1996 Pontiac Grand Am Turns over, starts briefly then dies

Bought a 96 Pontiac grand am from my son, he just had the motor rebuilt 8,000 miles ago & has had loads of problems before and after particularly with the coil pack & plugs burning out. Two months ago all the warning lights came on, one or two at a time, checked everything, fine. Makes bell dinging sound while driving & clicking noise like blinkers from the left area of control panel occasiionally. Figured faulty wire in instument cluster. Month ago, start but wouldn't run, pulled fuse from anti-theft, run fine. 4 days ago, same thing, sat overnight would not stay running. Have replace the fuel filter, oil pressure relay, MAP sensor, cam. Sensor, fuel pump, ECM unit and MAF sensor, check catalitic conv. Have fire and will run when spraying starter fluid in it, so my husband insists the coil pack and plugs are fine. Also tried the 10 minute trick, leaving key on 10m then off 5sec. Before starting. Almost broke and really need to get it fixed. Thanks for any help.
