Question about 1988 Jaguar XJ6
Engine is not overheating under 90 Celsius. When Jaguar dealer replaced the fuel pump in the tank I believe it was not secured properly as we can hear what sounds like something rolling around in the trunk yet there is nothing in the trunk. also The car sat for 20 years in a garage from 1988 to 2008 when we bought it with 20,000 miles however the problem did not begin before 70,000 miles in addition to fuel pump, fuel pressure regulator, and fuel filter, we have replaced the coil, rotor cap, rotor wires and spark plugs. in cool weather runs fine. Have yet to replace the return fuel line, however we wonder what else could be the culprit

Fuel pump is bad or plugged fuel filter it seems. Crack the line from the filter leading towards the engine first. If gas starts squirting out fast, you have good pressue. If not the filter is plugged or a bad pump. How old is the fuel filter by chance? If original its plugged up by now

in the boot(trunk in n america) lift out the ply cover on the spare wheel, and the wheel, between the wheel and the rear is a ply and steel filler panel, held in by screwa, unscrew these and the pump (s) is under there.

check your flowmeter, this electronic device moniters air/fuel mixture, commonly located on the inlet manifold near injectors
