Hi, not sure if this is a good place to go or post this. We have a 94 gmc w4 (2500?). This thing has been a royal pita since we bought it. Engine has had issues, transmission had to be rebuilt you name it. Now that namely is because of the previous owners.
This however presents an issue for me as I have to fix the thing. I cannot find parts or info on these trucks to save my life. We have a 96 also thats techically an isuzu. Same thing.
Its like GMC (and isuzu technically) want to pretend these things never existed. Dealers pretty much tell us they cant help us and they have no idea what the things are or what parts they need.
I have the vin: 4KDB4B1A9RJ001182
Ive checked numerous places but every one tells me this vin is incorrect and doesnt exist. Same thing on our isuzu model.
9th vin number doesnt check out with the algorithm. Ive checked many times and thats indeed what the number is.
Im trying to get as much info about them as I can as this thing is insanely sluggish and runs poorly after a new alternator, plugs, wires, you name it. I was thinking maybe the timing could be adjusted? maybe the timing chain is going bad too, not sure its got over 179k miles.
I believe its a stock gm 350. Its paired with a 4L80-E transmission.
Any advice would be so helpful. Thanks.
Nick.
