A Ford Transit IV that dies right after a cold start in freezing weather is a common issue. Here are the likely causes, what to check first, and whether you can safely keep driving.
If your Ford Transit IV starts on a frigid morning and then dies after a few seconds, you're not alone. This is a classic cold-start stalling issue, and it almost always points to something that's just slightly off in the engine's fuel, air, or spark management. In my workshop, I see this most often when the engine is still in open-loop warm-up mode, where the computer relies heavily on sensor readings to keep the idle stable. Once you understand what's happening, the fix is often straightforward.
