    Do you hear the fuel pump coming on?

    Are there any codes stored in the computer?

    Is the theft light flashing?

    This could be any number of things right now. Do you have the tools to check fuel pressure? Does it have spark?

    Gunky brown in the radiator could be a blown head gasket. Might be looking for a new engine or a rebuild. Sorry man, good luck.

    Check for spark, just pull a coil and see if you're getting spark from it. Also spray some starting fluid in the intake to make sure it's not a fuel problem. A fuel pressure gauge would be nice so we know what the pressure is :)

    Two things...

    One, we still need to know if you have spark. You need fuel, spark, and compression to mechanically run the engine. Make sure you have these things present.

    Secondly, how was the alarm removed? The car should still have PATS unless it was removed from the computer. A PATS issue can allow for a crank no start condition, so it needs to be ruled out.
