Maybe somebody can help me here.
I have a problem with lumpy idle/no power just after startup. This condition lasts only for about 30 secs, but then goes away and the car drives fine after that. Now its summer (though at the moment that means that the rain is warmer) in Blitey, and I worry what it will be like as the days turn cooler.
So
I have done a little research and I will tell you what I have checked.
Individually tested top glow plugs resistance OK (all less than 1 Ohm)
Struggled to check the glow plug resistor (manifold heater) so not sure that is OK but read on.
Checked for volts being applied to the top plugs, OK. A period of 11 Volts followed by a longer period with lower volts (doesn't that mean the glow plug resistor is OK since it goes in series for the afterglow period with the top plugs).
My question is about the temperature sensor screwed into the block below the rearmost inlet manifold junction. The book talks about testing it and it shows (in the Haynes) somebody using an Ohm meter on it. However, they are having a laugh since its nigh on impossible to get at.
However
This sensor must be cabled back to the heater timer control relay in the saloon (isn't it?), so surely I should be able to measure it from there.
But
There is no circuit diagram with the timer relay (though the Haynes manual does show some fault finding/testing).
so
Does anyone have a circuit diagram for the full pre-heat system, or at least knows what the connections are for the multiplug that goes onto the timer relay. Oh and just for fun, the Haynes shows 3 variants on the timer relays.
Anyway my car is a 92 2.4 ssrx Turbo D.
Cheers... Rob.
