It seems like an odd way of doing it really, I've not had one fail (either that or I never noticed!)..but should have a dud pump somewhere that might have one fitted, I'll see if I can find it.

Might be an idea to try an oil pressure gauge on the engine (same 1/8" npt fittings as a Mini etc), 'just to be sure'... The fast idle solenoid won't push the throttle out on its own , it just holds it out after you've pressed the pedal, so it may be ok? The pump cold start I'm not sure about,...

Now you mention it, I have seen some that wouldn't come off on early Range Rovers...the VW part might be a useful piece of information for the parts interchange section?

Oil pressure switch (which I think you already guessed!) , easy enough to change, no need to drain oil, just be careful not to overtighten the new one and don't use thread tape on it.....

[Doctordiesel77]

According to the parts list if your car has a mechanical fuel pump the switch should be GPS126, GPS131, or GPS133, I believe that these are interchangeable with GPS190..... If your car has an electric fuel pump, parts list says switch is GPS132, GPS134, or GPS136 , I'm fairly sure that these are not...

Just checked in haynes book, it is a peg/pin to press in....

[Doctordiesel77]

The knob either unscrews, or there is a peg to press in, (I can't remember which the Maestro one is) then the back nut, whole thing then goes out the back iirc....

[Doctordiesel77]

There are at least two more, but probably not seen this post yet......

I'm not sure how much difference there is between 'normal' and 'cold start' pressure, but easy enough to wire up, the factory engine loom connects the feed to the fuel cut off solenoid to the two temp sensors, you'd only need a couple of short wires to connect the cold start to the sensor. They usually...

My R series was registered 2/8/83, so a bit more modern than yours ha ha ha!...

[Doctordiesel77]

Sounds as though it has been altered a bit... The two pin sensor in the top of thermostat housing is for fast idle, it is closed when cold, open when warm, one pin should be to ign +, other to the solenoid. The two pin one in the head, behind injector pump is for the cold start on the pump, it is open...

The oil pressure gauge is the easy one, threads are 1/8"npt, same as a classic Mini, t pieces and fittings easy to find at any Mini specialist. There are three temperature sensors, the one with only one connector is for the gauge, the two wire ones are for the fuel pump cold start and fast idle...

Glad to hear the seller is sorting it out, petrol shortage sounds a bit bad though. Up here we were only affected for a few hours on monday, when a nearby town ran out, so the residents headed over the hills to fill up here!

[Doctordiesel77]

I think I saw an engine photo on a previous listing & it was a non turbo one, as you say, never factory fitted to a Montego, so it's a bitsa!...

If you contact "Sussex Pete" who made the last new post, he'll be able to sort it out for you....

[Doctordiesel77]

They are not easy to find, but the switch can be dismantled & cleaned, if you are careful. As far as I remember the base with the contacts in is held in by plastic clips. Ease the clips back one at a time while gently pulling the two parts apart. When the clips are all clear of the sqares that they...

Is it the same as efi? if so then I have some..Are you going to Milton Keynes show on sunday? If you are, I could bring you one, if not I could post it.....
