I've had 3 of my own socketed SMEC's go bad, all 3 were the injector drivers. Now if I knew which component it was I'd make an attempt to repair it. All 3 was the # 2 driver circuit. And yes I double checked the wiring.

That part is on the power board. Shouldn't be affected by the socket job at all...
Yes I realize that, each board lasted about a year B4 it went bad. Is there any way we could figure out what part it is thu ? I'd like to actually contact one of those companies that do rebuild these things.
Shouldn't be too hard. It's got to be one of the 5-pin drivers under the big heatsinks...
I repair boards at work (I'm know I'm no electronics guru) pretty often.
First, I check to see what's burnt, then I replace it. A schematic makes it easy to ID the the component (and it's values), just trace out the printed circuit on the board (the solder traces). If you don't have a schematic, a local HAM radio shop can be an excellent source of help and parts and finally Radio Shack (The selection isn't what it used to be, mostly cell phones and such crap).
Most of our boards have a resistor in each cicuit to take the voltage hit, to cushion the board itself.
You must have an underlying problem, due to the repeated failures. So get a couple replacement parts while you trace the cause out.
I hope this helps.

^^^ you guys got some good ideas there, if I locate a schematic on these boards it would help. I wonder if too much resistence somewhere could cause this problem. It would be an interesting experiment to wire in a seperate relay for the injectors.
I've had the power board go bad on a few different cars, I've never looked into what was bad but if it's something simple it would be worth while repairing as replacements are getting harder and harder to find.
