Ecm issues and reliability

[Recian426]

Found out today my new reman ecm is trashed. My old one had a bad processor and SIA said they can't get processors to repair them anymore. That's why I bought a reman from ARES tech only to find out today their lifetime warranty is only on the original unit not the one they send you as replacement. Needless to say I'm losing faith in the truck and ecms. The WTS won't come on, fuel pump won't run, heater grid relays stay on and no communication with a scan tool. PCM even has no communication unless you unplug the ECM. Basically similar to my original symptoms of bad processor. From first day I had this ecm it wouldn't start until I cleared the meriad of codes it had even tho it was a plug and play. one time on the highway I lost engine power for a few seconds and it came back. The last 2 weeks if truck sits more than 2 days it would crank and stall a couple times prior to starting then this. 

 

Disconnected all the 5v sensors on the engine itself, CMP, ckp, tps, coolant temp and it still didn't come back. So I read the page about ecm rebuild reliability companies and the one I got this ecm from isn't in any list there. I did the alternator diodes and alt wiring mod prior to replacement. 

 

To my main question is there anything I could have missed in diagnosis? Could I trust another reman unit seeing as SIA says processors are no longer available does that mean all the reman units will have original processors which is the main ecm failure point?
