Not a Mopar but I was wondering....

...what would cause a vehicle to not run after it was run out of gas then had gas put in? Fuel pump happened to go out from the heat?

The reason I'm asking, I buy cheap cars, when I have the money, to part out or if I can, fix and sell. I found a 95 Isuzu Trooper ls 4x4 5 speed with 190,000 miles, clear title for $500. Now, if I can't fix it I can part it out but if I can fix it I can generate a better, quicker profit with MUCH less work. So, what could cause this?
