Help! 2005 rx-8 won't start after storing

Hello everyone.I've had my RX8 since 2006 and being in the military have had to store it multiple times. This last week I pulled it out of a 4 month storage stay. I added a couple oz of marvel mystery oil to the fuel and took out the spark plugs and added a couple oz to the engine as well and then let it sit for 3 days. As I said I have started it after storing at least 5 times before but this time it is being extremely difficult. I have a brand new battery and I'm supporting with a shop charger. I took out each spark plug and cleaned it very well. I even removed the air intake and we tried misting fuel while cranking it to shock it to start and nothing. When we check the spark on the plugs by removing and grounding them when we crank it all I get is the first spark and then nothing.



Any recommendations or your thoughts will be greatly appreciated. Thanks in advance!



p.s. I find it really odd a new member cannot post something to the troubleshooting forum for 'a little while'. I imagine troubleshooting is one of the more dominant reasons for people joining and posting to a forum such as this so it really doesn't make any sense. ( I'm sure it's to control spam, phishing etc. but it irks me).

Thanks!
