A carb'd 86 RRC shouldn't have one - EFI models (And I'm slightly in the dark as to what year EFI started) have a fuel cut off inertia switch in the engine bay, on the firewall near the washer bottle - it has a rubber hood on it ( I think)

G`day

If fitted with factory EFI ( flapper ) doesn`t have one .

RR 89/90 with 3.9 ( hot wire ) had them first i think .

Rover cars and Jag cars had them pre 86 with the flapper EFI .

Used to drive me nuts with the SD3500! If you ran out of fuel it would go into crash mode and you would have to tow it up 50kmh to get the fuel pump to start again:mad:.

Also located under the front passenger seat, definitely on 89 models anyway. Push the seat forward and access from the back.

failing that dud fuel pump?

G`day , pretty hard from here but ....

Does it try to fire at all ?

Does it do anything when you just hit the ignition let it rotate a little then let the key go ?

Is the battery a goody and known to be fully charged ?

When you turn the key to on can you feel/hear the fuel pump relay trip ? ( as in put one hand on the relay and turn the key with the other )

What colour is the fuel pump relay ?

Cheers

sounds like fuel pump.......


have someone turn the key to reds as you give the fuel tank a few kicks.....it may just get the fuel pump to run......

then you will know for sure........

[rangielov]

Engine does not fire, Battery ok, fuel pump is working you can hear it when ingnition is turned on, the fuel pump relay is coloured red,

ok...that eliminates fuel pump and assocaited circuitry......


what about spark......?

ignition modules can go like that......they work fine...then you switch the engine off....and they never work again........



pull one of the leads off and stick a sparkplug in it with a large gap......
sit the plug on something metal so it earths out and crank the engine over.....
see if you get a spark......


if youve got fuel......you may not be getting spark.....
you can also pull a plug or two out and see if they are wet with fuel after cranking.......

another indication of them not firing......

May seem like alot of Qs but the anserws tell alot , ta .

Do as Tony says and see if you have spark at the plugs .

If no spark at the plugs take the coil lead out of the dissy cap , remove the cap .

This bit can bite if you don`t take precautions ( insulated plyers , plastic tongs , etc ) ................ hold the coil lead end 3/5 mm off the rotor arm middle and crank the engine , if you get a spark the rotor has probably failed , crook coil or wires will give the same .

The module on yours if factory should be under the coil and the are generally less likely to fail than the later dissy mounted ones .

If you need to test this , can tell you how , slightly different to dissy mounted .

Has any work been done to the car in the last month ?

I know you`ve already answered this but are you sure the battery is fully charged , some cars are more effected than others but a half charged battery can have a big effect on how or if an EFI will start .

I know it seems like a minor thing but it`s not .
