94 Caprice 4.3 V8 somtimes cranks and sometimes don't. There is a postive boost terminal if we wiggle it the car will start, then dies, again wiggle cranks back, wondering what to do

this terminal you refer to is at the underhood passengerside fire wall area...? if so this must be replaced..this has a well known issue of lossening and causing engine to stall not start..

this conects the battery to the FUSEBLOCK ..
