sounds like it. but you could always check the basics before spending a bunch. Check your: battery cables, no corosion or loose fitting. make sure your battery is good and full, pop the caps on the top of the battery and pour in some distilled water if the fluid is not 1/4 of an inch from the top. check all fuses ect...

could be alternator not charging, put another good battery on and see what happens ,if it starts then check charge with a induction amp meter ,as these vehicles use intelegent charging system so disconnecting the battery with engine running to see if keeps running so you know alternator is ok doesnt work .if warning light goes out then renew the battery but if engine management light on then it could be a alternator fault or the ECU playing up ,and to check this out you wwill need a scope to read the fluctuations on teh sensor wire to the ECU and read the resistance to check for a fault as these vehicles use encrypted software to make it a dealer only job but it can be checked without it .

Check out how tight are the battery terminals. If you can move either of them then this is too slack. Next check the earth strap from the engine back to the car body. Again this should be good and tight with bright metal to metal contact. If everything is OK then check the voltage of the battery it should be about 12.5 volts. If 12.1 volts the battery is severely discharged. If about 10.4 volts then your battery has lost a cell and you will need to change your battery. If battery is OK then check out your starter motor and the connections to it. Initially give the motor body a clout with a length of stout timber when trying to turn the engine over. If the starter motor kicks into life and turns the engine over then it is likely that the starter motor carbon brushes need replacing.

Has the charging system (Alternator) been tested for proper output? Is the battery ok, have it tested. Autozone (and others) do this test for free as well as checking the Alternator output, it is one of the two causing the problem I'm sure. If the charging system is ok the voltage measured at the battery at about 1000 RPM should be at least 13.4 volts D.C.
