Even if your battery is bad, a jump start will let you start your car. It just won't start the car on its own.

I did leave the cables hooked up and Civic was still running when I tried to jump start. I revved the Civic around 2k rpms for maybe 5 minutes, let it sit for another 5-10 minutes before trying to start the S2K.

Do I need to let it sit longer?

No, if it was hooked up to the civic while the civic was running, it should have sufficed.


First, check if your big fuses (the 60+ amp fuses that are held in with phillips screws) are confirmed OK. Physically remove themm and inspect them closely to see if they blew.

If the fuses are okay, you may have shorted your ECU by connecting the power wire with the ground through your OBD2 scanner device. If that's the case, you will need a new ECU.

Beyond the simple steps listed above, you'll have to go through the regular starting troubleshooting procedure of finding fuel,air,spark,timing etc.

Yo can also try using another car's battery to see if it will start the s. If it does, then the battery might be done for. It just won't take charge anymore.

Make sure it has around the same cca as the s battery.

So I finally got around to doing a quick voltage measurement on my battery with a multimeter. It read 12.51V, which I've read means it's at least 85 percent charged.

Is my next step to get the battery load tested at an auto parts store?

12.6 volts is a max charge on a sitting battery. It ahold be a good battery. Take it to an autozone it's free.

Yah, that would be next step.

Just dropped the battery off at O'Reilly. They said it wasn't charged, so they're gonna charge it then perform a load test. Going back in an hour to see the results. Fingers crossed! If it's the ECU then I'm screwed.

Problem solved. Just needed a new battery. The old one had normal static charge but wouldn't charge according to O'Reilly. Feels good to have the S running again!
