Try pulling code/s from the computer light or no light
Cranks but no start-Do below to determine if its fuel or spark problem.
Disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,cap and rotor /distributor pick-up coil, ignition control module, ECM,Ignitor cam and crank sensors- Note: If it doesn't apply disregard it

There are three fusiable links at starter that may have burnt. Fuseable link looks like wire but burns up to protect. Two come off large starter cable and one off small solenoid wire. If they are burnt then no power to Ignition. Need test light To check
