truck cranking no start, no bus,wait to start light stay on very dim.

I have been chasing this no bus issue and as soon i unplug ecm everything comes back to normal no abs and gauges start back working, so i decided to take ecm off and was a ratling noise comming from the inside i oppened an one of those capacitor came unsoldier so i soldier back put ecm back and no work!

still shows no bus wait to start light dim and no gauges working so I decided to send ecm to Auto Computer Specialist and they told me my ecm was fried no fixing so i need a new one they want 1599 since my ecm can not be repaired does not count as core.

I found a cheaper one somewhere else,  plug that thing and bam... same thing no bus and nothing working wait to start light stays on very dim.

I realy want my truck back but i dont want to just throw money at it and become a money pit.

Your help is appreciated.

W-T ground wire mod you got to verify you have good ground and good 12V getting to the ECM.
