Starting issues, will not stay running

Truck (1992 Pickup 4x4 3vze) has been sitting thankless for a few years. Purged out lines, replaced plugs, replaced tank and fuel pump, changed oil and went to start and turns over but not starting. Fuel pump would not come on when turning the key. Verified Ohm at AFM is between 200-6200 and moves freely. Does not turn on fuel pump. Supplied 12v to the pump directly and fuel pump turns on. Cracked lines at injector and cold start and has great pressure and good return to the tank. Tried to start again and barely ignites first crank or two for a second then shtus off. Will run if using either for testing purposes. Checked and brushed all fuses and verified continuity. All relays are good and tested. A2 30 amp fuses good and EFI has 12v, good spark to the new plugs. Possibly the injectors are all seized from them sitting? Lines were drained when tank was removed 7 years ago. Any advise would be great.
