This may sound a bit unconventional, but we tow stubborn tractors that have sat all winter. Stubborn because they weren't put to bed properly. If your car has sat that long in warm weather then the fuel is probably a bit nasty. Try draining the sludge plug on main filter if you have one, pump it up by hand, plug it in for an hour or so if you have a block heater, pump it up again, then take it for a tow in high gear. Watch the oil pressure - if it doesn't come up then shut down and change the oil before trying again. Expect fuel filter plugging until you get fresh fuel through the system. I top off fuel filter with ATF when changing - document in maintenance log and keep jug in trunk as "red" fuel is farm fuel that is illegal for highway use.
