Thank you I'll grab that from the store. But one more thing. The strange thing is. what would make a scanner assign the wrong code? The mechanic told me (as I argued the firing order. That he cleared the codes and I by one went thru the front bank which would be 4-5-6. He said when he unpluged each seperate one for what we think as 4 he'd get the code 352 then he'd clear the codes again and 354 for what we think is 5. Did he have a faulty scanner or is there another problem I'm not seeing?

Since 3 is in the back. how do I check for spark when fully assembled? or how can i check with intake off?

no there wasn't any damage i could tell .. and i took the coil from 3 and placed it in 5 and it worked.

OK please help if you can. My wife has a 2007 fusion w/ 3.0 V-6 ( 63000 miles) She gets home and 2 hrs late I take her car to go drop off movies (it was raining) The car boggs down wont even go 10 mph. I go to Auto shack to borrow their scanner. (yeh engin light came on) I got the code PO353 third cylindar coil, first/secondary . I'm not up on all the computer stuff (and probably should have a professional do this but I don't have the cash. So I researched on line and went thorough the following steps. 1. I replaced that plug. (still missfiring) 2 Replaced all the plugs. (Still misfiring but not as bad about 85% of where the car should be) 3 replace coil pack for no3 Cyl. ( Still nothing) 4 switched new coil pack to another cyl to make sure it worked (Yes it did) 5 pulled connectors one at a time from front bank coils to see difference in rpm change (all three worked) 6. Was able to reach underneath intake and pull connector on number 3 coil pack (no change plugged or unplugged. still missing. cylindar order firewall 1-2-3 4-5-6 radiator I have no idea at this point nor do I have the tools to go any further. I take it to a shop and they tell me what I already know except for this They tell me the firing order is 1-3-5 2-4-6 Ok that would explain that I changed the wrong coil pack but it doesn't explain why i didn't get spack from (what I thought was number 3 coil) HELP!!!! Is my firing order right or his? He said that was the order ghe got from his scanner. but I haven't been able to fing anything online to corroborate this........
