I have a 2001 Ranger. 4cyl, 5 speed, Check Engine light on , when I plug my code reader in it says it can not make contact with thtruck. Reader works fine on all others so it is ok. What can cause this problem ? Thanks
 
I've seen this before on an explorer we were going to buy used- and didn't buy it because of this problem. The only other one that did it was a mazda that didn't run- it turned out to be a blown PCM fuse. Yours is running so I wouldn't think this would be the case.

I would be checking the pins on the OBDII connector and make sure there isn't a bent pin or something. Do the same on the PCM connector.

My son said the fuse always blows when you press the lighter. He is going to put in a new one today and see what happens. What does this have to do with the pcm plug?
 
All the pin appear to be fine, I check this first because I had ran into it before
