XJR STRAIGHT 6 POOR STARTING

SENK · September 13, 2011

Hi all, as a new member to this forum I am unsure where to find whether this topic has previously been covered. It does not seem to matter whether the engine is cold or hot but the engine cranks for a long time before firing. Sometimes it may take 4 or 5 goes to get the car going. A Jaguar expert has had the car and found no fault codes. The fuel pressure readings are as expected. A new crankshaft sensor and temperature sensor has ben fitted. Cleaning various electric contacts cured the problem for a couple of weeks but then reverted to poor starting. The expert says he is stumped and does not know where to check next. Is this a common problem with this model? Any suggestions would be gratefully received. Cheers Tony

Hi Tony, Welcome, You could put this problem on the XJ part of the forum, if you say that cleaning electric contacts cures the problem, might it be suffering condensation or damp on the contacts, maybe a spray of wd40 or ask the Jag dealer

if this could be the cause, good luck.
