I have an 1988 Jaguar VDP, I keep getting a fueling failure message. I have replaced the fuel pump and filter but, the problem still occurs. The message comes on after the car has been running for 30 min or more. HELP1

chek fuel pressure test then do a compression test on all cylinders should be at least 150- 175 psi the early engines suffered from prematually worn out nicosil coated cylinder bores but your engine is poss way after that but 1st thing comes to mind is low compression, good luck
If the engine turns over it is not likely an ignition switch. Can you hear the fuel pump kick on? Is there spark at the distributor cap? My thought leans towards either a bum fuel pump or ignition amplifier (ignition module). If you would like a manual to aid in testing, let me know.
This may be a fuel problem. You will need to gain access to the fuel pump relay or fuel pump to confirm that voltage is available to the pump when the key is in the run position. A simplier way to verify fuel is to hook a fuel pressure gauge to the shrader valve on the fuel rail if one is available.
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
I to have a 1988 Daimler 3.6 vanden plas. I would greatley appreciate if some one could let me know about any information on this model, ie; what made the vdp different from the standard daimler 3.6, production numbers and origional cost. In regards to your question, my daimler also said it had fuel failure. I put some injector cleaner in with the petrol and the warning hasnt come up since. As for the circuit 2 failure, it could be numerous things, but start with checking the fuses in the left side fuse box. It could also mean that a light bulb or other elecrical item has a broken circuit somewhere.
