My 91 trooper won't turn over. Please help!
 

Hey guys. I was driving my trooper uphill and as I inclined it just shut down on me. I tried starting it and it would rotate but not turn over. I'm getting no spark in the coil/module.
First thing I checked was the spark plugs And they we're all black so immediately I changed them and still I got nothing. I thought for sure that was it. I now think it could possibly be my fuel pump but not 100% sure.

Any knowledgable people out there with Advice please lend a hand
Thanks !
