and running down the road at crusie speed the frt o2 should switch rapidly between .150 mv. and .850 mv. and the rear o2 should read about .600 mv. if they read the same the cat is ng and will have to be replaced.
You connect a fuel pressure gauge like this to the pressure rail. Pressure in this car must be between 35 and 45 psi. If pressure is too low look for kinked fuel lines and eventually replace the pump. If the pressure drops down more than 10 psi in five minutes or if the pressure is considerably higher than that replace the fuel pressure regulator. Below the parts that may need testing:
Does it sound like its spinning or turning faster than normal? If so could just be flooded. Try cranking engine with excellerator 3/4 way down at 10 sec intervals with 2 min brake in between. These cars have always seemed to flood easy. And the air intake system is so enclosed it cant really dry out easy. I try that 3-4 times if it does seem like its trying to start or getting better than Id say tow to mechanic. Possible coil problems too? But seen alot of them flood out.
sounds to me like leaking injectors or fuel pressure regulator. Think about it -- you have puff of smoke (rich condition) and on a cold morning after sitting 8 hours theres no such thing as too much fuel. after sitting 15 minutes the rate of leak down isnt enough to flood it. but in 1-6 hours enough fuel leaks down to the cylinders to flood it (engine still warm enough to not be needing that amount of fuel without stumbling and chocking on it)
there is a switch on the clutch linkage. you can see it if you look under the pedol it looks like a black cylinder that slides along the clutch shaft. when this breaks you can't start you Jeep.
Mine broke I had to wait 2 weeks for a replacement part.
oh yeah( it clicks when you press the clutch) so you know it is broken.
