Good morning all, I have a 2002 optima that I have been tasked with fixing. My paw-n-law was attempting to service his cars transmission when he was stopping off the trans fluid, the car died and would not crank. He replaced the fuel pump with no change. I placed my OTC Genysis scanner with only the crankshaft position sensor code. I replaced the sensor as well as new timing belt. No change. Come to find out the code was thrown because he unhooked it while spinning the engine over. Now no codes present. I have rpm through the scanner so I feel the crank sensor is registering. I have checked injector pulse which is good and I can hear the fuel pump energizing. The ecm relay behind d the center console was also replaced after researching the forums here, with no change. Paw-n-law purchased new coils to "help" with no change. I dont have an assistant to help with the checking the spark as of me typing this, so I cannot verify spark. Anything I'm missing that I can try in the meantime? Also i have a single wire near the camshaft senso that is dangling and i cannot find where it would plug in. Thank you all for any help.
