You mentioned the strong fuel smell at startup, so there is fuel, but maybe not under the right pressure. I would start doing the fuel pressure check first.
Also when a new fuel pump is needed, you could just change the fuel pump cartidge and not the whole module. Will be significantly less expensive.
Is this coolant sensor tied in with the gauge on the dash.
