Transit connect 2005 fuel rail pressure sensor

[coolvibes]

Hello could anyone help
Driving home my transit connect 2005 just lost power, battery light came on van stalled, I pulled Into layby the van would turn over but not fire up. Why she did until I drained her battery, phoned recovery who dropped me and the van home we're I continued my investigation into said dead van.
I started by replacing the battery then the fuel filter and Finally because the computer brought up the fault code fuel rail pressure sensor. Still the van will turn over but not fire up. Fuel is getting to the plugs I checked also starts up whilst easy start is being sprayed into air intake.
It's had new injectors installed and coded by garage with warranty.
I was aware my immobiliser was centre flashing orange now it seems to be right hand side over clock symbol flashing red acts exactly how my orange light dose flashes slowly turn ignition on 3 seconds later red light goes out.
Any ideas please

It needs scanning and checking live data otherwise you'll end up guessing and throwing parts at it.

You need to check on live-data that the engine is receiving a valid crankshaft speed signal as a basis.

If you want to make some simple, visual checks, then you need to look closely at the engine harness main multi-plug at the rear, right of the engine bay as you look from the front of the van, then track the harness across to the body-side where the harness loops near the engine lifting bracket. You are looking for any sign of chafing through the harness. Then continue back to the engine, and all the way down through to the back of the common-rail pump solenoid valves at the front lefthandside of the engine, again checking for chafing near the CR pump in the small harness there.

A proper scan and check of live data will get to your answer faster than anything else.

I don't know if these instrument packs enjoy the same failure mode as the Focus instrument packs, which will give a similar symptom to the one you experienced when the van stopped? That will require attention to the instruments circuit-board to fix, if the failure is common.
