Car wont start, fuel pump?

Ok right at this minute I'm stranded in town. Power to car and car clicks when try to turn it over.

I don't hear the fuel pump when ignition goes on, the car wasn't running properly last night sounded as if it was misfiring, maybe not enough fuel coz pump was failing.

What test can I do to make sure it isn't wiring relays etc before I buy a pump?

This car has been off road for last 6 months and only got it onthe road last night lol

Thanks guys

take the back seat up and the small black panel, put your hand on the fuel pump, if it works you'll feel it, just recently had to change mine. people say you can hear it but i cant hear it (and no i'm not 75 )

i could always hear mine, i took the cover off, turn it over and nothing,

it could be a fail wire or something, not sure where to look,

To check the fuel pump, first check fuse 11 is OK, then pull out the fuel pump relay and link together pins 30 and 87 of its base. This should make it run continuously, even without the ignition switch being on, and will easily be heard (if it's OK), without the noise of the engine masking it.

Hit the starter with a hammer.

Or your battery is dead.

the battery was used in my golf for 5 months, then i put it back in the e30.

I might go see if i can jump start it from my dads car, but im pretty sure battery is ok, but it would rule that problem out i guess
