Looks like a trip to the scrappers, i used to have a few sri's, do you know if they are the same type?
When i was starting the car, there was no whirring from the pump, so im pretty sure thats it, i bypassed the relay as well so the pump would pump without the engine turning over, again it just clunked, do they just seize up or something????
Its been hesitating for a week now, so im wondering if that was the start of the end!!!!!!!!!!!!
I havent done this myself - but apprently you can put your hand to it to feel it working.
You could get a can of fuel and some spare hose and 'see' it pumping or not - depends where the pump is as to how easy that is.
The polarity was right, glad to hear the pump pretty much widespread, i was imagining ringing a scrappers and them saying "Ooooooo, Gsi, haha no chance mate, sounds pricey" thanks for that, infact i think i have a couple in the depths of ny shed, cool.
