Hi De The sump plug would be on the base of the sump It is almost flat and requires a torqs bit to undo it once removed it will require a new o ring seal before refitting.
The filter would either be just behind the engine underneath or it may have a cassette filter at the front facing upward and will require a special low cut socket to remove the cap normally black plastic cap. (right hand side front engine where gearbox bell housing joins engine.
Hi Simon You now get a loud click! have you flattened your battery? You need to have a fully charged battery. If you suspect starter has got stuck if manual gears stick car in gear release hand brake(only on level surface) and rock car back and forth that should release the starter. If auto the only thing you can do is tap starter motor with a block of wood to see if it releases.
Coming back to the diesel issue, I am not sure which system you have fitted. If early system Lower pressure you should have like a round plunger on top of the filter this you should be able to press up and down. Keep doing this till plunger becomes to hard to press down. This will bleed system and remove all air in system. Now try starting vehicle.
Later system higher pressure no plunger, turn ignition on 8 seconds turn ign off 8 seconds (not to crank position) repeat this 5 times ignition off. Now crank to start. Hopefully it should run.
As I said make sure you battery is fully charged. Good luck
The oil light is responding to lack of oil pressure. If the level is good, you may have a problem with your oil pump or a bad oil pressure sending unit. The engine quitting and not restarting may be related to this, but not necessarily. What other details? Was there other noises before it quit? Did it quit suddenly like someone shut off the ignition or did it struggle before it died? Was there black or blue smoke from the exhaust?
If you have no power from the grid then bug zapper is not problem. If bug zapper is a corded plug in application then unplug and plug into a plug in that you know works. Check your breaker panel for a tripped breaker and reset if necessary. Or try a different appliance by plugging something that you know is operational into the same plug. If it works, there is likely an internal problem in bug zapper.
Moving the ignition switch to the START position signals the body control module (BCM) through discrete inputs from the ignition transducer that engine crank has been requested. The BCM verifies that theft is not active and sends a serial data message to the engine control module (ECM)/powertrain control module (PCM) requesting engine start. The ECM/PCM receives a 12-volt signal from the park/neutral position switch or clutch pedal start switch notifying that it is safe to start the engine. There is a splice on this circuit in the fuse block-underhood that supplies power for the starter relay coil. The starter relay coil control circuit is then grounded by the ECM/PCM closing the switch in the starter relay suppling 12 volts to the S terminal of the starter. Ground is supplied through the engine block.
