Sos truck billowing white smoke out of tailpipe
So I was hooking up my DRL LEDs and now when I start my truck it is billowing white smoke out of the tailpipe. Everything was 100% fine last time I drove it. Its a 04 5.4.
Two things that happened
1. The battery arced really bad when I was trying to remove it so maybe a fuse? But IDK where to start.
2. We tapped a wire that was up where all those plugs are on the passenger side of the engine bay. there are 3 plugs up there, and on the far left one there is a black wire with a blue strip on it that had ignition power. Could it be related to that?
Thanks for your help.

I should also say the white smoke smells like gas and it is billowing out of the tailpipe so its not coolant.
Also no codes as usual.

I think it has to do with the arc the battery created. I guess I'll just start pulling fuses.

I checked all fuses and everything i fine. I guess maybe I have an injector stuck open??? The white smoke is obviously fuel....How do I diagnose this?

Are you talking about the wires for the PCM? Tapping into those just seems like a terrible idea. Undo what you did, and see if it still does it.

Still does it. Yeah I realize now it was a bad idea but its still doing it. I ended up having my insurance tow it and a shop is going to look at it. Seems like I have an injector or two stuck open or something. I don't even know where to start. I did't even have any codes.
