Engine continually cuts out - 75 C3 350

(1/11) > >>

Hi guys and gals,
                           seem to have a problem with the engine cutting out at idle after about around 2o seconds of running and when driven, intermittent coffing and spluttering then stalls when you come to a stop. I originally thought it may be a blocked fuel filter, but after inspection, appears fine. Fuel pump all good also. When it does cut out at idle, it's instant, so doesn't appear to be fuel related. Car has been running like a clock with no evidence of a problem before this started. Could this be an electrical problem, maybe the distributor? I can't see any arcing around the cap or from any of the plug leads. Any help or advice would be greatly appreciated.

Cheers, Jim

Hot wire the engine to start , that will by pass all the electrics then you will know  where to start to look.

When you say "checked the fuel filter" - on my 78 350 Quadrjet there is a small inline filter on/in the carby body where the fuel pipe enters. You need to remove fuel line (use two spanners) from memory it is paper, I assume your 75 would be the same, maybe "bfit or sirfixalot" could comment. Also check "bowl" for water. Not unusual for tanks to fill with water, fuel floats on top. Sorry if I'm preaching to the converted, sometimes little items can be over looked. Good luck.

When you say points, I assume it is a basic points systm (no electronics) check points, if in doubt I allways change leads, cap, CAPACITOR and points. That leaves nothing to chance and will ensure long life. Oh! Nearly forgot - the Ole COIL  v8's can be notorious for crossfire, start the car in the pitch dark and look for cross fire at the plug, leads and cap and coil. Be aware you can (on some cars) see the plugs fireing down in the cylinder.
