Car turns but wont start, electrical problem??
 

Ok so I know my car was running about a week ago. I start it every week. Long story short, it got towed and the battery had to be jumped last time so I knew the battery was dead. Anyways when I got my car from the impound lot the guy hooked up the jumper cables backwards, I was sitting in my car at the time and the hood was up so I couldnt see him. He told me to go ahead and I cranked it and there was a buzzing noise a some white smoke came out from under my dash. I was like WTF??!! I told himt to swap them and he did and it wont start. I gota new battery and replaced the spark plugs too.The car cranks like its trying to start but it jsut doesnt start. When I go to turn the car over, the commander on my Power FC goes blank, which isnt normal, but when I let off the key to crank it it comes back on like its booting back up. Also when I crank the car my fuel pressure guage doesnt move at all now. It has a fuel upgrade kit for 1680cc secondaries. Any ideas as to what it may be? Also I have to get diagnostics on this shit and take it to them before they'll pay for the repairs. Any suggestions or ideas are appreciated. Whata bad f*ckin day........

Check all your fuses. If there was smoke, chances are something fried. Do yourself a favor also and double check your spark plug wires. Make sure they are on correctly.

FWIW, my PFC commander goes blank on the first crank too.

Turns out it just blew the main fuse. I know I shoulda checked them first off, but man it was sucha bad day. Thanks for the tip tho.
