need help with my 88 supra, non turbo

[rcs666]

Maybe you guys can shed some light on this situation. I bought an 88 supra last week. For way cheap. It was running, but had some obvious issues, such as needing paint, a windshield, the starter is going out (but still works after a few tries).

Now heres the issue. It ran when i bought it. It ran a liitle rought, and i was told it was due to needing new plugs and wires. So i drove it home (maybe 45 mins), and went to do the plugs. I had to pull the throttle body due to it covering 2 plugs, and cleaned it while it was off.

When i went to do the plugs though, there was probly about a good inch of what looked like oil and coolant mix on top of the plugs. When i removed the old plugs this all drained into the cylinders. I replaced the plugs and wires, reassembled everything, and fired it up. I ran it for probly 5 minutes, and it was running way better.

So after 5 minutes of running it, i shut it off to replace the clamps on a hose, and tried to start it again. Only this time it wont start. The battery is fine, it has gas, and everything is put back together correctly.

So WTF? why wont this thing start?
