burning ecus. LITERALLY. confused.

[Jimbo_Moone]

I had my sr swap up and running there for a bit, but then it just wouldnt start. I thought it was the ecu at first, so i got another. which also wouldnt start. so we went through and checked the engine wiring... this is where it got a bit silly. we plugged up the ecu, tried to crank it, and the damned ECU started smoking. of course we disconnected it, rechecked some things. regrounded everything and tried a second ECU. same result. we checked the pin out on the ECU and it's the injectors areas of the ECU that were burning up (on both) I'm relatively new to the swap, so I was wondering if anyone had had this happen before??
