I’m having a weird issue with my car the last few weeks that has started to get progressively worse. I’m hoping that perhaps someone on here can shed some light on what the issue might be.
Lately when I have a little less than half a tank of fuel in my car, and it’s been sitting for a while approx 5-10 hours, the car will really struggle to start up. It turns over after the normal crank and a half but stalls out instantly. It’s not the immobilizer. To get the car started it’ll take a good few seconds of cranking to get it to turn over. It’s the same kind of cranking you get if you’re trying to clear air out of the fuel lines. The car does turn over and runs without issue once started, its just that initial start that’s giving me problem. If I shut it down right after I get it running, it’ll fire up no problem, Its only after the car has been sitting for a while does the hard start issue arise.
The lower the fuel tank gets the less time it takes for the car jump into this hard starting ‘mode’. With a full tank or anything up till half a tank, there is no issue at all. Only once the tank falls below half.
Nothing has been replaced yet, more looking for insight on what to check first. Was thinking to start at the Thermostatic T, and then move to lift pump and tandem pump. Does that make sense?
Cheers!
