what are the symptoms of a bad crankshaft position sensor?

just bought car a couple days ago car would start but would have to pump the pedal to get it started would idle rough but drive fine once it got going i fixed the vacume leaks and the car would start right up and was idiling smooth i then was replacing old rotted speakers which have power to them and shorted the wires to the speakers and blew fuse to stereo upon trying to access stereo i might have knocked a wire loose. also installed is some makeshift ignition that would start the car but could be suspect. checked power to ignition module and module to coil and there is power to coil but nothing coming out of coil and fuel pump dosen't come on when trying to turn it over sounds like a job for the mensa mechanic

How do you change front brake pads on a 1990 Audi 90

whenever i use my heat, my battery volt goes down and things start to shut down. the car doesn't stop on me, but when i turn it off, i need a jump to restart. it seems to run ok during the day, but night time is a big problem, especially now that it is cold here. i'm in st. louis missouri.

i had the battery and alternator checked at autozone and was told nothing wrong with them.

please help. thank you.

About two years ago, I parked my 1988 Audi 90 (5 cylinder) for about two years. The last time I started it was about six months ago. It started right up and ran fine. When I went to start it the other day, it would not start, however, fuel is being pumped and leaking out from some undetermined location in the engine compartment and streaming all over the ground. I am unable to see exactly where the fuel is leaking from. Do you have any idea where the origin of this fuel leak might be? Thanks!
