1965 Impala Wont Start

The car will turn over but I cant get it to fire.Its a 327 small block.I replaced the distributor last year so it is allmost new.The cap is older.I have had the car 3 years and I havent put a new distributor cap on.I drove the car yesterday and it was fine.It started right up.I parked it in my garage and then today I went to start it and it wont start.How does this happen over night?.I checked everything and I dont see anything disconnected or anything like that.Is there any way to test the distributor to see if it is bad?Any help would be great.Thanks

Do you have gas coming from the accel pump nozzles when you pump the pedal?

When you drove home last night, did you hit any water in the road? Points style caps are very suspectable to water vapor condensing on the inside of the cap, sending all sparks to ground instead of to each cylinder.

Do you have spark? Pull the coil wire from the cap and put the end next to some grounded metal and have someone crank the engine. It should be sparking to ground. If there is no spark, pull the cap and have someone crank the engine. Doing this, you can make sure the rotor is turning. If not turning, you have big problems, ie: timing chain or dist gear is loose.

If you have NO spark anywere, verify that you have voltage with the key "on" going to the "+" side of the coil. If NO voltage, check the ballast resistor that should be mounted on the firewall behind the dist. Its a white looking ceramic block with a wire on each end, one end going to the dist.
If you have voltage on one side of the resistor and NO voltage on the other end, the resistor is bad.
If you have NO voltage going to the resistor, you will need to back trace to the ign switch to find the break, or the switch could be bad too, but not a very common problem.
If that is good, next verify that the points are opening and closing when cranking. Biggest problem with points and no spark is a bad condensor. Rotors and caps don't usually go bad over night.

If you have spark at the coil wire, plug it back in and then pull a plug wire off one plug and insert a screwdriver and have someone crank it over while putting the shaft of the screwdriver next to grounded metal, it should be sparking. If you have spark at the coil but NOT at the plug end, the coil wire is most likely bad, but again, a wire does not just crap out sitting there not running.



Its possible that the coil is bad too, but not that common. Do the above tests and let us know that happens. Its probably something simple.

Would it be bad to just dump a small bit of gas in the carb and then fire up the engine? I've done that a few times. If it fires up, you're not getting fuel. If it doesn't, check the distributor.
