Broke down 1989 trooper
Hello and thanks, I bought a 1989 trooper yesterday and it ran great while test driving handed over the cash and pulled out of the drive way and it fell on its face and died.
The problem:
I took it on probably a 10 minute test drive and it ran great got back turned it off then started it back up and it fired right up, so I turned it off handed over the cash the got in and left. I made it about a 100 yards and it start stuttering and died.
The thing will start up fine and idle(rough when warm) for ever but as soon as you touch the gas pedal it will try to die when you let of it comes back. it only does it when its warm. Also it seems like the low fuel light and battery light come on when the problem starts.
Once again thanks

Fuel pump?
It sounds like it is starved for fuel for one reason or another. The thing that comes to mind first is fuel filter(s) plugged up. The thing that might plug them up could be a dirty gas tank.
this is just really basic guesses on my part judging by the symptoms. Idles well because just enough fuel is getting through to keep it idling but when you open it up a little it leans out the fuel mixture and it stumbles.
if this is a carbureted engine it may also be a piece of rust or dirt in either the main jet or accelerated enrichment jet. If it’ll idle without the air cleaner on, an old mechanics trick was to get it as reved up as you can and then completely block off the air to the carb (us old guys just stuck our hands flat over the inlet) The idea being to make the engine draw enough vacuum to hopefully suck the blockage on through whatever orifice it’s plugging up. I’ve only owned one carbureted Trooper so I don’t know if any of this is helpful or not.
good luck

Broke down 1989 Trooper
My Trooper sat for 7 years (no driver's license). I changed the oil and filter and then drained the gas tank. The last of the gas was gasoline and sludge. Attached to the bottom of the fuel pump is a mesh bag that's probably inundated with sludge. You can remove the fuel pump and clean it or you can buy an electric fuel pump and install it in line between the fuel tank and a new fuel filter. I did this on an older Trooper and it worked just fine. Good luck.
