1996 Isuzu Rodeo 3.2L V6 mileage: 65,000. My wife was driving her '96 Rodeo 3.2L V6 and the speedometer quit working. Oddly enough, the CHECK ENGINE light came on about 2 minutes later. When she restarted the CHECK ENGINE indicator came on immediately. I pulled the ECM fuse to reset the computer and drove the car for a few minutes. The CHECK ENGINE light did not come on, but the speedometer still doesn't work. Should I be thinking loose connection (already looked and didn't find any), faulty ECM, or the unlikely coincidence of speedometer failure combined with failure of another component that would trigger CHECK ENGINE?

Your computer needs information from the speedometer signal to properly manage the engine. When your speedometer quite working, the check engine light did what it was supposed to do. You need to get the speedometer working again and then clear the codes from the computer.
