Think Computer is fried.

[Ryan Rønning]

So I come out of work last night and hop in the truck and it wont start. The whole circuit with the electric fuel pump and everything is dead. I checked all fuses and relays (even behind the stereo) and they are good. So I am getting a SES light when I am turning over the engine. I decided to go get a scanner and run codes. I plug it in and wait for 20 minutes while it attempts to communicate with the truck it never establishes commo. So I called the place where I got the scanner thinking it was a piece. They told me that 9 times out of 10 if the scanner cant talk to the computer then it is crashed or fried or whatever they do.

What yall think?

Don't know if this will help, but I had a problem with the bowl heater shorting out. Its on the same fuse as the computer, I think the wait to start light wouldn't come on either. I unplugged the connector for the heater on the back of the bowl and have had no problems since. I'm not sure if it will work on the early 99's.

where did you get the scanner and whats the brand?

My Actron scanner makes my truck shut off lol, it connects after a while but then i hit buttons and it shuts the truck off.

[Ryan Rønning]

I got it from autozone. It was a cheapy, about $162.

[Ryan Rønning]

Cmon guys, I need to know if its the computer or not

[Jarrod B]

well thats half the prob. autozone scanners dont work on diesels besides pullin codes.

[Ryan Rønning]

Thats all I was trying to do.

[thbd77]

[Ryan Rønning]

Yes I have!
