2000 CHEVROLET TRUCK

Hey guys! I am in a bit of a pickle with my 2000 Chevy Impala with 169000 miles. When I try to start it, it does not crank, like it could be the solenoid but my mechanic that works on my fleet of chevy impalas say that it is something else. The battery light was flashing about four or five months ago. Also, if the car sits for a while (two or three days) it may start once or twice and then it wont start after that... Could the voltage regulator cause this issue? All of the lights work normal, radio works also.

Before trouble shooting any type of starting problem you should may sure the battery is fully charged. After charging battery make the following checks. You should read a minimum of 8 to 9 volts with the engine cranking. If not replace battery. Next make sure all battery and starter connection are tight and clean. #1 cause of starting problems are dirty or loose connections. If you still have a problem have the start bench tested to make sure it is good. As far as the voltage regulator causing this is unlikely because you say it only happens sometimes. If the alternator wasn't charging the battery the car would not start after the battery goes dead. If you like while you have the voltage meter out check the output of the alternator. Should read between aproximately 13.5 to 15.5 with the car running. Hope this helps

The connections have been checked and checked again, and the battery is charged and has been load tested. I also failed to mention that it doesn't crank. and now it wont start at all. Chevy thought it may have something to do with the security program, so they ran their program and it didn't fix the problem. When the issue was intermittent it didn't crank, and when it did crank it would start and run fine. The headlights dimmed at idle enough to easily recognize, but now the car just wont start.

sounds like the starter is bad. Before replacing it make sure you have voltage going to the solenoid when the key is turned to the start postion. If voltage is present, then this elimates the starting circuit from being bad which means the starter is.
Good luck BYM :)

With the battery charged and connections already verified, check for voltage at the starter solenoid with the key in start. If voltage is present, the starter is bad and should be replaced. Alternator output of about 13.5 to 15.5 volts can be checked once the engine runs; a voltage regulator is unlikely to cause an intermittent no-crank.

Conversation Summary

A 2000 Chevrolet Impala with about 169,000 miles would not crank, sometimes starting after sitting and then failing again. Lights and radio worked, and a flashing battery light had occurred months earlier. The owner asked about the voltage regulator. After confirming a charged, load-tested battery, clean tight connections, and that a dealer security procedure did not help, the expert said to confirm voltage reaches the solenoid in the start position. If it does, the starter is the likely failure.
