Just finished putting a new fuel pump in the 86' 4Runner and It started up and ran for literally 2 seconds before it stalled. Now I go to turn it over again and no power to anything, won't crank lights on dash some times come on, but usually its all dark. Battery is fully charged no fuses are blown, I just can't find the short if that's what it is. I'm done for the night this thing just pisses me off. Any suggestions?
