1980 caddy - just picked it up. the engine starts up alright, though the whole car shakes pretty violently as it idles. It held idle for around 10 mins before i shut it off. When i try to give it gas, it abruptly dies.
I don't even know where to begin, but am wondering if this is indicative of anything obvious. Any help is appreciated.
Most likely it is air in the system or a clogged fuel filter. Maybe both. Try replacing the filter (prefill it) and see what happens. You can also run it off a jerry can to eliminate the tank and lines to see if they are the problem.
