Hot starting issue - Page 2

cheshired5 · Oct 3rd, 2017, 19:20

I'm an Android man so have no long term experience with ios apps.
I've used Dash Command which was alright but the version at the time didn't have high/low gauges which are essential for these tests.
Maybe it does now so worth checking on iTunes.

You'll need the WiFi version of the ELM327 dongle.
Bluetooth ones like in my video don't work with ios.

Thanks to all who have helped so far.

The reason for not starting is due to lack of fuel pressure.
Comparing the fuel rail pressure I'm seeing to that on SiRobb's videos, it doesn't look like the tank sender pump is priming the high pressure pump; when you put the ignition to position 2 I would expect to see the pressure rise a little due to the tank sender pump.
If the high pressure pump is already primed then it seems to be strong enough to draw fuel from the tank itself and the car will run quite happily.

Has anyone replaced the tank sender in a V70 ph3? Is it possible through what appears to be a small access panel under the rear seat squab?

Fairly typically I just brim filled the tank, which will make it more difficult! If I need to drain it I will borrow a peristaltic pump from work.

Many thanks,
NAD
