Hello and welcome to JA, is the light flashing rapidly or staying on solid?
if i turn key back and forth alot or leave key on for awhile it starts low voltage on gage wen doesnt start truck was in flood a couple months ago just started doing this
the most likely cause for a rapidly flashing light is that the key is not being recognized...do you have a spare key that you can try?
its a 2000 not 98
does it have anything to do with key remote lock
no, when the PCM does not recognize the key, it will flash the theft light rapidly, you need to get a new key and have it programmed to the car..
