fuel pump not priming.

[Guy]

car has been sitting for a while.

new battery fitted. lots of electrical power but no sign of fuel pump priming pre-ignition

so, relay was changed about 3 years ago when the car was first purchased.

now... when this happened before the fuel pump suddenly decided to bring itself into life after an hour or so of trying and all worked tickety boo... but now it doesn't want to know.

so... erm... suggestions on a postcard please?

Hi Guy,

Check fuse 5 and relay 2 for the fuel pump.

Check the fitment to the fuse box, take it out give the contacts a  clean on both the fuse and the relay. The pump does draw a lot of current from the fuse box and these can heat up causing any solder work inside the relay to melt.
Remember the later ones on the cabby are 5 pin not 4 they have the rev limiter built in from the coil.

Check the supply to the in-tank lift pump under the rear seat. The pump may of died, usually rust in the tank blocking the inlet gauze. So an inspection of inside the tank would't go a miss. I had a new filler neck on mine but they didn't clear the tank, so it blocked up the pump and the fuel filter.
So it's worth having a look see.

cheers

i have a feeling that it may be the latter of those scenarios... my fuel filler pipe was atrocious when i first got it and we replaced it with a SS one but didn't flush the tank

Most of the time it's the fuse box connections where the relay plugs in, these can get moisture in them and the contacts inside corrode, so they are worth looking at also.
I would start with the fuse and the relay first, as they are easy to get to.
I have found just replacing an old fuse with a new one sometimes helps.
