Electrical Mishap 91 Metro

I have a 91 prizm that having a dead battery, caused by a dome light left on was being jumped by a charged battery that was hooked up backwards. The ignation was turned to start, nothing. It blew the 100 amp fuse on the positive battery cable. Replaced fuse and now have power to ignation switch but it will not start. Checked all other fuses and they are fine. I can get it to fire while jumping from my running truck but its killed when turned back to run. I sure could use any and all help. Thanks. Rick.

Chances are you fried the ECM or PCM
