Default Looking for XJS Specs

ive been trying to find some more info about this car and have had very little luck. does anyone have a link or a site that gives the specs (performance and/or stuff like whether or not it has limited slip, general maintenance info like how much oil this thing takes)

thank you


Jeff

I don't think slow cranking would have anything to do with spark. Have you checked the starter?

To check sparg, pull a spark plug and check like any other car. Don't zap yourself. That never feels good.

If the starter is turning slowly, it might be due to a bad ground between the engine and the frame. Try running an auxillary ground.

i tried running arother ground wire and its doing the same thing. i think the problem is the main battery in the car is long gone, and will not charge, so im trying to jump start the car and i dont think the porsches alternator is strong enough to do it. i need to go buy a real battery and be done with it
