Yes, it is the wiring to the little black box under the ecm or above the fuse box. Not sure what you call it, but it has two 4-wire plugs going into it. When i wiggle those wires; it clicks, then engine stops or runs very poorly. When i push wires to the left a bit, the engine starts and runs great.

1990 has a main relay that is really 2 in one, main and fuel pump and has more pins.
see it there.
top corner
any loose wire there, engine will stall.

if it has pink wire, that it is fuel pump, pink is dead giveaway of that. bad wire or bad relay .

note my drawing ,does not have the gross errors of the orig.
