Trouble with an 'ol PSD

Heck no, by the time he hooked that computer up to clear it he just wanted us out of there(probably because he realized that since he couldn't blow up that tranny he wasn't going to make any money). But I dont think that the truck was still having trouble when he took it to the shop. I wasn't there and I never thought to ask that. I kinda wish my gryphon could pull the codes on the other trucks in situations like this. They also have an '04 expy that had a fuel system problem 6 months ago.

That sucks!

Tell your Dad to stop by a dealer someday and get the recalls done on it. There is a recent recall on the Cam Sensor and one for the Cruise Control Deactivation switch. Should be an in and out thing, both are very easy to preform.

I will say that the sensors they are using for the recall are not as good as they can be, but will cure his stalling issue.

Good Luck

UPDATE:
Just talked to my mom who has also had it happen when she was hauling hay and when the engine shuts off so does ALL electrical (including the A/C and stuff) then the battery light starts blinking. I just didn't notice because it was during the day and we had the radio off.

The reason he doesn't want to take it to a shop is because of bad experiences. He drove a 6.0L PSD for the utility company and it lasted a while until something simple went out. Soon that truck was spending more time in the shop than on the street...including injectors needing to be replaced every 4-6 weeks.

We also have a family friend who took her truck in to get the cruise control recall fixed and they came up to her with over a dozen deep engine parts from HER truck in a 5 gallon bucket saying she needed to replace them. And the best part is that she didn't authorize any of that.

Yeah we dont like the shops and dealerships around here. Tomorrow he will be getting a repair manual and a code scanner and do it himself. He just wanted me to ask to make sure and I knew that at least somebody on here would know whats going on.

As everyone knows, I'm no authority on diesels, but if you have "complete electrical failure", it's going to shut down the PCM which in turn will stop all fuel delivery to the engine.

I recall reading something somewhere, maybe in my owner's manual that there is a fuel pump shutoff that is supposed to activate in case of a collision to stop flow of fuel that might cause a fire. I wonder if if simply kills the ignition circuit (which would shut off the radio and A/C)? There's some procedure to reset it if it happens accidentally, but I don't recall what it is. I would imagine diesels have a similar safety feature and maybe this is causing your problems?

It might be worthwhile to investigate this possibility.

Sorry but, that ole girl has a mechanical fuel pump, no inertia switch to be found.

Good thought though.

Hmmm, so what is a basic method of replacing that sensor? Also what is a good place to buy a replacement?

[907DAVE]

All you need to do is pull the 10mm bolt holding it in, and with a long screwdriver GENTLY pry it out. If is seems stuck try slowly twisting it to break it loose. Lube the o-ring on the new sensor with some grease or motor oil, them pop it in and you are all set.

You can find those sensors on e-bay for around $25. Get the sensor that is black or the one that is very dark purple. Gray and blue sensors are bad, but will work ok if all else fails.


Good Luck

P.S Did you get a code out of it?
