YOU NEED TO DO A COMPRESSION CHECK, YOU MAY HAVE A BLOWN GASKET THAT IS SO BAD THAT YOU ARE LOOSING TO MUCH COMPRESSION FOR IT TO START.

I suppose I would have to take it somewhere to have that done? I don't mean to sound ignorant but I am.
It is not a big job, a person with a little understanding can be talked through it, you just need to get hold of a compression tester, you just remove all spark plugs and screw tester into plug hole and crank to get a reading.

Just out of curiosity, have you verified spark and fuel at this point. If it sounds like a normal engine when cranking, not uneven or excessively fast, then I would start basic and check spark and fuel. If you at least verify spark, then spray some starter fluid in the throttle body and see if it fires, this is a quick check to test for absence of fuel pressure or injector fire.
I'm too much of a novice to know how to do that. Pointers?
Remove the air snorkel from the filter housing to the throttle body, open the throttle plate and spray it in. Just a few blasts and see if it starts. If it fires, you have a fuel issue.
cheepest way is to replace the head gaskets.take the heads to the machine shop to check for cracks and replain the heads.if cracked you need a rebuilt head to replace it.if you keep on driving it your going to blow the motor.

@gstacey....how do I do that?
Do you know where the air filter is, and perhaps how to service it? There are a couple of metal buckles that secure the lid to the housing, you undo those snaps. There is a hose clamp loosened through either the use of a standard flat-bladed screwdriver, or an 8mm(5/16") nut driver or socket. This will allow you to remove the fresh air inlet to the motor. You may also have to disconnect the electrical connector to the mass airflow sensor. You will see the throttle plate, rotate it using the throttle cam, that the cables are attached to, spray in the bore, and crank it to see if it fires off of that fuel source. If it does, it will only run for several seconds and die. This would indicate that you have no fuel getting to the motor, either by lack of fuel in the tank, no/low fuel pressure, or no injectors firing the pressurized fuel into the cylinders.
Ok so my neighbor came over and we pulled the three spark plugs I couldn't get to and have replaced them. He said it is getting spark and there is compression. Also, when we try to turn the engine over, it sounds like the water is boiling in the coolant desk our but it is not. He also said it smelled like gas fumes coming from the coolant reservoir. Right now I'm having a hard time getting the bolt to go back that holds the ground to the back of the distributor. Once I do that we will see if it starts.
