so just the other day i went and hand washed my car just like i always do, brought it back to my shop, started detailing the outside and it started up once after i washed it when i backed it out of the shop. then not even 5 min later when to start her back up and no power AT ALL to the ECU (microtech LT-8) can't get any of the lights to turn on, my worst fear is the ecu finally took a dumb on me, any suggestions on maybe a relays that could have blown that i'm over looking?? i'm gonna do a volt test this week, but figured id *** all of you, any help would be great, worst case ill need to buy another lt8 or buy a new lt-10

First make sure you have voltage to the ECU at the appropriate points. Probably water in a relay or something.

 

Check that you have 12v all the time at the RED wire.
Check that you have 12v on ignition at the PINK wire.

Check that both brown wires are grounded correctly by using a multimeter.

If all 3 check out and computer is still off, computer is cooked.

 

Ya I've already gone threw the wires. Sent the ecu in Friday for repairs. Sadly. But thanks anyways.
