He was afraid it would not start when help arrived. He is not mechanically inclined.

I found out that he had used Ether a couple of times when he ran out of diesel. We are in a remote mountainous area 3 hours from the nearest garage. What will starting fluid do to this engine?

Never use starting fluid !! If you use starting fluid and the grid heater is still hooked up you can you can have a pretty big explosion...and cause a fair amount of damage.

Starting fliud is not an acceptable way to get a truck going - figure out what the problem is and fix it.



Have you had a chance to crack #1 injector line and see if you have fuel? I can also step you through checking fuel pressure if you need to.

I will be picking the truck up from the shop today. The $100 per hour for diagnostics is killing me. I would like to buy the truck from my partner and get him out of it.
I will need your help when I tackle the injectors.
Thanks!

A little water can do a lot of damage, on the other hand, some of my vehicles have seen a lot of water and never missed a beat.

Here's your best bet, and one a mechanic who isn't familiar with diesel will easily overlook.

Your fuel shutoff solenoid is controlled by a relay that sits near the firewall (Don't know exactly where it should be, never seen a truck that had it in the same spot as another), its fairly low, about headlight level, so it could have burned up.

What I would do is: Use a piece of wire, some zip ties, or twine, to hold up your shutdown solenoid while you crank the engine, my guess is he's not getting fuel to the injectors because its in the "Off" position. Beyond that, I'd drain all your old fuel and make sure fresh stuff is in there, check the rest of your wiring too.

If you need any more info on where stuff is Google: "Dodge Ram Info"
It'll bring you to a page that has all sorts of good info for these trucks.

We will help you out to the best of our ability.


There is some very valuable info on these trucks here: Fritz's Dodge Ram Tech (unfortunately, its an older site so some of the links are dead) but it will give you very good general information.
