89 GMC stepside 4x4 worth? Urgent timeframe. Pics included

[bambbrose]

Sorry in advance!

I normally despise these threads, but I'm in somewhat of an urgent situation as there is a deal that probably will fall through if I don't act today/tomorrow.

I have the opportunity to pick up an 89 GMC 4x4 Reg Cab SportSide SLE w/ AC, 5.7 and 5 speed. I would be picking it up for a minor restoration but mostly to drive for a while, maybe sell in a few years, and enjoy.

He is selling it with the following diagnosis:

-runs on starter fluid
-doesn't start on its own
-bed removed and fuel pump replaced as they thought it was fuel
-owner is burnt out and just sold his home so he needs to get it out of there asap
-owner doesn't have time to figure out what is wrong

We know it has spark since it starts on fluid, so I still think its a fuel or injector issue. I'm great at fixing issues like this and confident I can get it on the road with a few hours of diagnosis.

There is minor rust in the cab corners, needs a windshield, and the body panels/paint are pretty beat up.
Tires are new, clutch is newer, and trans and 4x4 works great.
Owner says maintenance is up to date and he always took good care of it
Mileage unknown at the moment.

Very dirty, been sitting for 6 months.

What would you pay?
