My nissan maxima 7th gen crank but won't start I changed the fuel injectors, fuel pump, new battery, camshaft sensor, coolant temperature sensor, new maf sensor, new spark plugs, new ignition coils and still nothing is working I have no clue wha else it could be I haven't change the crankshaft sensor but I don't feel like it's that anyhelp?

 

I'm in the exact same boat can't figure it out. But I also replaced my engine wiring harness!!

 

As some folks are fond of saying...test, don't guess. Are there any codes to help us get started? If not, how about old school Spark and Fuel Tests. Spray a bit of starting fluid in the throttle body. Does it try to start? If not, lets check for spark. Pull a plug and coil and see if you get spark when cranking. If not, we know we have and ignition/wiring/fuse/control problem. But let's do those basics. You really could use a scan tool or at least a code reader.
