Replace paper element air cleaner if necessary. Idle adjustment or automatic choke service (other than that outlined in paragraph D above) should be performed by your Chevrolet Dealer.
If the above Fuel System checks and the checks suggested under the Electrical System following do not correct the malfunction, it is recommended that you return to your Authorized Chevrolet Dealer for further checks, adjustments or repairs.
ELECTRICAL SYSTEM
If, when the ignition key is turned to "Start", the engine will not
turn over, you have good reason to suspect electrical trouble.
NOTE: Never remove Delcotron bat lead without first disconnecting battery ground cable.
(F) When there is no response at all to attempts to start the car, check the obvious-your AUTOMATIC TRANSMISSION SELECTOR LEVER must be in Neutral or Park position before the engine can be started. Turning the IGNITION SWITCH rapidly back and forth several times will sometimes correct a poor internal switch contact.
(G) The BATIERY may be discharged. If so, lights will be dim and the horn will have a poor tone if it will blow at all.
Usually
a garage recharge will be necessary to return the battery to operation. Occasionally, however, a long drive will recharge the battery.
NOTE: If the battery is determined to be dead, and for no apparent reason, have your Authorized Chevrolet Dealer check the
battery, the GENERATOR and the VOLTAGE REGULATOR. GENERATOR trouble should already have been indicated by the gene~ator indicator light on the instrument panel.

POOR BATIERY CONNECTIONS may be suspected if the car has operated properly a short time before and now not even the horn will operate. Check both ends of both battery cables. If the con
nections are corroded, a car may sometimes be restored to operation by removing all cable ends, scraping all contacting surfaces clean with a pen knife, and reassembling. If the cables are broken,
they must be replaced. The power supply should now be restored unless the battery is dead.
(H) If, however, the lights and horn work properly but the starter will still not turn over, check the STARTER connections. A "click" from the starter solenoid indicates that the wiring to the starter is properly installed. If the wiring seems to be clean and tightly installed, the trouble is probably in the starter itself and should be referred to your Authorized Chevrolet Dealer.
When the engine will "turn over" but will not start, the following items may be checked along with the Fuel Systems Checks listed
previously.
(I) With a clean dry cloth, wipe the ceramic portions of the spark plugs dry. In particularly damp or rainy weather dampness may be the cause of not starting, especially when the engine is cold.
(J) Check the cables at the top of the distributor and coil as well as each spark plug cable for tightness.
(K) If the car will still not start, check for spark at the spark plugs in the following manner:
Pull one of the spark plug wires off its spark plug. Insert a
short piece of bare wire (such as Distributor and Coil Cables

The wiring circuits in your 1971 Camaro are protected from short circuits
by a combination of fuses, circuit breakers, and fusible thermal links in the
wiring itself. This greatly reduces the hazard of electrically caused fires in
the automobile.
