Could be the main or fuel run relay located in the compartment under the luggage rack, passenger side, main relay also, fuse for the fuel relay 8amp. Electronic Control Unit is also located there.
Could be electrical, Hook up a timing light, three leads: Power, Ground, and one that goes around the wire to #1 cyl. Turn the engine over and see if there's firing. Note: u can check all 4 spark plugs this way.
Fuse lead goes to pin 30 of the fuel relay, u can jump 30 across to 57 and check for the pumps running, if not, change-I suggest both relays, main and fuel run relays. Both pumps get their 12v DC from the fuel run relay, both should be running when you switch ignition switch to on, then a tachymetric signal is fed from the coil to the relay to keep it running.

buy a cheap manual oil pressure test gauge from a parts store, not the kind of guage you put under the dash but a tester, they come with different fittings for may app's, they are about $20, being sure of the pressure is worth that, if the pressure is ok then most likely the sending unit is defective.

I Think it's just conincidance. Sainsburys fuel is checked independantly by Trading Standards and a private company. Both turn up unanounced. Plus there is a warning in the stations if water etc. is found. This shuts of the fuel from that tank.

Possible worn spark plugs causing unduly high Voltage which cuts ECU to protect it from arcing feedback. This problem generally produced during acceleration. Car usually re-starts almost immediately. Replace plugs - clean leads should be a fix if these are the symtoms

Make sure to check the fuses, most of the time when this pump goes bad it blows the fuse, and fuses sometimes get corioded and dont make a connection take a look at the fuse box.
