Do you have any code's?Also i posted the diagram of the wire set up on the coil's double check that one more time and make sure there correct.Also are sure the plugs and wires are good?

No dtc fp 55psi

Have you checked your plugs and wire's?Also double check your to make sure the wire's are routed correctly.Have you ever changed your fuel filter?Your supposed to change them every 100,000 mile's.Yours could be restricted.You could also have a bad coolant temp sensor.

Plugs and wires are new. Fuel filter fairly new(about six months) watched coolant temp with scanner seems to be responding accurately to209

Only till 209?You need to watch it till the fan come's on.Did you use a temp gun to see what the actual coolant temp was compared to what the scan too said?If not then you need to do that till the fan come's on.It should within 10 degree's from what the scan tool say's to what actual coolant temp is.
