Problem just hit out of the blue....engine will crank but will not start.

I can hear the fuel pump operating on every cycle. If the car sits for more than 24 hours, it SOMETIMES starts on its own, but usually not.

Engine will start on ether, and will idle nicely for just about 1 minute before stumbling and then dying. Any attempt to touch the throttle during the "nice idle" time kills it immediately. Check engine light remains on, but I do not have a code reader....

I changed the fuel filter, but problem remains.

Car is a 2000 LX with only 44,000 miles on it. Always maintained well by a dealer until I inherited it.

All help appreciated. Thanks.

I'd say the best place to start would be to get a code reader or find a friend who already has one. You can get them for a fair price online, and you wouldn't just be throwing parts at it and hoping for the best. If you lived close to me, I'd bring mine by.

A cheapo code reader is about $30 on sale. Well worth it even if you only use it once.

Full scan tool to check fuel pressure would be nice, about 3 times that price if you have to buy one. They can save more in avoiding false guesses than they cost in just one repair though.

Could be fuel pump working but very weak..................ran into that on a Tempo last month.

Similar situation with mine late last year. Out of nowhere, it began to idle horribly and eventually shut off. I managed to get it started and to the shop. No check engine light came on and the shop couldn't find anything wrong with it.

After this occurrence, I found this website: www.safercar.gov I clicked on complaints and plugged in 2009 Ford Focus. Pages and pages of complaints. Makes me wonder if I should get rid of mine before something happens.

Now that it's getting warmer, my door locks are not working again. Driver side works, but the rest of them won't. Key chain doesn't work properly either. So now I have to walk around the car to verify that they are locked.

Sure hope airplanes don't behave like this with all this fly by wire technology.

P1237

Code reader only threw one code ... P1237 Fuel Pump Secondary Circuit (Fuel Pump Driver Module).

Checked the ground on this piece under the back seat and made it good. Still won't run.

May I assume this means I need to buy a new module?

Thanks.

Look here, stickie thread from the top of the page, to find the exact DTC listing:http://www.focusfanatics.com/forum/...rd-focus-technical-chat-stickied-threads.html

From that, you can see that the fuel pump or it's wiring isn't working (circuit from FPDM through fuel pump issue).

FPDM is working, and reporting a fault.
