Hi, I just acquired a 1998 XJR, complete but not running. I love working on cars but haven’t had the chance for the last few years so I bought this as a (hopefully fun) project. The body is sound and straight with no rust anywhere. The exhaust system looks great. Paint is British Racing Green and looks okay. After some compounding and a little touch up, it should look very sharp. Upgraded front brakes (Brembo with 15 inch discs). The interior color is oatmeal. Passenger and back seats look great. Driver’s seat left bolster is split although the rest of it looks serviceable. Mileage is 200k. It gives the impression of a car that was well-kept (at least until recently, as it has three different brand of tires on, none looking too great).
I started my project after seeing no fuel pressure. Both fuel pumps were dead, and the fuel filter was completely clogged. I wonder if the latter caused the former. After fuel pump pressure was restored, it still wouldn’t start. I took out the coils and plugs. Plugs are fine, NGK platinum. I really don’t know how to test the coils. Since I was already into the engine, I decided to take off the cam covers, having read about the secondary tensioner failures. Here’s my bafflement: the tensioners are the original orange plastic ones. From what I’ve read about them, it seems an impossibility that these tensioners could still be intact at 200,000 miles.
Is it possible there’s been an engine swap? Or is this just a freak occurence?
Explanations, theories and wild guesses are welcome.
