94 civic cx 100k miles brand new starter, battery, cables, plugs etc... Issue is the car turns over very weak if even at all. Im thinking bad ground but i cant find a picture of all the grounds i need in the engine bay. Also on top of this what else could it be? I hear the clicks and buzzes so all of the initial parts are working...

 

There is a ground right off the transmission onto the frame rail. Also another ground on the thermostat.

 

Are you sure the new battery isn't low on charge? Connectors clean and undamaged?

 

Oh yeah im positive its not the battery in any way. Replaced: Battery, Starter, Terminals & cables, Plug wires & plugs. Also checked all the main fuses for the starter and such with nothing popped or missing.

Sometimes it will start first turn but weakly, and other times i will have to turn the key several times to get it to crank. Adjusted clutch switch today. Seemed like someone replaced the clutch master and left the pedal a little out of wack. Even with this adjustment i started it 5 times in a row but weak starts.

 

Im officially confused. Jumped it and it started but the battery is brand new. Could this possibly be a bad battery ground?

 

Measure voltage between the two battery posts.
