Question Asked: 

I have a 1995 ford Taurus which broke down a few weeks ago. I have owned this auto for three months has run fine. On a 65 degree day it will only try to start maybe even turn over, but will not run. On a 35 to 40 degree day will start and run for 30 seconds tops, in this time you can rev engine up but still hint a small hesitation, loses power quickly starts to choke up or just starts to die and shuts off. You can try to start it again only tries. I smelled the exhaust and is really rich, but doesn't smell loaded like raw gasoline, just not clean. I put fuel filter on seem to have fuel flow and pressure, did change out fuel pressure regulator didn't change. I do disconnect battery for EEC reset. I have tried to start it with the MAF, and the two other sensors on the throttle body, not all at one time, but the car doesn't start. I disconnected the sensor that is inline with PVC EGR which this sensor is vacuum and electric. Could it possibly be the cold allows the exhaust to be cold and i the 25seconds warm the exhaust up and o2 sensors be defective and not allowing the engine to run. Does the warm day have any reliance?? and does the warming of the exhaust have any relevance?? or do you have any information to help- find a remedy for this situation sensors, relay, distributor, exhaust?? please help if you ca give me a professional diagnosis. This car doesn't give a code, but does that mean a scanner won't work?? do I get some one to come with a snap on diagnostic machine?? Thank You, Larry & Crystal Baker :(
