fuel pump not getting 12v feed UPDATE now popping the fuse
basically coming home yday and the car just lost all power, tryed starting it again but was only cranking but not firing. anyways called AA this morning and he checked for spark which was ok, then sprayed easy start(i think) on the throttle body and it was starting while i was cranking the car and he was spraying.
so then he checked if the pump was getting a feed and it wasnt so he said this is my prob and he wernt sure which relay to check.
anyways so could it be the relay?? and can i test it the same way you test to see if it primes? and if its not the relay what else could it be?
and may sound stupid but does the pump always have a 12v feed when the cars running??
thanks in advance

fuel pump relays havea 5th terminal which it a trigger from the col (same feed as rev counter)
sounds like relay gone - check by bypassing the 2 big terms

have a look in the fuse box the fuel pump relay has an inline fuse (blue one 10a?) if this fuse has blown your car won't start so check that.
if thats ok i could be the relay itself may need soldering.
try that let us know what happens

but new problem today
right went shopping come out, start car and nothing just kept on cranking, so pulled the fuel pump relay tapped it on the dash put it back in and it started.
got onto the main road and the car just stopped so tryed the same thing as i did before but nothing anyway called the AA as i was in a dangerous area, turns out it only the fuse,
so on my way home and car cuts out again lucky i had a bag of fuse put a other 15amp fuse in and on my way again 2 mins after pop again fuse gone again so got pissed off and put a 35amp fuse in as i was 5mins away from home.
so why is it popping the fuse??
AA guy said it might be a faulty relay so gona buy a new one tomorrow, other then that he said my pump might be on its way out but try a new relay first
and is it ok to drive around with a 35amp fuse in :dontknow:
