Keeping in mind, I a noob, but I have a little experience, allot of reading, and I have searched CL EVERY DAY for IDI and have watched what sells and what doesn't.
Those symptoms are exactly the same as the first truck I bought where its PO told me it also needed injectors. Well it ended up having a dead hole. If someone thinks I could get my $1000 back out of it in parts, I would love to do that! I personally don't see it. So I sold it to a friend for $500.
IN MY OPINION. That truck is no money maker. Besides, the real money makers don't generally sit around waiting for you to buy them. Now if you want a nice truck to drive around and use, then it is probably a descent buy depending on the work it needs. Dead hole? NO WAY is it worth $1k. Not around here.
If you KNOW it is injectors and pump, and you have some good used ones for free or cheap, and that fixes it then sure you could me make a couple hundred. But if it is because of low compression u just sunk your $.
Now on the 86 in Eugene, it seems more like an easier fix, and possibly a better profit maker, (having not seen a picture. But then you MUST ask yourself. "If it IS such a deal, why does it sit and remain for sale". Well one reason is that an NA 86 SC 4x4 is simply not worth much more than $1k, maybe up to $2k in good shape.
