Hi Kevin, I fitted a new crank sensor last night to rule that out.

If I'm honest I didn't know the fuel pump had it's own relay, which and where is this relay??

It's one of the 2 purple ones on the rear row of the engine bay fuse box. The one furthest from the engine, if memory serves.

Two relays next to each other, one does fuel pump, tother injectors :y

Is the the car that was awaiting recovery a while back?

Did you carry out ANY of my suggestions?

Testing fuel pump is free and easy... Whack the tank whilst the engine is cranked...

Note, if previously run dry, a weak pump will be reluctant to prime the fuel rail... Ensure tank is at least half full before trying the above test.

I have had a 3.2 cut out with a quarter tank showing on the gauge, so comment only from experience  ;)

Hiya, yes this is the same car.

I've replaced the crank sensor and I've swapped the purple relays. There's 3/4 tank of fuel in the tank so I removed the fuel hoses off the manifold and cranked her over and not one drop came out, due to this my gut feeling is fuel pump.

I've also removed the cowling from the steering column and checked the connector to ignition module as suggested But no joy.

I've had someone stand and listen/look at the engine turning over as it doesn't sound fast but I don't know if this is because of being short of fuel so I'm going to remove the timing cover and check that all the pulleys and belt are ok.

Anymore suggestions would be appreciated

Have you tried the free test to confirm the pump?

Simply slap the base of the tank whilst someone cranks it.

The slow cranking is because the battery is getting tired.

Also double check fuse 18 under the column as that has been known to stop a car dead... As MarksDTM will testify :D

Yes, I've checked every fuse and there all ok.

No I've not done the slap test as I've been working on it at night in the factory when everyone else has gone home.

Well after a week of pulling my hair out she lives !!!

I came in this morning and tried the slap test as recommended to no avail, removed crank sensor again and refitted, had one of the electricians test me the relays, removed everything to get to heck the timing belt and all ok.

So thought sod it and removed the fuel pump,  that was a pain in the arse. Stripped it down and drained, wiped it down then connected it directly to the battery, their was a hum but nothing. I'd only put in in for a couple of seconds with the help of a friend, I wanted to blow him up as well, so we put it back on and held it on. Their was a hum but nothing then all of a sudden it spat fuel everywhere that made up take connection off. Pissed myself layghting as it covered Pete then reconnected it, more fuel came out and air then started humming smoothly. Cleaned it all up and reassembled making sure everything was clean and connected properly. Crossed my fingers, turned the key and she sprang straight to life and has been running 30 minutes. I've now turned her off to leave her to cool and I will try her again later hoping she will start again.

It just looks like their was a blockage in the fuel pump, I'm going to order a new one anyway as recommended but I'm hoping that this may have cured it. I did notice some rust on the top cover but can't imagine this caused it as it's not all the way through.

Anyways thanks for everyone's help, it's been long winded but she lives and the that's the main thing, hopefully many more years motoring to come from the old girl.

Update - she doesn't live lol

I let her go cool while I put everything back together and cleaned all my tools, then when I went to turn her over she gives a quick fire then turns off again. Looks like the pump is shot so a new one is now in order and awaiting delivery.
