2001 sable w/ 24v duratec, cold start issues

I have a 2001 Sable with the Duratec 24V motor. I have to crank it for a while before it will start when the engine is cold (meaning first start of the day or after it has set for 2 hours or so) no matter what temperature it is outside hot or a cold day it doesn't matter, but once it is started and turned off, it starts right up, but if it sits for a few hours you have to crank it again and its hard to start. No codes and it runs/drives eprfet.

I thought maybe it was in the fuel system so i'm going to replace the fuel filter and try again. I may just turn key to prime the fuel rails and see if it starts fine, if so I know its somewher ein the fuel system. Is is odd because it starts right up when it warm.

Out of curiousity, what kind of vacuum should this motor pull at cold and hot idle? I'll also search for vacuum leaks but I doubt there are any.

Any help would be greatly appreciated.

Thanks!

Dave

It may have a "fuel leak-down" problem where the fuel pressure gradually drops from either a failing fuel pump or leaking injectors. A good Ford Dealer can perform this test on the injectors with the special diagnostic tools there.

i dont know where my last reply went. If it was a fuel leakdown issue, then I should be able to turn the key and wait for fuel system to prime fully. Maybe turn key off and back on one more time, then start it and it should fire right up.

ILl try this

ok little update. after i let it sit over night and start for the first time it will start fine IF I turn the key on to prime fuel system two times. Turn key to on, wait till pump shuts off, repeat. Then start. It will start fine. What does this mean?? Do i need to replace something?

It's not bad, it's just allowing the fuel to drain back into the tank from the engine causing long crank starts unless you prime the fuel system.

It is bad. The pump contains a check valve that is supposed to hold fuel pressure for a long time. Unfortunately, you can't replace the valve seperately. If you want to live with it you can since the pump still works but it will eventually get worse and happen when the car is warm.
