When does the solenoid fail on a Pontiac?
The solenoid operates normally, or when the engine is cold, but fails when hot. The solenoid normally requires about 50 amps, but when it is very hot, it will require even more current. The solenoid maybe defective, but a failure is normally permanent and not intermittent. Starting Controls
What to do if your Pontiac starter does not turn?
The solenoid operates but the starter does not turn (you can hear the solenoid click on when the start circuit is energized). Assuming the starter motor is okay, the switch portion of the solenoid is defective. A temporary repair can be made by disassembling the solenoid, filling/cleaning the switch posts and switch disc.
What causes a motor in a Pontiac to stop working?
A. Badly worn bearings in the motor can cause drag and result in faulty or no operation. B. Badly worn or broken brushes will cause motor failure. C. A defective armature, either electrically open or shorted or mechanically damaged by dragging within the case will cause an inoperative part.
Why does my Car start intermittently after starting?
In this case, it’s important that you contact a mechanic as soon as possible so they can determine what is causing the intermittent contact. In many cases an intermittent starting problem is linked to a bad wire connection that may become dirty due to exposure under the hood.

What causes a Pontiac starter to not turn?
A defective armature, either electrically open or shorted or mechanically damaged by dragging within the case will cause an inoperative part. D. The starter motor may rotate, but the engine will not turn. This indicates a defective starter drive gear. E. The starter/drive gear may engage one time but slips the next.

How many amps do you need to start a Pontiac?
The starter requires 550 amps, depending on engine size and compression ratio, to correctly operate it. A weak or discharged battery or inadequate wiring cannot furnish that required amount of power. When the system is switched on the following may occur: A. The engine turns very slowly and may quickly stop. B.
