Check eng. light 1990 jag xj6 fault code 29


The 29 code, is a ECU fail test. Lots of reasons, first is you getting yourself a new battery. Put it in and see if the 29 come up again. First things first.

The 1990 XJ6 has been sitting for the last 2 years and now won't start. The engine turns over fine. The dash gages don't seem to operate. I filled the gas tank with 5 gallons of premium gas. HELP!!!


I wish I could give you an instant fix, but I can't. Do you have spark? If so then its either your fuel pump or the CPS, crank position sensor. If no spark then it could be your coil.

Had a similar problem within the last year. Either your fuel pump is failing or your fuel filter is partially blocked. Change both and drive away.

Where is the fuel pump relay on a 1990 Jaguar sovereign, also is there a way to get into the trunk with out a key and the electric lock is not working. (there is no crawl space behind back seat)


The fuel pump relay on my 1990 is located on the passenger side under the dash. You have to remove the lower interior panel to expose a number of relays there will be a color guide that tells you which relay is the one for fuel.
