Please help ! Just bought and drove 7-8 miles lost all power and shut off. ?. Changed filters and fuel.
What can I try. I don't know much at all about Diesel but can't afford a Mechanic.
 
What engines will fit ? ie... Toyota 22 R ? Toyota T-100 ? ? ?
   Thanks for any advice Mike

While it is not a Subaru ( a diesel is a diesel in that they all work the same way) my diesel Rabbit did the same thing in a parking lot one night.
 
  On top of your diesel injection pump there should be a single fine electrical wire going to a fuel cut off switch. Now either that wire has either broken off, or in some cases, the plastic covering has cracked off so it grounds against the fuel pump. This is a "hot" wire. It cannot come into contact with ground. It connects to a small nut which is the solenoid relay to cut off the fuel(otherwise your diesel will never shut off). You in fact can run a wire from the positive post of the battery to the solenoid and connect it that way to see if the solenoid is good - and then try to start the car. It should start if the solenoid is good. In order to shut off the car you need to disconnect the wire from the battery.
    This tells you the solenoid is good; so the problem is electrical and could go back as far as the ignition switch. I do not believe you would have a fuse inline but that is a matter to check in a repair manual.

Hello,
     I have a 1996 Trooper 3.2 automatic that has had a never ending battle with engine racing. Every once in a while it will operate at a normal RPM, but usually it is way over 2. It will go down the road at 30 MPH with no foot on the gas. It has had countless parts replaced including the computer. It has ice cold air, and the heater core is now bypassed. However, every once in a while it will start blowing humid and hot and then proceed to overheat. Sometimes going down the road the gas will spit/skip a little. Sometimes it really doesn't want to start and sounds like it's flooded. All of these problems are intermittent, but I have to wonder if they are somehow all connected. Any ideas of one part that would pertain to all?
      On a separate note (I think) the transmission does not shift smoothly and has never had much power. Any help would be greatly appreciated.

#68 of 73 Shivering '95 Trooper by filibogado

My Trooper has 140,000 miles on it. Recently, the engine and transmission powertrain started shaking and shivering when I accelerate, especially after starting cold. It seems to me that the engine and transmission components are tugging at each other, so I get this rumbling, hesitating response from the drive train, much like riding a buckling bronco. I can also see the engine rpm fluctuating within a narrow range around 850-950 rpm while stopped with the automatic transmission engaged in drive position. Once I step on the gas, the hesitation and push-pull among the engine and train components start again, and the engine threatens to die but has never done so. In sum, I would describe it as a combination of rough idling and shifting that has to be experienced first hand because its hard to describe in words.
 
I have topped up the transmission fluid but that did not help. My next step is to drain the fluid and replace the filter, or have the engine tuned up, or both.
 
Any suggestions would be appreciated. Thanks.

Has anyone swapped engines in a '95 Trooper...i.e. taken the isuzu out and put another brand of engine in the trooper?

Which one is more efficient? What's the advantage of DOHC?

My Trooper has 187k on her, and has started the same shuddering/sputtering when under load, as described by "filibogado" in the below post:
