Is it only active during cranking or does it spray until a certain temp?
1) Power applied to starter (cranking only)
2) Coolant temperature below a preset threshold ... below 95° F per the '88 FSM.
3) Within a variable time-out limit which depends on coolant temperature ... ~8 seconds max at -5° F per the '88 FSM, warmer => shorter time-out.
