ok i was just trying to start my car... and when i turn the key the car doesnt crank.... is it my battery or something else? a week ago it was running but when i used the remote it wouldnt unlcok the car... at first i though the remote battery was dead but could this be somehow related? also one time i left my car on to lisen to music and it died.... but i kick started the car and has been working fine... so any clue whats the problem?

 

a- the remote fob will not unlock the doors while the engine is running.

b. there was no sound at all? if not then it is not a battery or starter problem. it is most likely eitehr an ignition switch problem or a neutral safety switch problem. either way it would be an ignittion switch circuit issue. check fuses etc make sur eyou clutch is depressed fully.

 

Weak battery. Trunk not fully closed and light on which drained the battery? Don't drive the car often enough?

 

does anything else turn on when you put the key to the run positioin, ie dash, radio, etc

 

neg none of the lights turn on or anything... (interior lights) i drive it once or twice a week usually...

 

car battery is dead, probably gonna need a new one

 

Whats a good battery to get? also how much do they run for? i only recall the yellow top?

 

One of the Mazda-recommended replacement batteries is the Interstate MTP-35 which goes for about $70. There is also a newer recommended battery, but I don't know the brand or model number. If you car is still under warranty, tell your dealer about your problem and they may replace the battery for free.

 

exactly and make sure they give you the new 640cc amp batery

 

or charge it

 

call mazda roadside assistance, tow the car to dealer, and dealer should replace battery with the updated one under warranty

your car IS still under warranty right? lol

 

The Optima Yellow-top 35 series is a great battery for this car. Especially if you only drive it infrequently. It withstands deep discharge far better than a conventional car battery. And, it's non-spillable so you never have to deal with corrosion or adding water.

Mazda does now carry a better battery than the original RX-8 battery so you might be able to get that at no cost.
