Huyndai sonata 2004. Left inside light on for 7 hours battery went dead. Was jumped by AAA, truck. Car worked, drove home, parked it, tried it on again, it died. Mechanic looked at it, starter burnt out. Starter changed, new battery placed in, car still does not work. Mechanic said coil (4 cylinder car) gets power on 2 not on all 4. No one can figure out what's wrong. Could it be fuel injection, car computer. Any thoughts. When I tried turning it on first time, it would turn on but when pressing on gas pedal, rpm went up and just dropped and car died.

Check and test the crankshaft positon sensor-

Do below and get back with some testing results

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, If you can hear the fuel pump come On- check the fuel pressure with a fuel pressure tester designed for your fuel system to rule out the fuel filter/fuel pick-up strainer/fuel pump/pressure regulator and also listen to the injector/s are they pulsing or hook up a noid light and see if it flashing, If you don't hear the fuel pump, check the fuel pump fuse and fuel pump relay-Depends on what type ignition system is yours, No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, camshaft and crankshaft position sensors and computer Note: If it doesn't apply to your vehicle disregard it meaning if it doesn't come with one ignore it and continue testing
