I changed the driver side motor mount and now the passenger said of the motor is not firing at all I’m not sure what to do or how to fix it. Help please

I posted for my man who is a mechanic I how ever know nothing about anything. He figured it out. It was a ground wire that was messed up. Sorry for The lack of information and the delay on lett y’all know he got it. In the future should he have a question I’ll get him to ask his self.

 

You need to post more information.

 

The year, make and model are needed and the engine size. If you jacked up the left side of the engine and tilted too hard to the right, you may have damaged something over there. Ignition wires at the starter can be effected. It is all guesswork at this time. Plus: " and now the passenger said of the motor is not firing at all" this statement makes no sense to me at all. How do you know all cylinders on the passenger side, #2, #4, #6 and #8, are not firing. This is assuming you have a GM V8 engine. I hate assuming. Stop making us guess and post the rig info.
