here is some back ground on the problem...my 97 cruiser would turn over but not start...long story short my husband took it to the toyota dealer and this morning i was told that it would cost a minimum of 3000 dollars to get it fixed because I need a new main engine wiring harness...i that something that has to be done at a shop? this is my only car...i have 3 children and don't have that kind of money.
