What year, what service number ECM?

From his other threads, it's a 89.

From his other threads, it's a 89.

OK, odds are it's a 1227747 but, there were others. Leaving the ECM out in the sun doesn't necessarily wreck it. Leaving the cover off and the chip didn't have the sticker with its BCC 4 letter code may. The chip gets erased with UV light.

Anyway, there are guys over on gearhead-efi who can help or, he can upgrade to the EBL Flash-II and forego the chip.

"I heard..." is never reliable. Have you verified that it doesn't work?

Its indeed a 89 with the 1227747 ecm number. And thats what happend i let the ecm with the cover off. The sticker with the 4 numbers is stil readable its 1389.
Thx for replying i wil check out gearhead efi.
And no i didnt verify yet bcs the delco 60904 is broken on my ecm wich actuates the fuel pump and innjectors if i may believe the guy on youtube who replaced it on his ecm

Really apreciated al you guys help.

And what would be different if i upgrade to ebl flash-II

It saw sunlight, or you left it sitting in the sun for months and the chips started crumbling?

The very first thing to do is see if it works.
Are you familiar with the adage "If it ain't broke don't fix it"?

It just layed on the backseat of my car for 2-3 days an before that i left it uncovered in my garage for 2-3 weeks.

And yes i heard of that ill try it out on e new ecm and see if my truck wil run.

You can tune your VE and SA tables (among other stuff) and flash it, instead of "burning" your chip to modify the .bin

Ahhh now, I remember that thread. Just find another ECM (or the EBL) and send it.
