If your alternator tests good off of the vehicle, but will not charge on the truck you need to make sure that the supply wire has 12V and that the field is also getting 12V. If you track it down to the ECU you can save yourself a bunch of money by having an external voltage regulator wired in and bypass the internal ECU regulator.

You have a bad fuel pump relay under the hood on driver side. The relay is stuck wich is allowing power to flow to the fuel pump. If you operate the truck like this you will burn out the fuel pump.

You have a blown fuseable link under the hood. Look in the driver side you see wires wrapped up unwrap and check each wire. Replace blown wire and should fire up.

Probably a bad coolant temp sensor, inexpensive and easily replaced.

It could be coming from the timing cover. On older 318 engines there is a water passage on each side of the timing cover between the pump and the block. If the timing cover decays it can allow coolant to leak into the timing cover, which usually goes into the crankcase.
