Um.... You don't get to pick on the coolant line; It's either connected or you purge coolant all over while the engine is moving. I believe the source for that coolant circuit is part of the coolant hard pipe assembly which wraps around the engine.
The 4 pin connector may be for an auto transmission... If so it'll look dirty and worn all the way around whereas if it was connected to something previously it'll look like half is relatively clean.
The 2 pin connector may be for either a VSV (the ACIS VSV specifically which mounts to the middle flange connecting the upper and lower halves of the intake plenum) or the reverse light switch connector which runs along to another connector which is routed across the top of the transmission.
If the car is not cranking at all it's not the 4 pin nor the 2 pin plugs to blame. Check the two wires which run to the starter: Solenoid power and main battery power for the starter motor.
