Won't start Stops running when warm will not start till cold

    I think it is a fuel problem and so does my Mech. I would like to think I could fix it with out going in to the tank.



    Replace filter, check ecv, replaced starter,



    It is not constant just when it is warm outside. And it knows when it is at the Mech, because it runs smooth when he lays hands on it. Running the fuel low is risky but a full tank is hard to handle. So it will be a pump in the future. I know a guy who has been through 4 fuel pumps and still has trouble also. A $600 gamble!

Need more info. Do you know if it is losing fire or fuel? This will help solve it better. Sounds like a sensor is overheating and cutting out though. Any check engine lights?

2002 Ford Mustang GT, CAR STARTS UP FINE WHEN COLD. Hard to start when warm No Check Engine lights come on.


Think about how the vehicle is acting. Starts fine when cold, hard to start when warm. In these computer operated systems, the computer runs everything. Starts fine when cold: the computer has the engine in cold start mode putting more fuel in till it warms up. Temperature sending unit in the manifold sends a message to the computer telling it to stop the cold start mode and it stops dumping excess fuel into the cylinders and it runs fine. IF, mind you, IF the temperature sending unit is faulty, it's not telling the computer to stop the cold start mode and is flooding the engine with fuel cause it's sill in cold start mode. This is my take away on your situation and the temp sending unit is something to check to be sure it's functional. Check it out. I hope this WAS the answer to your problem my friend. It's typical. Luck to'ya Bro.

Whining noise when extreme cold days, that goes away when my 2005 Mariner warms up. Seems to come and go until the car warms up.


Alternators can sometimes whine when start up on a cold morning, they run on full load till they get the battery back up to full charge. When the whining stops, switch on electrical equipment (Headlights, fan full boost, heated rear window) if the whining starts again its the alternator.

Runs fine when cold, not when warm though


The next time it won't start check the fuel pressure you should have 48-55 psi with key on and engine off.
