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 kind of starter motor does a Pontiac have?
The starter motor is a very high current and powerful direct drive electric motor that rotates and turns the engine via the ring gear (flex plate) when the solenoid operates. The starter includes the starter drive gear that is equipped with an over-running clutch.
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.
How does the solenoid work on a Pontiac?
5. Upon release of the ignition switch from the “start” position, the solenoid reverts to a normally off condition. The solenoid return spring causes the high current switch to open and pulls the starter gear out of the ring gear back to its normal off position.

Engine blocks have a stamped two-digit letter code in this period; the Firebird’s 350 H.O. should have either “WN” (manual) or “XC” (automatic). The same spec engines were offered in the Tempest platform stamped with “WV” (manual) or “XU” (automatic) codes.
What makes a Pontiac Firebird 350 h.o.different?
Differentiating the 350 H.O. from its base two-barrel counterpart, however, was–first and foremost–its four-barrel intake and corresponding 750-cfm Rochester Quadrajet, as well as a dual exhaust system.
What was the last year of the Pontiac Firebird?
All are easily serviceable by experienced mechanics. CHASSIS In 1969, the semi-unit-body Firebird was entering its third and final year in its first-gen configuration.
Where are the cylinder heads on a 1969 Firebird?
Cylinder heads are usually identified by a casting number found over the center two exhaust ports, and as previously mentioned, the ’69 350 H.O. should have #48 heads. Be mindful of the driver’s-side exhaust manifold. Those used on the Firebird H.O. had a center outlet design versus the rear outlet configuration used in conjunction with the A-body.
