I still have a problem...
I had a problem where I'd be driving on the highway and all of a sudden the speedo would go to zero and then back to what ever speed it was at. The lights, radio, etc. all continued to work. When it went to zero and back you could feel the trans re-engaging. It acted as though it lost power for less than a second and then came back up. I purchased a new ecu unit from the junk yard, same numbers. The problem went away and I thought it was the ecu. Now, 5 months later, I had this happen again. It's intermittent, doesn't happen very often and leaves no codes. So -- it's tough to troubleshoot. If the crank sensor was failing, would it react this way ? I've replaced the relays, ASD and fuel pump. Anyone have any ideas or suggestions on where to start troubleshooting.
