No compression in #4

So just found out today that my engine is messed up and I have no compression in cylinder 4 but all other cylinders are good. What could this mean and how much could it end up costing also is there anyone that can help do the work? Or send me to the right person??

I took it to my electrically guy cuz the first person I took it too said it wasn't mechanical they must have not checked the compressor.

So anyway my electrical guys checked the compression

i'm guessing you mean your mechanic said it wasn't mechanicle and the guy who does computer related stuff on cars said there is no compression on #4 cylinder. No compression in a cylinder is a huge problem... It involves removing the engine and re-ringing a pistion at the very least... unless it's a head/valve problem.
