Hi all i am from Sydney Australia and have a s1 elise, and am experiencing the same problem Fuel Pump not priming. It happened when i was stuck in traffic one hot sunny day and the car just stopped on me, after several attempts trying to start eventually got it towed to a garage, the mechanic showed me the fuel filter was full of dirt and looked brown, he has checked fuses and the multi function relay unit appears to be fine, he assumes tank would be filled with this dirty dead fuel thus causing the fuel pump not to work, also the fuel cut off switch seems to be removed i cant find the damn thing anywhere. so im guessing its the fuel pump itself, i was just curious every time it happens it happens on a real hot day, why is this? has it got do to with the fuel heating up..? the car getting hot? the car has not ever overheated, so buggered if i know

thanks for your reply scuffers, the mrfu is indeed making a click, i have checked the fuse in the back also is fine, i have also changed crankshaft sensor, so im hoping there is no power going to the fuel pump or the fuel pump itself. i forgot to mention that i poured a bit of fuel through the throttle body and it started for about 5 secs then turned off, wen i took the fuel filter off and try to crank it over there is no fuel coming out of the line, isnt it suppose to spit out fuel if your tryin to start it? as for the immobiliser ill be damned if i can find that, it is working fine regardless.

Thanks for the reply, I've got the pump off, and tested on a battery it is working, can you tell me exactly which wires to check on pump, how much its supposed to be reading (voltage) and what I can do to prevent it from happening again
