Where is the best place to source an ECU for blazers?

 

Try ebay.

 

For cheap, check your local phone book for auto recyclers. I've got a Pick-N-Pull about 5 miles from my workplace. They have a money back guarantee. You buy a used part from them and it doesn't work, take it back and get your moneyback!

 

Thanks swartlkk. I did not even think about the ol' scrap yards floatin' round here in bama. I will call them tommorow. Let ya know what I find. BTW, in my previous post with the drama over the plugs, time, etc. I stated my truck made a huge back fire and that back fire caused either my cat or mufler to blow a baffle(found that out today). What are the chances, huh.
