Griff not starting after lay up
Discussion
Hi looking for some advice please I have looked through the forums and have an idea but would like a sanity check please !
My 97 500 Griff not starting after lay up, I've not been well recently so its sat unused for some time, being started occasionally. The problem I have is the fuel pump is not priming, when I push the alarm button (original Meta) after turning on the ignition the fuel pump would prime and I could start it.... but not anymore I can hear a faint click from behind the dash and shortly after another from the passenger footwell it turns over but does not fire.
I am thinking it may be a fuel pump fault? it has always whined a bit.
I don't know if this has any bearing on the problem but the alarm has recently been making strange faint beeping noises when locking and unlocking, this has now stopped.
I want to get it back on the road but need it to run to get it in for MOT/service.

Hi Guys,
Thanks for the quick replies, the battery has been on the optimate so has never gone flat, its started fine two weeks ago
The immobilser on mine cuts the starter and the fuel pump and as the it turns over I am not sure that's the issue?
I am pretty sure the fuel pump relay is activating, I need to get it out of the garage to investigate more, hopefully I will have some time tomorrow evening and a one on my sons around to help with motive power to get it out.

I have changed both relays (correct OEM Bosch ) and both are working, both click once then the fuel pump one (blue socket)clicks again but still no fuel pump priming.
I have put my voltmeter on the live output side of the relays (pin 30) and there is no power getting to the contacts, I am a bit stumped as what to do next? any ideas appreciated.
I have reset the alarm by removing the battery for a couple of mins and then re-connect but still the same

I have the relays operating as they should so the ECU is sending out the correct signals but I have no power to the normally open contacts on both relays so there is no power to the inertia switch and therefore the pump.
I guess my question is where does the live supply for the pump come from ? and is there a fuse inline. I looks like the supply comes from the back of the ignition switch but there are so many different wiring diagrams I am not sure of that.

Thanks for the tips, I will get another chance to look at it at the weekend.
Blitz,
Is the main relay you speak about on the fuse board or is it one of the two dangling in the footwell ? I have power to those relay coils but appear to have no supply to the normally open contact on blue connector relay and the black one.

Thanks Guys,
I have some things to try now, but its sooo hot I just can't face it tonight, I am a bit too old to crawl about in the footwell of a TVR.
I will have another go after the big storm they are predicting for tomorrow and report back, I really don't want to get Bespoke to recover it if I can help it, I just don't want to give up as I have some electrical knowledge(ONC electronic engineering )and if its something silly i will feel daft.

I managed to have another go at the Griff today, I now have 12V at the fuel pump relay (blue socket pin 87) when I push the key fob, but still no fuel pump.
I checked the connections at the pump end and in the passenger B post and all seem ok but but I need to jack it up for a proper test though.
I have remembered the last few times I did start it the fuel pump did sound like it was groaning a bit and its allways been fairly noisy so I am thinking that the pump is knackered, Clever Trevor sell them for £108 plus vat so I think I will order an OEM one from them, unless there is a cheaper option?
