The cause of this trouble is usually in the starting system.
If the starting system is not at fault, check for a hydrostatic lock or a seized engine as follows:
Remove the spark plugs, then attempt to crank the engine with the
|
starter. If the engine cranks, It Indicates
that water is leaking into the cylinders. Remove the cylinder head(s)
and inspect the gasket(s) and/or head(s) for cracks. Examine the
cylinder block for cracks.

ENGINE CRANKS
NORMALLY, BUT WILL
NOT START

Check the fuel supply. If there is sufficient
fuel in the tank and the proper starting procedure is used, the
cause of the trouble probably lies in either the ignition or the
fuel system.
To determine which system is at fault, perform the following test:
Disconnect a spark plug wire. Check the spark intensity at the end of the wire by installing a terminal adaptor in the terminal of the wire to be checked. Then hold the adap-tor approximately s-in. from the exhaust manifold and crank the engine.
IF THERE IS NO SPARK OR A WEAK SPARK AT THE SPARK PLUGS
The cause of the trouble is in the Ignition system.
To determine If the cause of the trouble Is in the primary or the sec-ondary circuit, remove the coil high tension lead from the top of the dis-tributor, and hold it approxi-mately 3/16in. from the cylinder head, With the ignition on, crank the engine and check for a spark.
If the spark at the coil high tension lead is good, the cause of the trouble is probably in the distributor cap, rotor or spark plug wires.

If there is no spark or a weak spark
at the coil high tension lead, the cause of the trouble is probably
in the primary circuit, coil to distributor high tension lead, or
the coil.
IF THERE IS A GOOD SPARK AT THE SPARK PLUGS
Check the spark plugs. If the spark plugs are not at fault, check the following Items
Manual choke
Check the choke linkage for binding or damage. Make certain the choke plate closes when the choke knob on the instrument panel is pulled out and that the plate opens when the knob is pushed in.
Automatic choke
Check the position of the choke plate. If the engine is hot, the plate should be open. If the plate is not open, the engine will load up due to the excessively rich mixture and will not start. If the engine is cold, the plate should be closed. If the plate is not operating properly, check the
