My problem is the number 4 cylinder is dead. I have swapped spark plugs and wires and coil. I swapped number 1 injector with number 4 all with no change. I used a noid light and checked the number 4 injector circuit and it pulses nice and strong. compression test 155-153 across all 4 cylinders.I also pulled the valve cover and all the cam lobes look good and all the rockers and lifters seem to be ok when the engine is turned over. I have no CEL code. At a loss dont know what else to look at.

 

You need three things. Air, gas, and spark. From your tests you seem to be getting what you need. Are you entirely sure that the 4th cyl is not firing? What makes you say it isn't if you aren't getting a CEL

 

I fixed it. The intake gasket was actually missing a piece about an inch long on the bottom. I replaced the gasket and all is well.

 

Glad to hear it! Have fun, be safe!
