I just joined and need help with my 2004 taurus. SES 3.0 24 valve.
I have 174K miles on it. I have an issue that started about a month ago, engine turns over just fine but wont start. If I disconnect the negative battery cable and reconnect it starts right up. Is this a computer problem? anyone else have this happen?

is their a check engine light on? if it is please go to the auto parts store and get the codes read usually free of cost and let us know what the codes are. Have you changed the fuel filter is the car up on all maintenance ? how dose the car run other wise?
Next time you try to start it, watch the Check Engine light. The light should light up as soon as you turn the key. But if the crankshaft position sensor is sending good information, the Check Engine light should turn off during cranking. If the light stays on, test the sensor.
Could also be a bad battery or a loose connection. I would have the battery tested to make sure.
Check that battery!

The Only Dumb Question Is The One You Didn't Ask!
check engine light is fine no bad codes had that checked already. car runs great. turns over just fine but every once in a while will not fire unless I disconnect battery and reconnect. battery has also been checked. could my computer be going bad
Anything is possible But i tend to start simple.Have you checked to see if your getting spark? I have a vulcan and plug wires its easy for me to check for spark. Not sure about your coil on plug set up. im sure someone here has a trick to do so. im leaning toward a fueling issue if your fuel filter is not stopped up. I would say it could be the fuel pump I had a 2005 Gmc Yukon drive perfict till you took it on a road trip and drove it 2 hours and the pump would over heat and shut off as if it ran out of gas and it would restart after 10 minutes and go for another 10 to 15 miles and do the same thing till you parked it over night than you could go 2 hours once agine
Get the battery checked. Fords are known to locksmiths for being horrible to program new keys for if the battery isn't at least 90% charged, or thereabouts. I suspect your problem isn't spark or fuel, but a bad battery playing tricks with the PATS security system. When you clear the computer by disconnecting/reconnecting the battery you start the problem cycle over again. If you have more than one key (I sure hope you do!) try it/them to eliminate or confirm a bad chip in the key you're using.
Watch the THEFT light when cranking with no start and report back exactly what it it does.
