Engine Cranks Over But Will Not Start Or Is Hard To Start

Important Information

1. First, determine which engine system is causing the problem. To make an engine run,

basic components fuel, spark (ignition), and compression are required. If all three

components are present, the engine should run. If any one of the three are missing,

weak, or arriving at the wrong time the engine will not run.

2. Determine if there is fuel present by looking down the carburetor venturi while actuating

throttle. There should be a stream of fuel coming out of the accelerator pump nozzles

if the carburetor has fuel.

3. Check ignition system operation. Remove coil wire from tower on distributor cap. Hold

coil wire near ground and check for spark while cranking engine over. Repeat procedure

with spark plug wires. If there is spark at the spark plug wires, remove the spark plugs

and make sure they are correct type and heat range, and not fouled or burned.

4. Run a compression check on engine to make sure the engine is mechanically sound.
