Ok well i have a 90 4runner v6 4x4 that used to be my fathers and has given it to me if i can fix it. Its been sitting for about 2 years due to ecu problems, i fix the ecu, drive it to put gas in it and just shuts down, it wants to start but doesnt. I get the ecu looked at and they tell me its fine, i check the fuses, all fine, anything else i should check?

 

What exactly did you do to the ecu to fix it ?, we need a little more information to help you.
