engine not cranking?

[xka24detx]

this happens randomly, could be when the car is dead cold, or been driving for a while. ill try to start it and ill hear a click like the battery doesnt have enough power to crank, and ill just keep doing that, then after that about 5 or 6 clicks, it cranks out of no where, and if i kill it then try to restart, it starts fine. im thinking either battery or starter... im clueless... :hammer:

possibly a faulty starter relay?

what kind of battery do you have? my brand new redtop optima did that, i replaced the starter/alternator and found out my battery was just fucked up, it didn't have enough juice to start right away but after cranking a few seconds it would almost build up power to start it(don't know how else to explain it, damn deep cycles), it happend on cold starts usually sitting for 5+ hours.

If thats not the case, get your starter tested.
