Hello, I recently purchased a 1999 F250 7.3 Turbo Diesel. For some reason my RPM gauge isn't working. All the other gauges work fine. This truck had been sitting around for about 2 years. I don't know if it's something stuck from not being run for a while. Any help will be appreciated.

 

Sorry, I posted in your old thread..

I am wondering if your truck ever had a remote start, tthe second diagram shows the wire being white/pink. Look for tape or somethng under the dash. Maybe the wire is split and not making a good contact.

 

It does have remote start. It still works.

I'll see what I can find up under there. Thank you.
