I have a '77 with a 6.6 L 400. It stalls with no consistency. Sometimes while engine is cold, sometimes while warmed up. At idle and driving. Sometimes it will fire up again right away and sometimes it takes hours. Other times it will purr for hours smoothly. While it won't start, I've checked spark to all cylinders and the coil. Its got spark and I can see fuel being injected in the carburetor. Should I check fuel pressure? What about vacuum? Thanks in advance!
