HELP!! Won't start Evo 4
Hey y'all I just swapped a 4g63 in my Evo 4 because my last engine had walked the crank bad... So I picked up a another engine with 75,000k, got fuel, spark, compression, an voltage. It's firing somewhat but won't run. What should I do????

its burning fuel in cylinders 3, an 4..... cylinders 1, an 2 have spark but are not burning so there full of fuel. the car wont start. it rolls over sounds like its about to start then it locks up(from all the un burnt fuel i thought) ive changed cam sensor, fuel rail, coils, plugs, throttle postion, checked timing.

im having almost this same issue, except sometimes plugs 1 and 4 fire and sometimes they dont. 2 and 3 just have no spark. hopefully you get this figured out. it'll help me also. good luck.

o2 sensor checks if you need more or less fuel.
maf sensor is stuffed. just unplug it, because the car can run without it, it will run with default values instead.
fuel pressure and injectors are likely to be fine.
coils could be dodgy. easy to swap out with some others to try it.
when you join pins 1 and 4 on your diagnostic port, what longs and short flashes do you get on the deashboard?
