Inertia fuel shutoff switch
The inertia fuel shutoff switch is a mechanically
operated switch, located on the bulkhead adjacent to
the washer reservoir under bonnet [hood].
The switch is normally closed and is in line with the
fuel pump. In the event of a sudden impact the switch
opens, and disconnects the electrical feed to the fuel
pump. The switch is reset by pressing down the
button.
WARNING: Check the integrity of the fuel
system before the inertia switch is reset.
Relay modules
The two multiport fuel injection relays are located in
the RH footwell area behind the ’A’ post panel. The
main relay module is energized via the ECM when the
ignition is switched on and supplies current to the
multiport fuel injection system. The fuel pump relay
module is energized by the ECM which in turn
operates the fuel pump to pressurize the fuel system.

Wow cheers guys keep it coming LOL
I have had the gas system checked out and all is ok with that, my first thought was that the injector simulator was packing in but no.
I don't have a crank sensor on the 1995 v8 3.9, but thanks for trying. At the same time, interestingly i cant find the ECU and i am beginning to think it doesn't have one as such, i have found a bunch of contactors/relays etc in the drivers side foot well, side panel. I have checked these and they seem to operate properly.

I will look for the ecm again but i have checked this area with no results.
the problem started around 5 weeks ago with the car juddering when excellerating or driving up hill, i found the springs in the dissi for the advance and retard had broken, that's when i replaced the dissi. As i do a large amount of miles i also replaced the coil, amp, ht leads etc.
The car ran really well for 2 weeks after that then this problem began last week end, suddenly, no warning lights come on, no buzzers, nothing untoward at all just suddenly dies a death. I initially thought i had replaced the amp incorrectly so i replaced it again just Saturday gone just in case but no luck. car still dies after 20 minutes of driving.
