Car came as non start.

P1505 crash signal engine start blocked. (Dont have it infront of me but thats the jist) will get exact code later

Basically have low fuel pressure (50bar)

When i dissconnect IMV fuel pressure maxes out (1800 bar)

Did leak off just incase, zero flow on any injector.

So im thinking this code is stopping engine from starting. It will not clear.

Have no codes in SRS but tried swapping known good SRS ecu - still the same.

tried swapping Engine ECU and code came into new ECU instantly.

had a spare comms switch here with faulty indocator. Tried that as its on CAN line with SRS. No luck

Am i looking @ bsi or comms gault? Stumped by this.

thanks for help guys....
Enda
