Issue's with truck wanting to start.

MellisaP. · Dec 16, 2011

1999 dodge ram 1500 V8 5.9L over 200k miles on it. I had my cat. replaced about a year ago, ever since then I have been having issue's with it wanting to die if it idle's to long and I will hear a hissing noise like a vaccum hose's is off (have looked at them and they all look good and tight) and a high fuel smell. Today it flat out refuse to start I had a "No buS" apper where my odometer read's. So I turned the key to the on position and after letting it sit for a min .my gas gauge and my voltage meater was reading again. (like it reset or something) So I tried to start it. It started but wont stay started till about a mile of driveing then I can let off the gas and not worrie about it dieing. unless I am waiting at a light to long. Also the past week I have been having my odometer go down to zero then back to where it supposed to be, or jumping all the way to 120. also have had the abs and brake light's come on while this happen's. (not every time but has started the past few day's) I have replaced my fuel pump and fuel filter since it is built into the pump! I have done the spark plug's and wire's, as I mentioned above had the cat replaced. I have cleaned my injector's with seafoam. I am getting ready to replace my battery cable's and manually clean the injector's. Oh and I have notice that my light's will get bright and then go back. Any help would be nice as I am about at my last straw.

Welcome to the forum. Sounds like it could possibly be a injector, as you mentioned the fuel smell.

MellisaP. · Dec 16, 2011

you think it could be bad and need's replace or just cleaned really good ?

Welcome to RF. I could be wrong but it sounds like you could also have an electrical issue

Welcome to RF...

I had a "No buS" apper where my odometer read's.

Now I need you to check for error codes I'm sure there is going to be one. As for the NO BUS message that is a CCD network error. CCD network problems are a bit tricky to track down but I've a got a write up that might help out a bit... Just ignore the Cummins ECM in the wiring diagram.

Hello...
I hoipe you've figured out your issues, but I thought I'd add a couple suggestions.
If you've replaced your fuel pump module, perhaps you have a creacked or lose Evap hose. That is one possibility on your gas odor. Many times cracks are on the back side of hoses or pipe nipples and cannot be seen by casual inspection. I've been fooled myself.

If the "sucking sound/fuel odor" is coming from the engine compartment, inspect the small hose and plastic line to your MAP sensor on your throttle body.I had an issue with this last summer! BTW everything looked good but the cracks were all on the bottom of the hose and could not be detected until I removed it for inspection.
There is also a voltage test you can run on your MAP sensor, but one of the symptoms is a fuel odor .

I haven't had the No buss problem but had a headlight issue untill I removed all my ground wires and cleaned them. There are at least 3 diferent ground harnesses, one set up by the fire wall and two down low by the battery tray. These get attacked by acid fumes from your battery and can get corroded. One of the looms goes to your front lighting, Once youve cleaned eveything all shiny including the stud mount on the fender, put it back together and paint cover with thick grease to help slow the next cleaning.

Hope you find your problem and post your solution!

Welcome. And good luck

I checked for code's and the only thing that came up was the CAT, O2S, and HTR were flashing. I called up the guy who put in my cat and he said he is going to look at it. The next day after I posted this the truck started fine. Also the high gas smell seems like it come's from the exhaust. Thank you all I will find out after Christmas if I just got a bad Cat. Hope everyone's holiday's are good.

This is caused by a bad PCM. search auto computer exchange and you can give them info and swap out for one. I found that if you get it through their ebay store then it is cheaper and get free shipping and lifetime warranty. I know this is issue because my '99 Durango with a 5.2L has the exact same issue and I did a lot of searching to find the answer.

Evidently the boards of the PCM warp and start to make a bad connection that then causes the "no bus" error. You can try electronics cleaner on the connections and see if it helps but it is only a temp fix anyway.

Oh yeah it will not throw a code for this issue.
