Default LT1 fire a no go? help

ok, I had leaned it out last year do to running so rich it fouled out the plugs in 10miles last year. fixed the harness that the tech smashed under the valve cover...completely severing the power to the 0xygen sensors. FIXED that.

just put new plugs in it put wires back where they went and fired her up. sounded great. turned her off and put the suspension back in. now 2 weeks ago when it was 23deg out I went to fire her up and she huffed a couple times but would not fire. thought plugs were fouled out again...and could smell un burned fuel in exhaust. took a plug out...looked fine. charged the battery up.....next day 35degrees....fired right up and let her run for 30min.

NOW....yesterday I fired her up and let her run. sounded like it was on 4 cyl. then died. noticed my voltmeter was in red. I disconnected the alt.......tried firing it on battery. only 2 small puffs in the exhaust. then nothing. smells like raw fuel again through the exhaust.

I replaced the dist,coil,wires all last year. they maybe have 600miles onm them.

I just dont get it. I put the battery back on the charger. I pulled the alt out to test it.

any help would be good. it was 40degree out today.

well took the alternator over to work. tested bad diodes. upgraded from the 124amp, to the 140. just put it on. tried cranking her...still a no fire, but I got more huffs!!!

I checked the coil.....sparks!! we have sparks. checked each wire. still have sparks!!! checked each plug on the drivers side. no fuel on anything. hmmmmmm. I have a half a tank of gas. is it possible the fuel is frozen? shoulda picked up some heet while I was at work. if it is warmer out tommorow morning...and if it fires....I'm drivin it to work.

I have checked all the fuses,relays,coil,wires,plugs,connections,inside and out. fuel pump does kick on when key is in the ignition. hmmmmmmmmmm.......
