I found a good deal on a 1997 wrangler because the owner parked it a month ago and said it wouldn't start the other day. He says it has no fuel pressure and thinks it is either the fuel pump or regulator but doesn't have the time to fix it. The jeep is a solid 2.5 hours away from me so id have to go there and fix it so I could drive it back. I just sold my truck so I don't have a way to tow it. How easy/cheap should this be to figure out what it is and fix?
