I have a 2002 Ford Ranger with a V6 4.0L engine. Periodically in cold weather, it will not start. After having this occur several times, I began to listen for the fuel pump to energize before starting. If I didn't hear it energize, it wouldn't start. After turning the key on an off several times(but not turning the engine over), it will energize the fuel pump and then it starts.
This only seems to happen in cold weather. Last winter, a mechanic swapped a couple of the relays around and it worked fine. But we never really had much cold weather after that and it started without any problems all spring, summer and fall. Now that winter is here the problem is back.
Any ideas on what the problem could be?
