2000 F350 CC 4X4 with a 7.3L PSD, completely stock.

When I attempt to start the truck the wait to start light on the dash does not illuminate and the truck turns over fine but will not start. All of the other lights on the dash seem to work fine.

I drove the truck, it was running fine, and then I turned it off. I went to start it a couple hours later and this problem occured. Never had any sign of trouble prior to this hapening.

Has anyone had this same problem? What caused it and how do I fix it. Any help would be appreciated.

Thanks.

check the PCM fuse.


Usually when they blow its from a shorted fuel bowl heater. unplug the heater from the bowl, replace the fues, and try again.

The fuse is not blown, I checked it?

Ant other ideas? Has this happened to anyone else? Does anyone else have any suggestions?

What fuse did you check? On the 2000 do you still have the fuse block under the hood and the dash? Check fuse 30 under the dash. It is for the PCM and Fuel heater.
There is a PCM relay also..dont know what number that is. Definately sounds PCM related. (No WTS light and no start is an indicator of that) GP system is not really related to weather you have a WTS light or not,, just a convienence so to speak.

I've diagnosed to 2000 f-350 this week and both were failed pcm but they had improperly installed chips but they had the same symptoms

 

[JimTJr]

Yea,, I started to mention if he had a chip,,or had taken one out or put one in,,, maybe he fried the PCM doing it wrong...
But no chip in the sig,,,so I assume he doesnt have one.,,,but ya know what happens when you assume.... /ubbthreads/images/graemlins/rolleyes.gif

There is no chip. It is 100% stock.

Check the Pcm Relay under the Hood. I think its #30 its listed in your F-series/Powerstroke owners manual. Mine was doing the same thing.
Hope it solves the problem.

The fuse #30 is under the dash,, the PCM RELAY is also #30 See here I think,, anyway. hehe,, I have never had to mess with the Relay,, I do KNOW that the PCM/fuel heater fuse is under the dash,,and number 30,, been there done that! LOL
My heater is still unplugged!

It's a longshot, but maybe the lightbulb in the dash burnt out.

1st scan for DTC's.

Check the PCM connections.

Then I would unplug the fuel heater and replace fuse # 30 even if it looks ok.

If no start after, Then switch the PCM relay with another one in the power management box (under hood). or a new one.

If no start, Then try a different PCM hopefully borrowed from a friend before purchase....R
