If the compression test fails, it could just be that someone has adjusted a valve too tight.

Make sure that all 4 cylinders are working by disconnecting the fuel injectors one at a time. The plugs should not be wet with fuel after you run the engine and turn it off. That would seem to mean that way too much fuel is going in, perhaps the pressure is too high. The little hose on the back of the fuel pressure regulator needs to be connected to the intake manifold vacuum. (There should not be any fuel in that hose, if there is, the regulator is bad).

Compression test results...

Cyl 4 Cyl 3 Cyl 2 Cyl 1
180 154 152 155

If the car "runs" for a little (like 15 seconds) and I pull the plugs out, theyre all black and # two and three were wet with gas.

Cylinders 1-3 have low compression. This could be due to engine damage or flooding. Do you have bright bluish spark at all four plugs?

I have yet to test the quality of the spark.

Ok update... Spark was good so I decided to take the motor apart and rebuild it. New rotating assembly, crank, rods, pistons, rings, honed the block and cleaned the head. New valve seals. So the motor is running good now. Problem is now, It doesent seem like the clutch is engaging. I can push the clutch in and put it in first and let the clutch out and nothing happens but if I give it gas with in in gear, the speedometer operates, I can do the same in 2nd-5th. Give it gas and the speedo works like the wheels are spinning and it sounds like the tranny is spinning but no power is getting to the wheels. Could I have a blown diff or something? The clutch seems to work ok. I can see the slave cylnder move the clutch fork when the pedal is depressed but the wheels are not moving. Any Ideas? Before now I have not been able to test to see if the car even moved (under it's own power) when I got it so I'm not sure if it's something I did taking the motor out or if it's a problem that was present before but I'm only now finding out.
