Check the Crank Angel Sensor

Check for spark, if there is none it's possible the ignition module is bad, but that's a generic guess.

It usually presses on the splined portion after removal and disassembly of the back half of the driveshaft. That means you'll need a press to get it off and then the new one back on. Amazing things can be done with hammers so I wouldn't write off that method but having it pressed is always going to be the easy way.

Dead cell n battery.. Or bad alternator

Under hood in auxiliary fuse control center

Most aircon system in any car usually has a sensor relay that the compressor will not continuously run if the thermostat are worn out ,if the clutch pack magnet wiring are grounded or worn out,if freon are low ,to find out which one is the problem go check the single wire connected to the clutch magnet right in front of the compressor where pulley and belt are located ,if you don't have a tester to find our that power are present all the time while. Using the aircon,you can bypass and hook another wire on it and hook it in the positive side of the battery ,while running the engine and aircon visually check the clutch magnet of the compressor if it will pop up ,if yes you have a worn out compressor magnet.

There is either a wire problem from the PCM to the transmission or the shift solenoid is bad or the wiring to it under the transmission pan. A scan tool would need to be hooked up and that solenoid turned on and off with the scan tool and see if when its turned on the yellow/black wire will switch to a ground when commanded. If it does more than likely the shift solenoid is bad, else, switch a ground the wiring from the PCM is bad or the PCM its self is bad.
