Please help help

1988 Bentley turbo r, intermittent starting problem.
So first time i drove car for 80 miles no problem. Ran like a clock .
I was about 70 miles from home and car turned over and would start and rev as long as i was turning key. Soon as i let ignition key go, car cuts out. 100% seemed like lack of fuel. . I swapped out all relays . Checked all fuses . Still wouldnt start. Got tow truck 80 miles to garage and car started as soon as unloaded.
I then replaced fuel pump, accumulator and checked all fuel lines. Because car would start for 3 seconds and die. As long as i cranked car it would run. When it ran it was like a clock.
Im now stuck on 4th floor of a multistory car park and had 3 recovery companies tell me they cant move my car.
Car tries to start for 3 seconds and dies. It has a scorpion alarm immobiliser fitted in prob 1990. When driving car it usually runs like a clock. Perfect.
But when parked . It decides not to start.
I replaced fuel pump, filter 3 weeks ago. Plus accumulator.
Car has a scorpion alarm immobiliser fitted. Could this be the problem.
Appreciate any help please
Mitch

Hi Mitch , yes the pump should run a second or two when the ignition is switched on.
Check fuse b5 ( think this is the one)

Turbo r

I don't know how old your car is,on the early model when you turn the ignition on the power goes to the fuel pump & the ignition,when you turn to start it there is power going to the starter and to a second feed to the coil to boost the power
It looks like you have no power to the coil in position 1 on the key But when you turn to position 2 it will start because the coil is getting power from the boost connection from the starter.
.
1) get a test lamp and see if you have constant power to the coil.
2) check if you have constant feed to the pump

If you put the car in reverse gear and turn the ignition on and listen for fuel pumping........then while in reverse gear turn it to starting position and see if you hear a different sound.
The fact that you can drive short distance 's makes me think you have an overheating coil,or the resistor on the coil is faulty.
You are near Tallagh auto parts and these are cheap.
You have my number

I forgot to mention that the electrical feed for the fuel pump goes from a unit at the oil switch and then the fuel pump,this will not let power go to the fuel pump if you have no oil pressure.If you loose oil pressure while driving the power cuts out to the fuel so you don't blow the engine.
