Engine continually cuts out - 75 C3 350
jimandemma:
Todays update. Fitted a 7PSI Carter electric pump and new filter, Holley fuel pressure regulator and fuel pressure gauge at the Carb. STILL cuts out after about 20 - 30 seconds with trouble starting again. I have fuel pressure at the Carb of 6 PSI but engine sounds like it is slightly missing. By chance, checked the battery and was only 10.7 volts. I currently have the battery on charge to see if it holds voltage, could this be the problem? If not, I have new leads and a complete new HEI dizzy to replace the current factory HEI dizzy.
jimandemma:
With a bad battery, can too low of a voltage while running, load the alternator enough to cause a stall?

bfit:
It you have more than 10.5 volts while cranking it should run.
What's your vacuum like
Is this an automatic.

Hei ignition is not a lover of low voltage 10.5 v is way too low i'd investigate why it is that low car will run on alternator without battery. Voltage when running should be about 13 volts
jimandemma:
Car is automatic.
Not sure on vacuum yet
Haven't checked alternator output yet as car doesn't run long enough.
I'll check battery in the morning and go from there whether it is stuffed. If not, alternator next I suppose.
