Hello, my name is \*\*\*\*\* \*\*\*\*\* I'm sorry to hear about problem. Ignore phone call prompt and there may be short delay between replies.
Fact it doesn't run on starting fluid tells me problem is most likely no spark. Have you tested spark? Have you checked diagnostic codes? Thanks.

Check to see if pink wires to [ignition coils](/topics-ignition-coil-chevy/) have power while trying to start, if not replace the PCM relay 60 under hood. Let me know how it goes or if you run into questions, thanks.

I trashed the spark . Nothing , I don’t list a one on the 60 it’s another number and just a fuse

Did you check for power going to pink wires? I'll find you a photo of relay.
