Man! this was STUPID!

OK - so I have 94 century 3.1. It was doing the classic 'buick miss' thing at speed, so I decided to do a compression check like almost everyone suggests. Well compression was reasonable, all within 5-10% of 175 psi and each other.

Well, here's what's stupid.... I didn't disconect the hot wires from my coil pack, so I was getting arcing all along the polls (never done this before). anyway, since the compresion checked out, I put in new plugs, and replaced the wires, and when I go to start it up, low-and-behold! the thing acts like it will NEVER start again. I'm sure I fried something.

Here's my question: Is it most probably the ECM or is some other elec ignition component more likely?

And, is ther any way to directly test the ECM to see if it is blown?

Take the Ecm to Autozone and they will test it for free. Not sure about other autoparts stores.
