1995 Ford Taurus Repair Question
Mileage: 163,000 miles.
Engine cranks but won't start
Answer
Engine cranks and no start: Go to this walk thru link: http://www.2carpros.com/articles/car-cranks-but-wont-start, then let me know-
There is plenty of spark. Obviously there is compression. There is plenty of fuel pressure. I cannot remember the reading but it was sufficient. The problem is electrical. The fan is not supposed to run when the ignition switch is turned on. the fuel pump is not supposed to keep running. When these things do not happen the engine runs.
Check and test the coolant temperature sensor, check the CCRM wiring back to the computer and computer itself
OK. Will test tomorrow and get back to you. Thanks.
Sorry, I just remembered, if you pull the 50Amp fuse for the fan, the fuel pump still runs constantly and the engine does not start.
Check out the fan circuit as directed. That was a waste of time. /Having a wiring diagram without knowing the sequence of events is practically useless. Anyway, the problem has been solved. Swapped the PCM/ECU/Brain with a 1991 Taurus that I had and Viola! It worked! Admittedly the 1991 is not a perfect replacement for the 1995, the car runs a little weird. But now I can order the proper one with confidence. Hope this post helps someone. This drove me nuts!
Thanks for letting us know, and sorry we couldn't help you better with the diagnostic steps we provided.
I gave you the sequences: and computer itself, If the fuse and CCRM checks out okay-last place is the computer-Viola it is-
