I need some help!!!!
I have a 2002 crew cab 2wd hd with a allison and a 8.1 motor.I have exhaust,volant air box and a westers garage computer.This truck keeps shutting off going down the highway and will turn back on before I can pull over.Sometimes it just shuts off.When it does my battery light will come on?Then it will take a few minutes of me cycling it off and on before it will start again(actually kicks over but wont run).Sometimes when I go out to the truck to start it it will turn over but will not fire?Is this a common problem. I thought it was the computer.I called Westers and they said no.But he did say if I thought it was he would replace the computer.I actually still have my stock computer and installed it and it still does the same thing. It did it 4 times today.I afraid one day its not going to start.I need help....A friend had a similar problem and his was the fuel pump?
I had the same problem with my 8.1 it ended up being the crank sensor. Pretty common.
