Noob needs help with 91 Amigo starting problem

[jstiff1]

Hey everybody, I'm new here although the archives have helped me on more than one occassion. I have a problem with my 91 Amigo. It has 156,000 miles and is 4 cylinder, but I'm not sure of the size. It is a 2 wheel drive if that makes a difference.

Lately, the truck has been acting like its running out of gas (sputtering) as i get to the end of a gear. It started doing this mostly on uphill ascents and then whenever i would get on the gas.

Tonight, it finally quit all together on a descent uphill grade and it has refused to start since.

It turns over just fine, but doesnt fire.

I know that there are a lot of options to check, but I was due to sell this on Wednesday. The guy was ready to pick it up. I dont want to sell a lemon or a dead truck, but if this is a repair that I can do, I'd just as soon make the deal.

What do you think? Plugs, distributor (does this even have a distributor?), fuel filter, fuel pump, timing belt?

Any help would be greatly appreciated. Thanks.
