1987 mustng lx 5.0

hello, i have an 87 lx, it has been sitting for about 5 years, not ran at all. when i parked it, ran fine. i did a tune-up, plugs, wires, cap and rotor. it turns over, but wont stay running. it wont even run off an ether start. anybody have any ideas???

Is the battery new, too? If not and you recharged it, what voltage do you get with the engine off?

Does it fire at all?? How about with the starting fluid? any reaction to that? Are you using the 5 year old gas??

yeah, sorry, the battery is new

Did you use a fuel stabilizer? The gas probably turned to varnish and plugged up the injectors. Maybe the pump and fuel pressure regulator, as well.
