AMCJeepMJ Posted May 13, 2013 Share Posted May 13, 2013 I'm looking at a 1991 Jaguar XJ40 (XJ6) Sovereign with an inline six that had water enter the fuel tank that the owner attempted to start... obviously the car did not run for more than a few seconds.The fuel filler on these rigs is on the driver side between the trunk lid and the back window as per image below. The tank has been drained, but the car has been sitting two years since. Unknown if the rest of the fuel system has had the water evacuated. Any thoughts on Jaguar fuel systems and how to get this rig running/driving? This is a pre-Ford Jag. Link to comment Share on other sites More sharing options...
jimoshel Posted May 13, 2013 Share Posted May 13, 2013 Drain, flush the fuel system, tank, lines, pump, filters, Remove spark plugs, spin the engine over a couple times, replace plugs, add a couple gallons fresh gas and try it. Link to comment Share on other sites More sharing options...

Spin by hand, or crank it over? Crank. Use the starter. Keep a eye on the plug holes and see if anything comes out. About 30 seconds should be good. Hold a finger over the plug holes. Check for a dead cylinder. If water made it into the engine the rings might be rusted. Also a squirt of oil into each cylinder wouldn't hurt. And ditto on the dry gas.

AMCJeepMJ Posted May 15, 2013 Author Share Posted May 15, 2013 So I finally got a chance to get a good look at the rig in bright daylight, and saw rust on the front subframe. I know these Jags like to trap water and cause the hollow subframe to rust from the inside out, and while looking over the rest of the underside, the rear independent suspension crossbeam had rust all over it, more than just surface... maybe from flood or was a rust belt car. This rig is a 'pass', but thanks for the advice on getting it running, everyone. :) Link to comment Share on other sites More sharing options...
