I got another ecu and got it in. Still not led. Led on this one at least blinks when i turn the key off. I noticed though, as im plugging it in, the led comes on really dull for a split second. As I'm unscrewing it, the plug comes out crooked, but the light comes on with it cocked to the side with the power pins. I'm at a complete loss at this point. If anyone has any suggestions as to where I should be looking? Maybe another engine harness? it would be appreciated.
