my 74 f350 sat for a week, the engine is a 351m or 400 ,not original to the truck. I started it. it ran for about a minute with my foot on the gas to warm her up. i backed off the throttle she just quit fast, and wont start now.

i have power to the coil, and the test light lights up from negative on the coil to positive on the batterie. i did go to napa and buy and replace the coil anyway .

it gets gas to carb and i spray either and nothing,

i thought maybe i flooded it, let it sit overnight and today no start.

its raining now but what is next to try? thanks

 

Well, if it won't fire with ether, I'd look to the ignition system next. Sounds like you verified that the coil is good; check to see if you're getting a spark.

 

yes i will when the weather breaks. i am ttrying to get a jump on what it could be.

thanks

 

well i just tried to get spark from the coil wire grounded to the block and no spark.

the coils is good.

what should i try next?
thanks

 

What type of ignition are you running ? Points , Ford duraspark , MSD ...? Sounds like an igniton problem for sure .

 

old school points, should i pull the distributor or change points and condenser first.

can the points just stop working like that ? thanks

 

Yes , points can stop just like that . Get a new set of points and a condensor . Check the wiring coming out of the dizzy while there .

 

thanks, i will change out the points set , and post back my results.

 

One more thought ,,, make sure the rotor button is turning while the engine is cranking ...

 

If it don't then the timing chain popped, correct ? Thanjs

 

Timing chain or gear ... or dizzy gear sheared or loose . Hope the points and condensor or wire inside the dizzy is grounded out .... Best of luck ! Let us know what you find .

 

Try to use genuine Autolite condenser and points, the replacement points available today are mostly junk and the condensers even worse.

 

Will the points be junk if the condenser wire is grounded, even after I fix the short ? Thanks

 

No, the points would've ok.

 

I personally wouldn't invest too much time & money into making the old school points & condenser work when there are so many electronic ignition options available.
