2001 1500 5.9 Truck turns over fine. The gauges never come alive but the dash light/indicators all work. If I leave the key in the ON position, it tells me "NO BUS"

Any Ideas?

 

Actually, on further inspection, all gauges except for the fuel gauge comes up. I sprayed some starting fluid in it and it still won't start.

 

the "no buS" thing comes up when you program the truck through the OBDII port using a hypertech programer... not sure of other ones do it too like superchips etc etc....but i know the hypertech does it... makes me think you may have a bad pcm or some wires shorted near the OBDII port under the dash...

have you had the pcm programed recently ? if so was anything interupted during the program? if so i could imagine this doing it..

 

well wen i put the superchip in my 98 nouthiung came up on the display but i have the older style led one not the lcd one on the newer ones, i agree with something to do with the pcm to you have a progermer? see if you can get any codes out of it

 

Go for the easy first:
Check the fuses and disconnect the battery and clean the terminals real good.
Dad left the lights on after dropping the boat in the water(Iwas in theboat)
I had to use the boat battery when we got back and it threw a hissy fit and wouldn't start till after 3 disconnects.

 

I haven't had any programming changed and I do not use an aftermarket chip. It's completely stock. I disconnected the battery once but it made no diff. The fuel gauge never moves even though I know there is 3/4 of a tank. I took the gas cap off and put back on just in case there was a vacuum issue. It tried to start a couple of times but never would.

 

Did you check the fuses?
If you have a means, also check or take the batter to get checked under a load.
Make sure you leave the battery disconnected at least 1 minute before tring again.
Can you hear the fuel pump turn on when the ignition is turned on? How many miles are on the truck?

 

also try this ro reset the pcm

1 disconect the neg cable from bat
2 hold key to start for 30 secs
3 wate 3 min
4 hook up neg cable

sometines just unhooking the bat dosent reset the pcm because there are capasaters in the truck

 

I have almost 130,000 on it. I don't hear the fuel pump come on but I did try some starting fluid. No go. I will try holding to start for a moment when I disconnect the neg termnal. Just happened out of the blue. Up to this point, it's been a great truck.

 

Well, I found the issue. The plug to the PCM nearest the driver didn't seem to have a good connection. When I pushed on it, the fuel gauge came alive and I heard the fuel pump start. Truck started right up. Good ol' truck
