Just bought a used 1989 Delta 88 Royale Brougham. It worked fine but when I got it home and plugged it in (its winter) it won't start now. It turns over but won't stay running

is this a diesel? surely not. the plug in heats the oil in the oil pan to make the engine start easily in wintertime. you may have a faulty plugin, or if someones installed a deisel motor, you most likely have bad glow plugs,hmmm if gas, i suggest you check for faulty oildipsick heater or bad or weak fuel filter,fuel pump, it really makes a difference whether it's deisel or gas. please repost if this does'nt help, thank you for choosing
