Would pump still run if inertia switch was knocked out ?
Would pump still run if inertia switch was knocked out ?
Would this cause my problems though becuase I can get the pump to run by turning the key after waiting a few mins
If the inertia switch was tripped, the LP pump would not run at all, as it simply cuts the earth to it. It's a mechanical switch which either makes or breaks the circuit. The inertia switch also has no impact on the supply to the coils or injectors, it simply cuts the power (earth) to the LP pump when a certain g force (inertia) is exceeded. It also does not interrupt the CAN lines for the fuel gauge sender.
Also you said your getting fuel pressure to the injectors just not past them, so looks like the LP pump is working ok.
Out of interest, when the car had a flat battery, how was it started again? Jump start? Bump start? Or has it never started since?

see post 20
what i suggest you do is
disconnect battery
remove crank sensor wiring from crank sensor
pull crank sensor loom away from engine as best you can to where it enters the engine loom
look carefully for chaffed wire /cut in braiding
good thought and possibly the answer
ie bsi busted and its gone the year 2000 too
ive also had a bsi go off because it was parked up in a damp garage for 2 weeks, i probably jump started it, but i used a proper pack so no spikes,the circuit board was a real mess

As far as I am aware after the battery went flat the car has never started. She asked a neighbour for a jump start from their car. When it did not start thats when she ring me and I got involved.
can this be repaired or is a new one.
Its the owner I feel sorry for she has spent £120 on parts I have told her it needed and it clearly didn't as it has made absolutely no difference.
