I think I?m in deep 💩

First and foremost thank you for all this information. It?s amazing.

So when I start the car the engine fans go on, and and the vacuum pump goes on. No clicks, no start, no pumps. In the interior however everything comes on EXCEPT the Check Engine light.

I forgot if you had the ECM looked at or tested. Make sure it is the correct ECM, also make sure the MEMCAL is secure in the ECM. With key on in a normal situation the fans will not come on, if you have the ALDL jumper for codes the fans will come on

Sounds a lot like a mem-cal error. Either wrong mem-cal, not seated or damaged pin. The immediate cooling fans and ERR on the digital readout also are indicative. Didn?t read entire thread recently but have you tried a replacement known good ECM?
