It's probably a vacuum line issue. Check all your vacuum lines and elect line connections related to the airpump.

Its not a vacuum issue, there was updated hoses way back when, but theyre no longer avail. You probobly need a new air pump and replace the metal 1 way check valve as these leak exhuast over time and burnup the inside of the pump

Thank you all so much for your help

Is this the 1 way check valve your refering to 1995 Jaguar Air Inject Check Valve :: Also any Idea where I might find it? ( have to learn somehow) I am supposed to drive 1600 mi round trip with it leaving in a few days. Will this hamper the trip or cause futher damage to the car if it turns out the air pump is BAD & needs replaced. Thanks again.
