Coil pack

I am haveing some major issues with my leagcy i was forced to srive it with no coolent and it over heated like a mofo. After new water pump and a hose that split. it olds coolent now but it sprays out the cap and the low pressure resivoir. i thought i may have cracked the block or a head gasket but a compression test had all cylinders at 150(for this test i had the oil and radiator caps off). Also it has a problem now with the ignition system. I replaced the spark plug wires but i have feeling the coil pack is bad but i dont know how to test it. If anyone has any idea please let me now.

I'm at a loss of words.

First thing's first, though, a book on english would help.

Take a multimeter and check resistance levels. I don't know what they're supposed to be, but its a start in the right (or maybe wrong, I make mistakes) direction...

You can get the coolant sniffed, but you most likely do have a leak at the head/block interface.

i know i need to test the resistance of the coil but i dont know at what contacts and what the value should be. If i have a blown head gasket wouldnt it show up on a compression test? I tested all the cylinders with caps removed from my oil and coolent so if it was firing into the coolent or oil it would be more aperent. Like i said it was even in all 4 cylenders. I guess it might be possible that i blew them all and they are all still compressing the same..... I have a feeling the water pump prop is on backwards and is pumping water strait up agenst the cap. As far as the ignition problem i am getting a tiny spark so i am guessing its the coil any ideas what else it could be?

A blown head gasket may or may not show up on a compression test on our cars. But the coolant spraying out the overflow bottle seems to indicate to me that combustion gases are getting into the cooling system.

that actually sounds frighteningly (sp?) familiar to what happened on my friends 89 cougar. that ended up being a blown headgasket leading to a cracked block.
