Bought an 86' GMC Sierra 3/4 ton with a 350 and a new transmission for $1,000 back in December and it didn't run at the time. Spent $100 to get it towed to my brother's house and an additional $300 replacing the plugs/wires, hoses, filters, belts, cap & rotor, battery etc. Been running since then except it leaks/burns oil, leaks gas (replaced the line and fixed it), leaks transmission fluid.....all until this morning. I am scheduled to move back to my parent's house and attend college this Monday so Sunday is my last day at work. We had a meeting this morning and wouldn't you know it my truck dies at the stoplight (uphill) across the street from work. Put the break/signal on (while people are honking and getting angry) and ran across the street and got 2 guys help me push it across the street. Luckily I work at a Wendys that is in the same building as a Pilot station. Put gas in her and she still wouldn't start. Guy I work with said it was the fuel pump. Went and got one at Auto Parts ($21.96) and spent 2 hours trying to put the stupid thing in. Works fine now. Also need a new rear end there is something messed up with mine when I pop it into reverse it makes a horrible clang. Figured it was the U-joints but I bought some and went to put them in and when I was turning the drive shaft it turns out the noise is in the rear end the joints are fine. Go through $200 bucks in gas per month and I don't hardly drive around town and 10 minutes away to go fishing. Is it worth fixing the stuff wrong with it or would I be better driving it till she dies and part it out?
