I broke something trying to install stereo

Hi. I'm Keith and I recently purchased a '94, gas 454 chevy, Safari Kalahari. It has very low miles and has been running perfect. I had been hoping to write in here about my various project ideas, but it seems that I've given myself a problem.
I was trying to install a cd player I had to replace the existing old cassette player. All the wires were labeled nicely inside. My stereo also was nicely notated as to the wires. I set it all up and plugged it in. The stereo worked for a little bit and I was messing with it and the quit. I changed one of the power wires trying to get it to come back on. I must have crossed the positive and negetive because now my rig wont start. The power went totally dead. After a while I tried it and it turned on and would turn over but wouldn,t start It seems like it might but no. I can smell gas and there is gas fumes coming out of the tailpipe. I ran the battery down and tried the boost with my house batteries. It turned over fine but would not start either.
Now it dead again. It will turn over with the boost but no start. I'm sure I messed up seriously. I'm taking time to think it out and I'm safe at home so there is no pressure to go anywhere. I'm going to take some pics tomorrow. Any help is appreciated. I will write more about how it happened and I'm going to think through exactly what I did but I'm having anxiety at the moment. I'm hoping I can find a fusible link or that I damaged the running battery or something like that.

    And it sounds like now it's flooded as well.

  • Ok, take a breath. Nothing you did would cause a serious issue except reversing wires on the stereo might cause its fuses to pop. Your battery ran down while you were messing about and that caused the stereo issue at first.

    If you have a generator or a charger then get the engine battery fully charged.

    If you were tying wires into the fuse box you could have blown an ignition control fuse. Since you can smell fuel and it turns over fast enough to start then you are missing spark. Sometimes fuses can fool you too.

    If you find some device on the fuse block that looks like it is used to tap a wire off it could be highly suspect. Some of those devices spread the fuse holder contacts and even though fuses are good you lose power. Use a simple 12 volt test light to check each end of every fuse. A test light is less than $10 in many cases. Don't use a voltmeter because they can fool you.
  • Unless you caused a dead short on the crank battery, (and I really can't see how you might have done that by swapping out a radio unit), I can't figure out what you could have done that would cause what you describe. Check all your fuses in both your engine fuse block and your house panel. Then, start from scratch by disconnecting the new radio and see if it cranks then.
