94 explorer wont start

[IrishCharm]

Ok ill try to make this as detailed as possible. I have 94 explorer it has been reliable for the most part, about a month ago it started having starting issues Id spray a bit of starting fluid and it would start right up also I could bang on the gas tank and that would work also. so I thought I need to replace the fuel pump before I did that I checked the air filter and my son-in-law broke the heater control valve did a temporary fix on it till I could get a new one the next day then my son drove it until the fix failed the car over heated and he pored cold water right in to the radiator with out letting it cool down now it wont start at all when I turn the key I do hear the fuel pump whine I also checked the oil it does not look milky but I did see some oil in the radiator thinking it might be blown head gasket and hoping it is not a cracked head do not have the tools to check every thing like gages and such is there a way to find out what exactly the problem is iv worn the battery down now and only get the click, click, click sound. any help or should I put her down.

little dissapointed

Im not a supper mechanic but I can follow directions very well I cam here to this site to see if I could get a little help in troubleshooting the situations I am having 35 views and not one bit of advice. I hope someone might have some sort of advice soon in the mean time I will continue eliminating what I can.

The usual things I would start with:

1) fuel -- just because you hear the fuel pump whine does not mean the fuel system is doing what it should. Put a fuel pressure gauge on the fuel rail and see what the fuel pressure is (see fuel pressure mini-diary).

2) spark -- Us an inductive timing light or other tool to see if the spark plugs are firing.

3) If you are concerned about a cracked head or blown head gasket preventing it from starting, then I would suggest a compression check.

Those are the things I would start with.
