Engine suddenly turn it off when i came to a stop sign???!~

Hi all, i have a auto 2000 civic just had a accident few weeks ago, broke the radiator. annd i got everything fixed yesterday. after i got my car back, when i tired the remote start (by CompuStar), sometimes it will turn the engine on and turn it off right away. and sometimes wont even work.

when I went to a stop sign last night, i completely stop the car and after few seconds, the engine turn off by itself, but i still have electricity on power window and cd receiver. the Oil light and the Battery light was on.
I just got a new battery yesterday, so it shouldnt be the problem of the battery. When i turn the engine on again, it was fine.

after i parked my car, it shake it for 5 sec and came to quiet....

does anyone has this experience b4? anyone know what's wrong with the car? Please help! :confused: :confused:

take it back to the mechanic that fixed it.......they should know what's wrong with it

sounds like something wrong with your alarm.

its most likley a vacume leak

Some alarms with remote start have to be reset if the battery was disconnected. Especially if it has a tach less mode. This is done by unplugging the wire harneses from the unit itself. I f you have the manuel to the alarm refer to it. Or E-MAIL a tech at the company that makes your alarm.
