Intermittent Cold start issue
« on: October 18, 2023, 07:31:59 pm »
Been having intermittent issues with cold starts lately. Issue only happens on cold start if the csr has been running it will start up with no issues. I've taken a video of the cold start, please see the link below:

So far I've replaced:
- Coils and spark plugs
- Fuel filter
- 4x injectors
- battery
- cam follower
- cleaned MAF and IAT sensors

Scaned the car which shows no fault codes.

Car has had a inlet clean and has a stage 1 map.

Lift pump or HPFP not building pressure quickly enough.
