2001 Buick Regal Just Shuts Off
2001 Buick Regal. Anti-lock brake light on sometimes. We have had this car almost a year. One day at a stop sign I turned the blinker on and the car shut off. Hard to move out of gear.
Played with the shifter enough and finally moves. Sometimes it won't start - the dash lights all blink on and off. If it does start the anti-lock and service engine comes on about 5 seconds after the car starts, but not all the time. And you can shut off the engine with the blinker.
We have hooked up the Solas scanner to it but it shows N/A. My husband is a truck mechanic, so he has checked everything with the battery. The computer we have for our cars shows no codes, maybe because its different every time we start the car. Could the PCM be bad and that's why it will not display codes?
Someone also told us it could be the alternator is going bad. He says the battery is fully charged so thats not it. We are thinking bare wires are rubbing in the steering column because the blinkers shut off the car. But why would it be hard to get it out of park once it is running.

OK. With these things checked and all the problems you are having, this sounds like a low voltage problem. This would also explain hard to get out of gear. Low voltage to the shift lock solenoid would make it hard to get out of gear. This is the item where you have to press brake pedal to get out of gear.
Also, if your Buick Regal has a floor shifter, it is possible the solenoid is contaminated with spilled pop or coffee. I have seen that several times. But that would be the last thing to check.
I will send some pics in a minute of the things i describe below.... A faulty ignition switch / harness assembly will cause these problems. Tapping of the switch in the column sometimes can cause it to act up, or correct itself. Also the harness end of the switch / harness under the dash could have a poor connection.
A rubbed through engine harness under the hood is another possibility. A harness can rub through on the A/C dryer, a bracket, or the corner of the radiator fan. Poor connections under the underhood fuse / junction block. There is a bulletin for this one, although have not had too many of them. Connectors can be poor under the block and cause several electrical problems.
These are the most common caused for your problems. Again, i will send some pics to go with the above info.
