checked all relays and fuses checked the fuel pump itself by jumping it to the battery every thing seems good there. where the pump connects to the wire harnness not getting any voltage. Any ideas out there?

Look at a wiring diagram for your truck. Start at the fuel pump and physically check the wiring. A wire may have been severed or shorted.

check for hot at the blue wire to ful pump connector with key on and the ful pump check connector jumped with a paper clip
or just jumper the conector and see if it fires up
if not then check for hot in the blue wire
if is hot and the fuel pump is not audibly pumping then you have a bad pump

Check the coiled leaf switch underneath the AFM (air flow meter) & air filter, if not pull the ECU codes & if no faults appear measure the voltages & resistances at each ECU (EFI computer) pin and compare with the FSM (factory service manual).
About half of the ECU codes stored on the first & second generation EFI Toyotas don't show a constant blinking check engine light therefore you must pull the ECU codes to see if a fault is registered.
To pull the ECU codes:
All 1980-1995 and including 1995 EFI equipped vehicle allow you to find engine and related faults by pulling the ECU (computer) codes without the need for a handheld OBDII diagnosis scanner,the sites listed below have the fault codes needed to pull the codes and the instructions on how to do it:

Pulling the ECU codes is the first thing I do to diagnosis a problem thereafter I reset the ECU to see if the same problems show up and if so I then take voltage measurements both with the engine running and not and compare with the factory service manual,I also close the ignition switch after a cold engine and also after a warm engine and compare them with the factory service manual.This technique will completely isolate your problem without having to do trial and error and it is the technique I use when repairing tv's,vcr's,home/car audio.
Any Public Library in your area would have the Factory service manual,Haynes,Chiltons,Mitchells,Clymers,Bentley and Toyota repair books.

1)buy a used one off e-bay
2)some Toyota dealerships may give you one or sell it for $10-20 (used) as most Toyota dealerships don't repair many old Toyotas and no longer need the service manual
3)some public libraries sell their old books as they are not in demand any longer
4)some free buy & sell classified papers,websites and bulletin boards may have some used ones for sale
5)some junk yards may have one laying around
6)some Toyota specialty garages may have one laying around and no longer use it as the vehicle may be too old and those mechanics probably have so much experience that they could publish their own factory service manual with corrections and "real world repair tips"
7)if someone has the FSM maybe they could scan all of the pages and post it on a site for all of us to download or view.
