I gave up trying this morning as it was -3 and wouldn’t keep running, battery was getting low after about the twentieth start/stall routine.
Got a VCX Nano arriving tomorrow, got me an old laptop with Win7 on Vida 2014D installed. Let’s see just how sick my car is, hope it’s not terminal 😔 |

Yes I did tap the throttle body before I started, although maybe not hard enough. It didn’t make any difference. It always starts, then stops. Like whatever checks are going on post starting suddenly decide to kill the engine. Is almost like if it gets past 3 to 5 seconds of running I know it’s going to be ok. Not much chance of starting it in these subzero temperatures so will have to wait until it warms up a bit, but once it does I will try the vacuum pipe test, cheers |

Right, now the cold weather is out of the way. More testing has been done.
However it was averaging between 15 & 25 attempts at starting per morning during the cold weather. Start/Stop rinse and repeat until it decides to run. Throttle valve has stuck on two occasions over the last month when trying to start but the unmistakable sound and smoke is not the normal problem I was having. So I’m thinking I can rule out the throttle valve. The Vida investigation however has thrown up many problems, which is making me think this is electrical. I’m actually surprised it’s running at all, there are modules showing red everywhere.

I was having starting issues although not cold related
I was getting air in the fuel lines which was causing bad starting in a morning up to the point it would not start It turned out that the fuel was draining back leaving a lot of air in the fuel line so not getting pressure The fuel pipe from which runs from the metal fuel pipe to the fuel filter was allowing air in I replaced this with a piece of fuel hose and a none return valve and I now have no air and a much better starting car |

Maybe I have a combination of air in the fuel and some electrical gremlins.
