Damn this suck!

I know this question have been ask many times, I did a search already still don’t know what is the problem with my car I need help asap. here’s what happen, this morning I did some welding on the car’s door, after finish I went in the car to start it up the engine turns but won’t fire, I try start up again it then runs but only a second then die, no engine light nothing! this car is bone stock with 139K 5sp NOTE* I did the same repair to my other car nothing happen

Does not sound like the welding has anything to do with it, unless you shorted something? Does it idle rough then die? or what?
