Hi Jag, thanks for the reply. Managed to sync the key fob, that works fine now. but still no start.

Had a look through the manual and it looks like all dash lights are as they should be when at pre ignition setting.

I'm pretty sure when I was pumping up a flat tyre with ignition on that I could hear the fuel pump ticking (I hadn't tried to start it at that point due to the old petrol) no ticking noise now.

Can any other owners confirm whether or not I should be able to hear the pump ticking continuously?

I've found reference to which fuses/relays to check in the boot so at least I can see if I've got voltage that far.

In terms of diagnostic software, does generic stuff work or is it like my '96 Range Rover very specific/bespoke to the model?

It's a lovely motor kept in great nick so be great to bring it back to life.

I only know on my car that the pump just runs briefly at ignition on then stops.

OK if that's the case then looks like my pump is probably dead as I get nothing and the fuses are ok. Will check for volts and relay function but reading around it seems fuel pump failure is relatively common.

Looks like getting the lines off of the bottom of the tank is the fun bit!

Will keep you posted as to progress and thanks again for the help.

Will.

First, try to reset the inertia switch. Sits inside the footwell on the right side. You may have bumped something while changing the tire. Switch kicks off to shut off fuel in case the car is in an accident. See owners manual.

Hi Jim, I had read about that but thought it stopped the engine cranking, lowered the windows and stopped the central locking when tripped?

I guess anything is possible though with 90's electrics so next time I'm with the car I'll check it.

This is good info. Thought that module was by the fuel filler but all I saw was the gas cap locking mechanism. Need to verify frequency before I buy a fob.

Thanks for this info.

I pulled that area all apart and could not feel it under the fuse box, do I have to remove the fuse box to even feel it.
This is a 2001 Vanden Plas

You have to remove the fuze box. You can't miss it! Search for threads on bad rear brake lights to see pictures. Or check for posts from sparkenzap (wonder where he went?).

I look very well in the trunk and I cannot find my module. It's not under my fuse box or nowhere in my truck. Maybe ol boys are different. Do you have any other information on a picture of what yours look like? I seen them one on the internet, and I don't see that anywhere in the trunk unless my eyes are different. Thank you. Please help.

2 bolts on the left and 1 on the right need removed. The one at the top is the fob antenna that needs to be unscrewed after you get the 3 bolts removed that hold the entire assembly in place.

It says: SLM 315mhz

thank you
Two bodies have I have a 2003 XJ8 jaguar and on this vehicle? The security lock module is not under my fuse box. Is there anywhere else to look I look behind the seat under the seat back seat and took the roof down and no security lock Lottery. The reason why is because I burnt my key when I burn my trash, LOL. But yes, so I went to the junkyard and remove the key the key cylinder the computer and speed odometer, but I can't find the security lock module to change over do anyone have anywhere else in mind to look? I don't know what the difference is between my XJ8 in anyone else's but mine. Is it in the trunk of the car Thank you.
