Default 4 Dead Cylinders

So my car runs like crap, and it seems as if I have all 4 cylinders on the passenger side dead, the exhaust manifold doesnt even get hot. Any clues on whats up? Im thinking maybe my timing chain skipped a link or something and Im slightly out of time. When I swapped cams it was having some issues with the timing chain tensioner on that side..

I donno too much about technical **** but have you checked the fuel rail? I heard thats one thing you usually check when stuff like that happens

I thought that could be a cause, but the way the fuel rail is set up, fuel enters on the passenger side and supplies the drivers side.

before you tear it down to see if it was the tensioner. i would check the basic stuff like spark and fuel.

keep us posted, you said it seems "as if" the whole pass side is dead. i wouldnt think that bastard would run with a whole side dead. but like jordan said check spark and fuel. i donno if you got COP ignition or two coils, if two seperate one of def dead.

also not sure how it is on fords, but when you get a catalyst damaging misfire the check engine light will flash. meaning youre getting a **** ton of gas dumped into the exhaust, therefore a spark misfire is occuring

Any codes? I had a Continental at work with a whole bank dead.. It threw codes but had no CEL. The harness for the COPs rotted the insulation off all the wires and they were all shorted to each other.

Do a compression check.

No codes, checked with my SCT, but for sure the 4 passenger cylinders arent firing. The exhaust manifold is dead cold after it runs. The drivers side exhaust is super rich too. Im trying to get as many thoughts on the subject as I can before I tear it apart. I dont think its a blown head gasket because that shouldnt make all cylinders go dead, just 1 or 2. I replaced the spark plugs and they were a little dark, but that was most likely from when I was testing the car after the cams/SC before it was dyno tuned. The COPs had the proper resistance and the fuel injectors where fine. Its has to be something that has to do with all 4 cylinders, thats why I believe it may be a cam issue. Another thought I had was it may be a problem with an O2 sensor, but that usually throws a code.
