no wait to start light

[shaggie34]

ok we got a truck in the shop 2000 f-350 7.3 diesel


we have done the following

replaced the the gpr's with known working ones
swaped the pcm's since the tell the light to come on
tested voltage across the gpr's and trested the intake heater
and swapped the lights in the dash and still no wait to start light the pink wire off the opne gpr is supossed to tell the pcm and ground it out to tell the light but i don'r know we still ain't gotta light any input..??


the modis says every thing is working and it's timing out on and off like it should but just the light on the dash even swapped the dang ol dash cluster

also we just swapped all the relay in the right fenderwell and on the fuse block and nothing along with the air temp sensor

I have the same thing. The wts light has nothing to do with the gpr at all. My glow plugs are all working right just no wts light, or any of the lights in the little cluster at all! This little cluster of lights plugs into a box under the dash that I have not been able to find out what it's even called. It's not that big of a deal as everything works but it would be better if it worked like it's meant to.

found the problem


the 3 plugs left of the pcm on the fire wall in the engine bay 2 where losse after tighting the bolts up every thing was fine

Mine are not loose but I guess I could have a bad connection in one of them anyway.

It's a place to start.

It drives me nuts, it all worked in the downer truck. It's the only thing that don't work in the 76 cab. All I did was unplug it from the old truck, fish it into the 76, and plug it all back in.

Anyone know what the name of the box that the wts light, wif light, and all the other lights in that little diesel light cluster plug into??? I have been all over the web and cant find any info about it, even in Alldata.
