Taurus Won't Crank in Maintenance & Repair Posted March 12 · Report reply On 7/30/2014 at 12:10 PM, 2000repairs said: I know its a little late to reply to the original poster about this problem but for others who are having similar issues you will be surprised to find out how I solved the same problem. I was having problems with intermittent starting where the car starter would not turn over. I had the battery checked, replaced the starter, checked the fuses and the fuse box for corroison and all the other things that were suggested. It turn out to be a relay, the pcm power relay to be specific. Relay number 31 in the owners guide for a 2000 Taurus. Interestingly the same relay went again on me yesterday and my car would start but not shift out of park, after the usual checks I tried swaping the relay and guess what the car would shift and I have had no problems since. Now I just need to figure out what is causing the relay to malfunction. Thinking a short, bad ground, or pcm is on its way out. Wow....I'm having exact problem here in 2020 ...Starts when it wants. I turn key (2000 Sable) and get all power but no crank at all. Went a week no problem now it's back. HELP. PCM Power relay?
