Yes. Think it's allowing the fuel to prime. However if I do it before it used to start 1st time. Now it'll just turn... I know that the only thing that has changed has been the fuel filter change.....

Yes. Think it's a loose connector back to the fuel filter that was changed. It rud and drives fine just starting takes 5 secs or so. Guess it could be air getting into the fuel

Unless I put the key in for 5 seconds then turn the diesel engine. If I turn straight away the engine just turns. Used to start 1st time always until the fuel filter was changed. Car runs normally once started. Could it be air In the fuel?
