HI THERE, need help, yesterday car was running great, suddently stall and missing, and stall, Tried to restart , buzzer sound and relay cliking no crank at engine nothing.
check the battery and getting 9.8V so the battery was very low, but will a low battery do that, Buzzer sound + relay cliking or got another problem ?
the doors were opened for 3 days so the battery was discharge at the begginning.

Get the battery recharged and tested. If over 5 years old just replace it. Make sure the alternator is working.Originally Posted by tiguido

Yes it could. You may just not have enough voltage to fully kick over the starter.

If your battery reads 9.8 volts without any loads, it is pretty much fully discharged. Yes that probably causes the relay to chatter.

If the power gets low enough, even the smaller relays can 'buzz'. Usually a high pitch tho...just enough power to pull the contacts together, which passes power to some device, which drags the power so low the points open...which starts it all over again.
Time for a battery check...

So the buzzer i am hearing clearly is not the car door buzzer but a relay buzzer cause by the low battery voltage.
right ?

Based on your description - yes. (But we are not there with you).
Either
a) disconnect the door buzzer
or
b) charge/replace the battery
and see what changes

Reiterating what David T pointed to in post #2 - make sure the battery is tested/charged. If it is OK or if you replace it then be sure the charging system is OK. Should be running at ~13-14 volts.
What likely happened is that the battery slowly lost charge during the time you drove it til the voltage dropped so low the fuel pump could not deliver enough pressure to open the injectors. That killed the engine. Then you found out that the starter wouldn't work (clicking relay), again due to the low voltage. Good that you got the voltage reading for us.
