One thing that'll make your life a lot easier, it looks like there's a Cotter Clip by the radiator support, and a support bar over the axle - those molded plastic fender liners look like they pop right out for much easier service access to the engine compartment. The tire is still in the way, but we can't fix everything.
TBI is like EFI - if any of the sensors are bad it won't go, and certain sensors it doesn't set trouble codes for - for example, if the Crankshaft Position Sensor goes bad the EFI computer simply thinks the engine isn't turning over. You have to hook up a voltmeter and look for the proper signals coming from the sensors as you crank it over.
Check for proper fuel pressures at the tank and at the TB - even if the fuel pump is good, a bad pressure regulator can choke it off, or shunt the fuel flow back to the tank on the return line. There will be a spec in the book as to how many gallons per minute it pumps, you direct the flow into a bottle and hot-wire the pump.
Change the fuel filter on general principles, but it probably is not the cause of a no-start - even if it's hopelessly clogged for pulling a hill (and you'll feel the drivability issues as it is starved for fuel) it would have to be totally cemented shut to not flow enough to start and idle.

Oh, and Right NOW you need to peel off the stickers / buff out/ paint over/ cover up the prior owner's name on the doors and the DOT numbers on the fenders. The prior owners should have obscured the name and numbers themselves the minute it changed hands, or required you to do it ASAP.
All sorts of unwanted excitement could come from that incorrect ID or DOT# - you for falsification of ID, or a cop runs the numbers and finds that the associated insurance policy with that DOT# was cancelled...
Either way, they now have the authority to pull you over to find out what's up, and they have the Probable Cause to start fishing for any spare change in your pockets - With visions of Dollar Signs dancing in their heads. SFX: Cash Register {Ka-CHING!}
