TexasDS

I have a 2005 C240 base sedan. As soon as the first frost hit it wouldn't start. It cranks and wants to start but doesn't. When it gets warm out it starts but misfires with no codes. Plugs were worn out and right plug wires and coils had oil on them from a valve cover leak so I replaced all plugs, wires and all coils. Replaced cam and crank sensors. Still cranks and doesn't start, just sputters. Checked fuel pressure-has 52 psi when you roll the key on and doesn't lose pressure unless you let it sit for a few days which is normal. The plugs are getting full of fuel like it's not firing but I use a spark checker and the spark seems fine. It was running fine the day before it got cold which is weird. It has 132k on it. I have been a Chrysler tech for years but this thing is driving me nuts. Any help would be appreciated.
