1995 crank but no start situation

[Armand]

So I picked up this 1995 ford mustang and it how to parasitic draw so I took care of that and I replaced the fuel pump. We jumped. It took it for a test drive. It was nice. Disconnected the battery put it on the trickle charger. Reconnected the battery today. Went to start it and it started up for like 2 to 3 seconds then it died now I have a crank but no start situation. Any help
