Thought my car was having an intermittent struggling to start problem, but i've narrowed it down to it only does it when I get below around 1/4 tank of fuel. Basically when it hasn't run in a few hours (overnight mostly) and it's on low fuel, it will splutter when i turn on the ignition and sometimes fail to start entirely. However, if I let the engine turn over a couple times, turn the key off, and then turn the ignition on again straight away it fires no problem. Kinda seems like it struggles to get fuel from the tank to the engine, but once it's "primed" it's fine. Fuel Sender / Fuel Pump issues?
Also i've been struggling with my boost being really intermittent. Sometimes it will boost fine between 3000 - 4000 rpm, nice and strong, but that's only like once or twice a day really - other than that it feels naturally aspirated. Could this have anything in common with the fault above? My car also spits fuel out the back like nothing else; am checking to see whether that is a dodgy map, but again could be linked?
