Engine Cranks, But Will Not Run

DEFINITION: Engine cranks OK, but does not start. May fire a few times.

^ Perform "DIAGNOSTIC CIRCUIT CHECK."
^ Make sure proper starting procedure is being used. See Owner's Manual.
^ Visually (physically) check:
- Vacuum hoses for splits, kinks or improper connections, as shown on Vehicle Emission Control Information label.
- Ignition wires for cracking, hardness or improper connections at both distributor cap and spark plugs.

^ Remove the air cleaner and check carburetor choke valve, vacuum break(s), linkage and unloader operation. Choke valve should move smoothly and be closed when cold, and open when hot.
^ Check for presence of fuel by noting carburetor accelerator pump operation. Look for gas squirt in carburetor bore while quickly opening throttle lever. If no pump squirt, check for:
- Fuel in tank.
- Carburetor fuel inlet filter. Replace if dirty or plugged.
- Fuel pump capacity.
- If fuel pump checks OK, check float needle for sticking in seat, or binding float. If there is a pump squirt:
- Crank engine and check for flooding.
- If not flooding, see IGNITION SYSTEM CHECK (CHART C-4C).

^ Remove spark plugs. Check for wet plugs, cracks, wear, improper gap, burned electrodes, or heavy deposits, Repair or replace as necessary.
^ Visually check distributor cap inside and out for moisture, dust, cracks, burns, and arcing to coil mounting screws.
^ Try to turn distributor shaft by hand. Drive pin may be broken.
^ Very cold temperatures, check that the proper viscosity oil is being used. Check that crank case oil is not contaminated with gasoline.
^ EEC System may be clogged and/or flooding carburetor.
