you have a bad control module, and check that coil resistance, cause they will fire but not how it should!! should be a good strong blue spark, if not replace it!
Need a little more info. Is it trying (but failing) to turn over? What's it doing? has new battery and relay. just filled up the gas tank, it turns over and turns over, but wont fire. ends up wearing the battery down. even with a battery charger it wont fire.
you need to be more specific
your car is broke
68Pontiac lemans wont fire
because its on fire
because it feels like it
Replace the Flasher Relay.
More info needed, is there fuel? Pressure? Is there spark?...
check your links on the transmission cable.
