The XJR engine cut out driving through Battle (East Sussex) High street. Just died, no apparent reason. The engine wouldnt restart and eventually the battery went flat and I had to call out a recovery vehicle.
The recovery guy got me home and did a few checks. With their powerpack the car started but ran really lumpy and wouldnt respond to the throttle.
There is a spark from HT lead to engine block when you turn it over on the starter.
So far Ive changed the distributor cap, crank position sensor, ECU, checked the rotor arm, checked fuel pressure - seems to be plenty when you crack the joint to the fuel rail, taken out the plugs - all black, cleaned them up and replaced them. Checked the injector connectors for a switching voltage on turnover, seems ok. Changed the coolant temp sensor .
Am now running out of ideas.
