I disconnected the battery to reset a check engine code, after connecting the battery to start the car the car won't start. The interior lights including the hazard light keep flashing for about 15 sec, stop for 5 and restart flashing. I read several forum that stated that the battery would most likely the cause of the problem. I connected a jump start to the battery to verify if the battery could had gone bad, but even with the jump start the same issue occurred. I tried disconnecting the battery and turning on the highlights to completely drain the charge to reset the computer. This had no effect on the issue. Please advice if you may have any idea to remediate this issue. Thank you in advance.
