Have you a name perchance? Nice to address someone by their first name...
With respect to your game, the first thing to do is to remove the playfield glass and lift the playfield - the idea is to make sure that the plugs for the playfield cables are seated in their sockets on the realy board in the bottom of the cabinet. You will see these cables coming off the rear underside of the playfield going down to the bottom board. These plugs are the type you gently pull and rock back and forth - do not pry or twist them as you will break the plug or socket or a pin or two. At this point you can simply see if the plugs are fully seated in their respective sockets by pressing down on the sockets.
If you don't know how to remove the glass go here:

The game must be UNPLUGGED from the wall power when you go inside (you don't yet know what is dangerous - so unplug it for now).
Plugs all seated? OK, now check the same types of plugs in the headboard - take the back door off and find the cables coming up from below and check that they are fully seated.
Headboard plugs all seated?
Have you also reseated the coin door plugs near the inside left front of the bottom relay board?
Good.
Now what happens?
Have you got a schematic for your game? Have you any experience reading schematics - fixing car wiring, doing some house electrical reapirs, etc.?
Yes? Great - head to http://www.pinwiki.com/wiki/ and read up on troubleshooting Electro-Mechanical (EM) pinball games and then post back here what you find out.
No experience? Well, get the schematics anyway, and find some online info on how to read EM schematics. There are books out there that can be a big help. Pinwiki will still be a great help too.
