Hey guys i got a problem and i'm not sure where to start or what to do. I have a 91 pathfinder with over 200,xxx on it. It's been running fine here lately, except one day i went to crank it over and it wouldn't start. I turned the key off and then tried it again and it fired right up. Well tonight i got off work and drove home, then about 10mins later went out got in it, started it and backed up and then it just died. Now i can crank it and crank it and it won't start. I can smell gas and i pulled one of the plug wires out and it's sparking. I'm not sure where do go from here, i thought maybe a fuel filter but i have no clue where thats even located at or anything like that. What do you all think it could be?

 

Nobody have any comments at all?
