hi, can somebody please help? i have 1978 xjs which has not been running for 12 years and can not get it going.
i have cleaned both tanks out and changed the filter in the sump tank.when i turn the engine over the pump runs but does not pump any fuel out.
is there away of bleading the pump or is it knackerd??
hope someone can help.

Hi, The pump has a non return valve incorporated, and it is possible that it is seized shut. can you blow through the pump?

Try flooding it with WD40 and see if you can free it. It is not neccessary to prime the pump.

The sump tank has a small filter on the outlet have you examined it for a blockage?

Let us know how you get on.

hi, thanks for your reply.i took the pump off tonight and got it on the bench,you can blow through it. i flooded it with wd40 and spun it over on a batterey it goes round but does not seem strong enough, it just makes a cargaling sound.the fillter on the inlet is new.
do you know if they can fail inside?
many thanks nigel.

Thats good news. I used to run a Pre HE I liked it better than my present cabriolet. It certainly gave fewer problems. regards Kels.
