Question about 2002 Oldsmobile Alero
Hi my name is Yas i have a 2002 old alero 3.4L, it all started with the car having a no start, battery was replaced at that point car started up after driving a while all the dash lights and gauges starting coming on and off every so often the the car was shut off and would not start again i replaced the igniton lock cylinder and passlock assy and did the antitheft relearn car started right up but after a few seconds it acts the same erratic dash cluster and will not start after you shut it off always starts right up after the battery is disconnected for a few minutes im thinking the bcm needs to be replaced or reflashed any help would be greatly appreciated this car is driving me nuts
My daughter has the same problem and has been in contact with GM. The problem is the system, not the battery or fuel pump etc. GM has no direct fix or parts to repair. The battery disconnect/reconnect works best, its what a dealer will do and they reset the computer even though they find no error. Alero is also is prone to bad motor mounts effecting grounding which can cause the same problem. GM replacement mounts are the same as the problem mounts. Battery reset works here too. Since Olds is gone they won't invest, especially now. carry the battery wrench, drive it till you can't stand it any more and then trade in. Look at the net, its full of the same problem in multiple years of that Alero version. Shame its a nice car.
