Need Help! So it all happened when i did the valve cover and spark plugs but did not change the ignition coil, a week later while driving it i pulled it on the streets then a few minutes later it started to misfire, got on the highway i noticed the rpms started to get low and my engine losing power then the engine lost power. Then once i pulled over on the side, i tried to turn on the car it started but it had a rough idle and after a minute the engine would shut off. Now its been two weeks since its been sitting and now the car doesn’t crank up and turn on anymore, tried to scan my car with a cheap and expensive scan tool both couldn’t even read the engine data. Any suggestion or fixes i can do lmk.

Sound's like the battery has gone dead after sitting. You'll need to charge it up, then get it started again. Then use the scanner to find out which cyl(s) are misfiring.

did you guys plug the connectors back in for the coils or are they damaged or wiring? I just did this with mine after i foundout i had 0 compression. All the coils were bad, the plugs cracked in half. Check with the battery, and replace all the coils for 200$ imo
