2002 mdx cranks but wont turn

hello all this is my first post so be nice

my MDX was completely fine I'm more then moderate on fixing my acura. I do all my own work and services on my vehiclea. however I came to a wall here. my ignition switch was going bad and would randomly turn off on road and with a minor flick of the key the engine would be back on and I can press the gas and go. but now it was getting worse so I bought a Import Direct Ignition Lock And Cylinder Switch Part #: 18-0787 Line: IDI from OREILLYS. not the best but it will do for me as of now, so I took all the proper steps to take apart my cylinder and housing unit with the old ignition switch and replace with new one and all the works it came with. AND NOW the dam engine wont start after I connected everything back ( battery and plugs etc) I looked up everything possible to what the issue is and I can't find a answer. what gives the engine cranks and I have a new battery installed and no turn! the truck started flawless before I changed the entire ignition switch and cylinder and have new keys with it. the relay is still good as I pulled that out to check and all the wires and harness are connected

any one please give all advice I'm in need to fix this fast. I HAVE A 2002 MDX
