Funny I don't remember ending that last sentence with the word period, how freaking weird is that. I swear if someone talks to me while I type I start typing what they say, Musta been thinking period as in end of sentence & typed it out /ubbthreads/images/graemlins/blush.gif /ubbthreads/images/graemlins/rofl.gif

Anyway, do you have any codes stored in the system?

After a quick reread of your posts I'm thinking the failure to energise the fuel pump or even a bad isc driver could cause the light to stay on. You getting any actual issue or just the weirdo light thing?

no codes pop up, just the isc doesnt power on, and the fuel pump doesnt power on, so i tapped the 12v mpi relay to the fuel pump relay wire, and it works now.......

you know what, I havent really checked it out again, I know I energized the pump, but maybe its still tossing a code? What If there is no code, then what is it thats keeping the CEL on?

You should be able to either fix yours or get it fixed inexpensively. Good luck. I hope your traces aren't all buggered up!
