2018 civic si won’t start (christmas tree)

[edmin]

I went on vacation the other day and my car was left in the cold for a few days. I get back to my car and it turns on fine. I drive it for about 20 minutes to the store and then come back to it and it won’t crank. All the warning lights come on and just flash. I called roadside assistance to jump my car and they said the battery looks fine. I also tried disconnecting the battery for about 30 minutes and that still hasn’t fixed anything. any help would be greatly appreciated. thanks in advance.

(the car has a prl cold air intake and a ktuner v2 if that’s any help)

Check fuses

on both boxes? or just the engine bay?

Dang sorry I had a similar issue and it ended up being a fuse for the ignition

CEL code?

charging system failure most likely has to do with battery sensor circuit. my guess would be rodent damage.

Check your wiring harness under the hood for chew marks and cut wires. Rats love the wires due to soy coating.

That’s like the third pump fuse issue I’ve seen on here in the past few months.
Glad you sorted it out !

I wonder why it blew in the first place...

update: I've had the fuel pump fuse go out 4 times now. last week after replacing the fuse the car still wouldn't turn on and I had to get it towed. anyone have a clue to why the fuse keeps blowing?

power wire shorted to ground somewhere
