Please help! buddy's 85 coupe with nos

[90dpscoupe]

Friend of mine bought an 85, pretty clean, it has a carburated 302, a dp holley, edelbrock intake, some good heads,(not sure brand) and a lopey cam, longtubes, also a 10 lb bottle of spray, he just bought the car, and went to put gas in, shut off the motor, came back and tried to start it up, it acted like the battery was drained? i do see pullies on it, and i can tell he has the (race)crank pully, we tried to jump it for the longest time, and it just turned over, and tried to kick every now and then, but no pop?

So we even tried starting fluid, didnt help? I ran some codes, got: 22 24 and i think 26, but nothing major, This car does have a msd 6al box with blaster (old style) coil on it, but it seems to have spark so
we pulled one plug and it was very fouled (black), but not sure if they all are because its dark now so we are gonna wait til tomorrow, i do also hear the fuel pump working.

Guys, anyone, all the stang experts please help, thank god i have fuel injection . He's pretty down about this, but i told him i'd talk to some cool stang fellas here
