Question 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.

Any Ideas?

Re: Stalls on Cold Start

have you looked at the wires? I had similar problems and went through the same thing and still nothing was resolving it. I bought a good set of leads and it was what solved the issues.

Just a thought.

Get the multi-meter and check the voltage is constant through the alternator. The alternator on a friends 93 Mustang was giving him no end of grief on cold days the voltage was too low and internal lighting was perculiar. Changed the earthing/ backing plate on it and it ran fine.

Re: Stalls on Cold Start

Check your fuel pump it may be losing pressure over night and not having enough to ensure a successfull start the next morn. My Falcon does the same thing and this is the drama.

Just a thought.
