I have a 2000 ram 1500 5.9 truck. I can not get it to start most of the time when I do it will run for a few min and then dies.
I have replaced the Fuel Pump, the PCM, the Throttle Position Sensor the Hall sensor, the relays for the fuel pump, Automatic Shutdown, security, the rotary cap and all fuses.
I need help please. I am lost and not sure what to do now. Will appreciate any suggestions.
This might be a long thread with a lot of suggestions so bear that in mind. It would be very helpful if you answered the questions as they are asked and keep on track.
1. Does the truck get up to operating temperature?
(i,e, how long until it doesn't want to run?)
Because if it does, I'd check the exhaust back-pressure. Feel it when you start it and as it warms up try to see if it decreases.
2. Does it have constant back-pressure?
3. Does it have a catalytic converter?
It will run for about 10 min. It does have a catalytic converter, I do have pressure. It just started throwing a no bus and CCD code also
The catalytic converter sounds like it's clogged. Tap it a couple times with something solid and listen for any type of rattle. As it heats up the palladium will expand restricting it and the truck will stall. If you hear any rattle in there it's probably broken. Rap it a few times good with a heavy hammer to break it up. It'll have to be replaced if you hear a rattle anyway. At least you'll be able to drive it.
See you didn't answer all the questions. Does the pressure decrease as it warms up?
What do you mean by a CCD code, sorry.
no the pressure does not decrease. The Catalytic converter was clogged already broke everything loose. The CCD code is for the overhead display in the truck. I have tried resetting the computer by disconnecting the negative cable to the battery for 45 min and it still will not start. Do you think it could be the crank shaft sensor.
