Have you tried unplugging the negative battery terminal ? This question should have been posted in the evo engine/turbo thread section or the evo general threads.gl

When you replaced the ckp sensor did the car start after that? Is the car cranking but not firing? Or not cranking at all?

If it cranks then you need 5 things for an engine to run. Compression, timing, fuel, air, and spark. Start by checking those. If you recently did the ckp sensor then it's most likely your timing may be off a little bit.

If it doesn't then check to make sure your start motor is getting ~12v, it is grounded properly, and with the key turned to crank the signal wire get around ~5v. If that all checks out the check the clutch switch beneath the clutch pedal. Unplug it and see if the car will crank.

p0335 is for the crank position sensor
p0113 is intake temp circuit high (wires probably shorted somewhere causing this code)
p0108 high input in maf sensor circuit

If you've rewired everything well clear the codes and see if it will start if it doesn't then it's something mechanical most likely. The p0335 code will prevent the car from starting.

Put a spark plug tester on the coil boot and rule out spark. Then go from there gl

Maybe when the wires were rubbed raw you blew another fuse? Start from the necessities and check them off.
Spark? coils, plugs?
Fuel? pump running, pressure at rail, injectors firing?
Compression? self expanatory
Timing? off?
air? Leaks, vacuum?

You said no spark at the coil correct? If you have a local near by try swapping coil packs. Could be the Crank sensor as well. electrical problems are the worst. At least you know where your problem is though.

Just saw that you replaced the crank angle sensor. Maybe the cam angle sensor?
