I have a fairly strange problem with my 2010 Jaguar XF 5.0 NA whereby occasionally it would have trouble starting (cranking with no stumbling, as if it was getting no fuel). It would randomly start up after retrying many times and would in fact, drive normally. Power is good, it will idle and no unusual sounds that I can tell when the car is up and running. However, recently the car just cut out while driving and threw the P2279 code (intake air system leak). It is now nearly impossible to start. I have done a preliminary check on the intake and nothing seems amiss...

After cranking for awhile, the engine bay actually had an explosion occur. The whole rear end of the intake manifold blew out and took the rear cross-over coolant pipe with it. After I purchased a whole intake manifold (used) and replaced all of the 8 gaskets. The coolant pipe replaced was replaced and everything is pieced back together as it was. Unfortunately the car will not start when turning it over (as it did before). I'm afraid to keep cranking it, given that the last time I did that, an explosion occurred.

I did not notice anything unusual, cracked or broken in regards to any of the breather pipes etc... but perhaps I missed something? Does anyone know if there are more common problematic area's that I should check?
