Greetings!! Started my 69 Fury the other day and while I was letting her warm up she just all of a sudden died. I don't think it's a fuel problem as it was like someone just turned off the ignition. I changed out the ballast resistor and inspected the cap/rotor, but not sure what to check next as she still won't start. Lights, turn signals, etc. are ok. Any ideas as what to check next would be appreciated!!! Thank You

 

Next cheapest thing to try is the coil.

 

You coil brand will have a primary and secondary voltage that you can check with a 10 dollar voltmeter. I posted it on here before so do some digging. I prefer to spend money on tools instead of replacing non broken parts.

A quick triage of the big three should at least narrow the issue (Spark, Fuel, Air).

Confirm Spark at the plug. You can do this with a cheapy glow case inserted in line with the plug. If it doesn't exist work the spark train backwards.

A VERY slight spray of Ether or a mist of fuel past the blades with a attempted "start" will confirm lack of fuel issue. If she stumbles and runs then you have a fuel issue ( delivery, pressure, contamination...

Dont discount a closed or non opening choke.

 

Sorry if I missed something but does it turn over?

 

Check your timing, the plastic cam gear is notorious for failing.

 

x2 on checking out that coil. the cool thing about coils is, they either work or they do not. there is no in between.

 

The first thing to check,, is it getting fuel and spark. I have had coil problems,, After running a engine for a bit,
turn it off and the car would not start back untill the coil cooled down..

 

Check if it's getting fuel...
Take a flash light look down the carb throttle bores and pump the gas see if the accelerator pump is primed if so good chance your coil is bad.
i have had old coils get hot and loose their spark. i have never had one just quit on me, but when they got hot they started too loose spark, missing. back firing
i have had one leave me on the side of the road for a hr till it cooled off and then she limped home...
That was my pertronx's distributor frying the coil's and it's self "several time's"
my wife had a Nissan maxima station wagon and when the coil got hot it would slowly ever so slowly turn the engine off it would just loose power until your on the side of the road..

 

Sorry, but this is absolutely not true. Coils can develop such things as internal shorts between coils of either winding which degrade the spark energy, but may allow the engine to run some of the time. The engine / vehicle may run, cruise, and drive, but fail when hot, or under hard acceleration.

IN FACT, you cannot check a coil for an absolute decision as to "good" using a multimeter.
