I Tried to start my van (T6.1 150BHP Manual CXHA engine 22k miles) As soon as I put my key in the ignition the glow plug coil light came on and didn't not go out there was also an error message on MFD saying ACC error. I have had similar messages a few times over the 12 months I have owned it but as soon as I turned vehicle off by key and restarted all was fine.
the other night though the engine kept turning over but would not start. I turned the vehicle off and tried again but the glow plug amber light stayed on but the error message disappeared. After 6 attempts I gave up and got the van recovered.
It has been into a local garage who have fixed some chaffed wires - I have seen a few posts on here regarding this issue, but doing diagnostics tests while trying to start the engine it comes up on there tests as low fuel pressure.
They advised to have the pump and injectors tested. All apparently all came back as fine so it was all reinstalled. Yet it still will not start - again low fuel pressure, they have subsequently changed the fuel pressure sensor and fuel regulator that fit to the fuel rail, and again still low fuel pressure.
They are still saying they believe its the main pump at fault as fuel is coming up to it fine but its just not getting to the pressure it should from there on wards.
Any pointers would be appreciated, as im wondering if it could be a wiring issue - or engine control box issue, could these cause these symptoms, and if it was one of those would a trouble code be stored.
Cheers

Looks like I need a VW specialist on the job now.
