Hello I know this isn't a Silverado but maybe someone can help. I either ha have a bad ebcm or a bad ground withing the ebcm. Problem is I cannot get up to the 4 bolts to remove it. Any tips or suggestions?

Why can't you get at the 4 screws?  I haven't looked at mine in a few years, sometimes you can get at bolts from the backside and get them loose.

there's 4 torx holding it on at the top side there is very little room to find the torx fitting while cramming your hand and wench in the small space under the floor pan.

You will have to take the lines out of the block and remove the whole ABS/EBCM assembly to service the module.  Or at least get the mounting plate loose enough to lower it to access those screws.
