Dodge 2005 - 2500 Diesel

[Diamondpilot]

Truck is still dead after a day of fussing with it.


We checked the numbers on all the sockets in the fuse box and the fuse relay is reading one 'prong' at 12 and the other at 6 - all the other fuses are reading properly at 12.

Went and got at the local parts store a check engine code reader and it only gave an error message that it wouldn't speak to the computer and read the codes. So even tho it seems like there is a code dinging across the dash, no clue what it is. (chimes three times, then the gas light comes on and the check engine light --- all come on a few seconds after the engine is turned "on" (but not on as in engine rotating).

Per suggestion we sprayed lightly ether/starter fluid into the air intake while 'rotating' the engine. It did attempt to start up, but choked immediately back out did not stay running. This is the puzzling part what would be causing it to choke back out - don't know if it's an electrical issue at this point or a gas pumps issue.

Currently testing all the grounds along the frame and will report back findings.

Any suggestions appreciated as time is running out have to use it next week...

I am sure its electrical some how. It may be the electrics are not allowing it to get fuel but its time to have it towed to the dealer. It should run on starting fluid. All a diesel needs to run is the engine rotating and fuel, which you had. Get it to the dealer before you end up costing yourself more money.

I'd guess its not getting fuel, but because of an electrical problem. It ran for a little bit because its was running on ether, but once that burned out of it, it died.

ok i am 99 precent sure it has to do with the electrical on your injection pump or your lift pump in the tank you will have to drop your fuel tank and pull the lift pump out and test it on your bench it sould be pulling from 5 to 12 pounds of vacume. hook your lift pump up to 12 volts and put a vacume gage on the end of the pump to get your reading.if it is less than 5 its time for a new lift pump if its good its time to move on to your injection pump check all the wireing on the injection pump very very carefully and trace it back to your fuse box.

I would be careful using ether it will blow your motor up in just a few seconds.

You have some kind of electrical problem. I don't know why you are only reading 6 volts on one prong in the fuse box. I don't know of anything on the truck the drops the voltage down from 12 volts to 6 volts. Todays vehicles are designed to operate on 12 volts not 6. If you had not already had the batteries checked I would say you had 3 bad cells in the batteries, but you said you had them checked.

Get the electrical problem fixed and you should be good to go. I would not start looking at mechanical problems until the electrical problem is fixed. Meaning I would not replace any parts unless you are 100% sure that is the problem. There was a man on another site that was quoted by the dealer as needing 2 control moduels at the tune of like 1400 DOLLARS. It wound up being a broke wire and nothing else.

I thought the ether was a bad idea also. I have heard of it exploding when it hits the grid heaters. JC

unplug your glow plugs and spray either like there is no tommorow it will not hurt anything as long as the glow plugs are unpluged if they are pluged in a small shot will not hurt anything up here in northern canada we use either like its going out of style we have to when it -50 6 months out of the year

I still say its time to let the experts work on it. Have it towed in and diagnosed properly before you tear up your $45,000 truck.

If you have a check engine light then there is a way to read the code with no special tools at all on a Chrysler with digital odometer.

"The Key Trick"
Get in the truck and close all the doors, with the truck off, put the key in the ignition and cycle it from the OFF position like this: ON-OFF-ON-OFF-ON. Do not start the truck, just turn the key to the ON position. When you are at the final ON position of the cycle leave it ON and the code will pop up in the digital odometer readout. EX: P0441, you can push the trip reset button to cycle through the codes if there are more. You can also hold trip button to reset the codes.

If in doubt, take it to the dealer, they can diagnose it properly. There's no sense in screwing up such a high priced vehicle with no gain to you.



Just for the record, the 5.9 doesn't have glow plugs, it has grid heaters in the intake manifold.
