Is the ground wire from the battery to the engine block tight and clean. If you want to check battery draw put an amp meter inline between the negative battery post and battery cable. If you find a draw you can start pulling fuses until it goes away to find which circuit is drawing the power.
A voltage drop test of all the battery & starter wires may also be in order. Also do a voltage drop test of the cables to the starter during cranking.

hi when i put the amp meter between the neg post and cable to you leave the positive on the post ,because when the pos is on the post i think that just loops everything and i get the same reading as normal.

14V is good - alt ~should~ be working...
Do you have any aftermarket electronics (alarm, radio, gauges, etc) that may not be wired or working right?
With car turned off, disconnect battery and connect a 2 amp battery charger (or other charger on low current) to the battery terminals (not the battery.) Look at the current meter. Start pulling fuses to see when or if the current drops to 0. If fault is not found, some connectors here and there will need to be disconnected / reconnected.
