The engine has been running fine but suddenly from a cold start it can take cranking the starter for about 5 secs for it to start. I hear the fuel pump come on for about 2 secs before cranking.

Along with this my daughter mentioned that when driving it the car will suddenly jerk and then it is ok. Do you think the 2 are related?

I changed the plugs and fuel filter about a month ago and the car has been running fine.

I have a scan tool so I can monitor the fuel pressure with it but some how I don't trust it. Surely if the MCU saw the fuel pressure drop while driving that it would have thrown a code.
