4runner was running fine, sat for about 2 years, battery went completely dead, put new battery,drained fuel tank, put new fuel, blew old fuel out of fuel lines with air pressure, changed plugs, checked compression(125psi) on all cylinders,diconnected exhaust(incase it was clogged up) checked timing, even tried starting fluid, it will turn over fine - but will not crank. is there some type of computer problem that may need to be reset? I have tried everything. 95 forerunner V6 EFI

Because the engine turns over means your started had enough voltage to turn ON. You can easily test the voltage on the battery with a volt meter. It should be about 12.0 Volts when the engine is not running. Batteries should normally be charged every few days for about 1/2 hour each time. You can go a short time for a couple of weeks without charging as long as you don't get in to a habit of doing that. If you went for months without running your car; I assumed you had to replace the battery already or your battery would not have been able to turn over the engine or hold a charge.
The automatic door locking is the least of your problems. It might be your car did not have a battery of proper voltage for an extended period of time.
Gasoline does not age well if you did not place any additive for prolonged storage. Even the additive for prolong storage says about a 6 month period. Maybe you should take out some gasoline from your tank to see if it still looks good. I normally don't fill my tank but every 1 to 2 months (without a problem) with no additive added, but 1 year is a long time. My guess is 1 year old gasoline may have changed over time and thickened and it could have contaminated your fuel system.
Depending on how old and how much fuel is in the tank can affect your next step. If the fuel is the problem; you will have to drain the tank and possibly have someone use one of the pressurized fuel cleaning treatments. You might need a new fuel filter, and I know there is a pressure regulator to return the fuel to the tank as well as fuel injectors and the fuel rail. I have never had gasoline that old, so you might need a professional mechanic if you are dealing with old fuel in the system.
The only gasoline I trust to age over time is Coleman fuel in a sealed container (also known as white gas). This can be found where they sell outdoor camping equipment. I don't know if that will help, but I had to run 1 gallon of this in 1992 Oldsmobile 88 because there was no gasoline. Coleman fuel is ultra refined gasoline without the extra additives they normally put in gasoline.
Sounds like you got a tank of bad gas. That would easily cause your issues. Start by draining as much as you can, put a can of Seafoam in there, add a few gallons of fresh gas, drive to the gas station and tank up, and run that tank down until your gas light comes on before adding more. You may end up needing a fuel filter or plugs again, but with minimal run time on the bad gas, you'll probably be fine.
Put in some dry gas. If it sat for a long time , condensation, water, could be the problem. Add some new gas too. If you can siphon out the old gas first, that would be good. Change the fuel filter. If it still starts and stops, check the fuel pump/pressure. Test it at the fuel rail.it is fuel injected, right?
could be the fuel pump ...you will need to do a fuel pressure test on it ..the pressure should be 63 anything lower even so much as a few lbs will cause this to happen ...as well if it sat that long i would consider a complete tune up and check all vacuum lines for dry-rot
Your battery is either faulty or ther is a parasitic drain, have it checked out at parts house. With a good battery installed, spray some starter fluid into intake housing. If it starts, then dies, you have fuel pressure/delivery problems. Can you hear the fuel pump run when you turn on the key? Hope this helps.
