  I have a 1994 Trooper. I have about 247K on it. I like it a lot better than the older ones... the Chromed ones. The Chromed hulks were low on power and not as well built in my opinion. The '94 doesn't have an AIcCR BAG... thankfully. I hate them. Does the '95 Trooper have currently working A/C... What's the physical condition of the vehicle. $2,200 is not a bad price... ...

  My name is Tony and this is my family's 2nd Isuzu product. The first was a 1994 Rodeo (stock base 5speed model) in 1995. It took us 15 years to purchase our 2nd Isuzu. We recently purchased a 94' Trooper LS. I purchased it for $1,250 with 4 bad tires and a very loud slapping timing belt and a rusted exhaust. I've owned a few trucks, but out of them all ...

  Your transmission will only fit the 2.6 engine. The 2.8 has a different bellhousing, and the 3.2 has one that is different from either. There used to be adapters made to fit other engines, but my understanding is they are no longer made. I would stay away from the Isuzu 3.2 V-6. You will need the complete computer system to install one of these including vehicle speed sensors from the transmission. ... Read More

  Just got an estimate to have a used transmission put in my car for about $2200. The Trooper is still drivable, but acceleration from a stop to about 30mph is very slow. Feel like I'm really stepping on the gas and not moving fast. Seems to run better in the cold weather, but I'm in TX so not much of that here. It has 120K and seems to running okay otherwise. ...

  I have the same model, DOHC. The bolt is a bear to loosen. I use an impact but I had to remove the radiator to use it. I have since seen where if you CAREFULLY use a long breaker bar and wedge it against the frame or other hard point and then quickly bump the starter it will break the bolt loose. I suggest unplugging the connectors to the coil packs ... Read More

  Well, It is tough to diagnose from a distance, but I looked at the charts, and as you can see below, the first chart refers to A (emphasis added)leaking fuel injector as a possible cause of low pressure (at start up). I kind of wonder how they tested the fuel pressure; do you get a cloud of black smoke when the trupr does start, as you might expect if the cylinder ... Read More

They did a "power flush" of the injectors and it started right away for about 1 day and it's now back to hard to start. They now have told me that it will need all new fuel injectors (approx. $1300). Does that sound like a final fix to my problem? How ... Read More

  Hi, you have taken good care of the vehicle, and my first guess based on your description would be a fuel problem too! That being said, a fuel guage can be hooked to the fuel rail, but it is hard to get to. There should be fuel pressure almost instantly when you turn on the key, and if memory serves me, it should be around 30#. When you turn the key ... Read More
