Hey everyone! I have a 2007 G35s that is "lady driven" lol. Moving on to why I truly decided to post, I noticed a couple months ago that my spark plug pack had a slight dampness to it compared to the others that were dry and noticed oil in the well of my spark plug. Well I decided to DIY my valve cover gasket and I replaced it myself after getting the wrong gasket 3 times I went to start my G and it is cranking but there is no start. At first it was close to fully turning over but as I keep trying, the whine it makes gets worse. I know the car needs Spark, Gas, and oxygen for it to run and start but I just replaced my sparkplugs in december, and I have gas in my tank. Any suggestions on what it is before I give up and tow it to a shop?

Did you fully seat and reconnect the coil packs properly? If not, you wont be getting spark. Also make sure you didn't mix up/cross the harnesses some how, or leave something else unplugged somewhere (like a cam angle sensor).
Is there any check engine light, or can you scan the ECU to see if there's any codes?
