Engine: D5: V70 2002 D5 - Starting issue (Slow to start)

[mattyboof]

I recently picked up what I think to be a good condtion 2002 V70 - D5 Manual, 175k miles.

It was cheap so I didnt probe to much into issues but it drove great on the test and has driven fine ever since.

Previous owner told me that he had to jump it that morning as he hadnt been started in 3 weeks and he suspects that the alarm drains the battery as it had let him down before when parked for a fortnite at the airport.

I did notice the alarm was randomly going off so I pulled the fuse. I dont care about the alarm.

The issue I am concerned about is it seems very slow to start at all times but particularly when sat overnight and cold. Im talking 2 rounds 10 seconds or so when cold and 5-7 seconds when warmed up.

I first through battery so I charged it to full, same issue.

I also thought the battery may not be delivering the required amps so I hooked it up to the charger and started.... Same issue.

I think the battery is slightly under spec'd : Its a Yusa 3000 YBX 3096 : 76ahm 680A(en)

I have no dash warnings or anything like that but when I pop a code reader on I get:

P0088 - (Powertrain) Common Rail High Pressure

P0244 - (Powertrain) Turbo charger wastegate solenoid "A" Range / Performance

I have only had a go at looking at the P0088 to see what I can do at home to help out as it seems that could be related to my starting issue. I took a look around on youtube etc and some say to change the Fuel pressure regulator (low side) so I did that... Same issue.

Others have said the fuel return hose from the injectors may be clogged. So i have taken a look in a couple of spots to clean them out they seem ok. I have also unplugged and cleaned up the connectors associated with the fuel rail but they were fine. No signs of leaks anywhere either.

Before I take this to a specialist and spend more than the car value getting it fixed is there anything else I should be taking a look at?

Once started the car drives great , pulls hard in all gears and no adverse noises or smoke or anything.

Cheers
