The ballast resistor can be bad but it will still start and run for 3 seconds or so becasue the fuel pump is getting power from a 12 volt source on cranking and then switches to the ballast resistor in Run.

ha yeah these old conectors don't seem to hold up to well I am starting to go through and replace all the basic connectors now to prevent this type thing again i go through a lot of water and mud time to get her sealed up.
Also if R. Center could give us an update on where he is at.... Have u narrowed it to fuel or spark issue yet? If so everyone might b able to give a better idea how to help
I just spent two months trouble shooting
End of the line was I had a bad connection on my ballast resistor.
You should test your resistor test your relay and check your conectors if they are corroded at all snip it off and put a new one on. I tried scraping mine and it didn't solve it after I rand a hot wired directly to the fuel pump i discovered that's where the fault was new conector and it starts right up now
Lots of this ballast connector crap happening lately, huh? Just happened to me.
