Stalls on Cold Start
Hello everyone. New to this forum, but a veteran with Thunderbirds.
I've got a '94 Thunderbird 4.6L. When I try to crank the engine on a cold start, sometimes it will stall, sometimes it will fire right up. Once it starts, it's the smoothest engine I've ever had in a car.
I've changed air filter, pcv valve(and vaccum lines), plugs, throttle position sensor. I got a new fuel filter this morning, but haven't installed it yet. Oh yes, the pcv valve/vaccum line change was a result of a vaccum leak I found.
Also, when I goes dead, I can hear the fuel pump being engaged again. Haven't had the chance to check the fuel pressure yet. I'll do that with the filter change.
But it only does this on cold starts every morning, once the engine goes through the heat cycle, it's fine for the rest of the day.
