99 cummins stalling when stop
Im getting a 99 cummins today and it stalls when i stop. It has a raptor lift pump and he says it has a new bosch injection pump also. He says the crank sensor is causing this. It drives fine and will sit there and idle. What would cause it to die when i am coming to a stop? We wired the lift pump where it runs constantly but still dies. After it dies it has to started with ether. If it is sitting there idleing i can turn it off and it will fire right back up.

If you had to use ether to start it ya you can have a bad Cranksensor, but do you have an Auto or manual, if you have an auto maybe you TC not unlocking?
|
Its an auto. It still does it if you put the truck in neutral when your coming to a stop.
|
Do you notice what your tachnometer says when you come to a stop, does it just drop before it stops. And does it jump or act abnormal
|
I didn't pay attention. I'm going to get it here in a few min.
|
I know of a person that had this problem and it was a plugged muffler. They straight piped it and problem solved.
|
mine was doing the same thing on my 99 dodge cummins ended up changing my TPS and fixed it
|
pull that cam sensor out and clean it then try that. i had an issue like that, crankshaft sensor was going out, put a new one in and its fine now.
|
The previous owner pulled the fuel sender out and shoved rubber lines down in it and it was sucking air
|
I had similar issue with mine and it was my torque converter staying locked up
