I’m getting an rpm reading with the scanner when I make it run taking away the data link wire to start it and then hook it up while running. Is this signal coming from somewhere else ?

Ok so this tells me the tone wheel is there and the oil pressure sensor must be good. Crank sensor not oil pressure

So the truck starts when you remove one data link wire tho. So will the truck run with the tone wheel broken in this situation?

Wish the chime was the only thing I was worried about lol but now that you mentioned it the chime only works for a little bit and quits could this be any of my issue as far as the no start is the box bad ? Could something have went wrong in my instrument panel and this would be the reason tach quit?

Yes wait to start light is working

The ctm is the little black box inside the cab under the dash and it’s like 2” x 3” right? If so it only has one plug on it.

I also cannot get any body codes with a scanner. Could this be a pcm issue?

Bought the truck used I’ve never had a key fob. Is there anyway of telling if security system is shutting it down. Would it tell me when I put the scanner on it? Thanks

When I unhook one data link wire and make it start and hook it back up while running there is no tach movement in the dash but scanner shows rpm’s.

Truck currently does not start I can disconnect one data link wire from vp and it will fire up and run. Currently it has dtc P0523 oil pressure sensor voltage high code.
