This morning I was fixing my trailer brakes.
The blue wire was loose under the truck...
Went back in the truck to find out that I had left the ignition on for about 30 minutes...
Tried to start the truck, but no WAIT TO START light...:confused:
Engine cranks but does'nt start.?
Check all my fuses:all good
Checked my Glow plug relay: does'nt work, tested it by removing the two small wires and jumping them, now it's cliking.
What do you guys think?
truck is a 99 dualie crew cab
thanks!

Try jump starting the truck. The batteries maybe weak from leaving the key on for so long.

It is not about the speed of the engine cranking. It is about the pcm having power. If the pcm does not have at least 10.5 volts during cranking it will not work.

When you checked the fuses did you check the ones under the hood as well.

Where was the blue wire damaged? Physical location is what I mean. Near the transfer case, near the fuel pump? I am trying to see if yo maybe shorted it against the fuel pump or bumped a wire that came off the fuel pump.

When you turn the key on, do you hear a humming noise under the driver seat area? It should stay on for about 20seconds and then shut off.

Just rechecked after charging the batteries:
Still no WTS light, and no start:confused:
The wire was damaged right under the rear bumper; somebody tapped another trailer plug in it and did'nt do a really good job.
I don't ear any humming noise when I turn the key on...
I hope it's not the PCM

The blue wire has nothing to do with the PCM. It does sound like a PCM problem though......

Do you have a chip in the truck? If so, I would take it out and see what happens.

No I don't have any chip...
Is it possible that because I left the ignition on too long, I fried the glow plugs?
They are suppose to shut down after a while, no?
In the owner's manual, they say that if you leave the ignition for more than 2 minutes, you have to take the key out,and tried it again, to reset the Glow plugs, which I did, but nothing happens

Just found the problem,:banging:
The diode in the fuse box was shot, I had between 400-1200 ohms
A new one is around 600 ohms steady.
Just drove 35 miles to get one because the nearest dealer did'nt have any
Plugged it and it's running now!:woot:
I keep a spare one...just in case,
