2000 Chevy Monte Carlo Car wouldn't start twice

If you just get clicks, that sound like a sterter solenoid pulling in, it could be loose connection. The battery cables should be checked for tightness, as well as the battery cable connection at the starter. Sometimes the power stud on the starter solenoid can be loose. If all appears correct, it could have a starter that is malfunctioning. This could be more common when hot. The way to catch it would involve checking for a signal at the starter when it is failing to crank. If you are getting signal, it most likely is a starter fault.

I am not saying he does not know what he is doing, and this may not be the only cause for this type of concern. From what you described, the no crank with a clicking, it sounds like a poor/loose connection, or thermal concern. To 'check' something can be as general as a visual inspection, and I have no way of knowing how thorough the check was. If the problem was occurring at the time, a check would include some test equipment like a multi-meter or a test light. The clicking and not starting told me to start with the basics, the 'click sounds like turn signals only more rapid' may be another story. Focusing on the no start, the simplest approach would be to check the start signal at the starter solenoid, and like I say, if it is getting a signal, the starter is faulty. Did the check include scanning for any trouble codes? There is one bulletin that I came across that may, or may not apply.

Subject: 2000 - 05 Chevrolet WB Delayed Crank or No Crank

Models:

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in the PI.

Condition/Concern:
No crank or delayed crank, may be necessary to hold key in start several seconds until vehicle cranks and starts.

Recommendation/Instructions:
FOR A NO CLICK NO CRANK CONCERN:

If the BCM does not send the VTD code to the PCM, the PCM will not energize the crank relay even if there is battery voltage at the PCM on the crank circuit 806. The BCM will not send the VTD code until the ignition 3 is at or near 0 volts and ignition 1 is at battery voltage or if there is a power mode mismatch. NOTE: If there is a power mode mismatch due to a wire or terminal concern the BCM will not set a DTC if this occurs before the vehicle is started. If the engine is running and there is a power mode mismatch DTC B1440 will set. The ignition switch power modes should be checked on the scan tool and if necessary at the BCM connectors for correct operation.

FOR A DELAYED CRANK CONCERN:

If any after-market devices are connected to CIG/AUX fuse circuits 143, remove the device and re-evaluate the concern. These circuits are blunt cut and are provided to accommodate after-market devices. Refer to document number 859128 for the wiring schematic. Any after-market device that utilizes a capacitor as part of its electrical architecture can cause the ignition 3 buss to slowly bleed down from 12 volts to 0 volts when battery voltage is removed from the buss during crank. The BCM will not send the VTD code until this ignition 3 buss is at or near 0 volts. This bleed down can take several seconds depending on the size of the capacitor in the after-market device. If removing the device resolves this condition, the device must be removed or relocated to different circuits.

Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
