#833 of 852 FUEL LIFT PUMP RELAY DRIVER CIRCUIT

FUEL LIFT PUMP RELAY DRIVER CIRCUIT
Nov 01, 2011 (9:31 am)
Had a 2005 Cummins shipped to me in Haiti. When we finally got it out of customs it would not start. Ran fine stateside. I'm not a mechanic but want to try and steer the Haitian mechanics in the right direction (and keep them from tearing the engine apart as they wanted to do). Truck was drained in Miami of fuel.
The fuel pump relay is not getting power. A mechanic stateside sent me a six page diagnostic test that I don't understand. Where's the FUEL LIFT PUMP RELAY DRIVER CIRCUIT? Fuel pump works.
Other problems - dash gauges do not work, and ABS pump runs all the time so we removed that fuse for now. Could it all be related?
Sure do appreciate any help. Our old truck hit a horse a few days ago and is totaled. Driver OK. Horse not so. Without transportation.

sounds like you have an injector or two that is leaking down, slow cranking (by bat) will make it not start. i f it starts when jumped ( man tranz) and not when cranked by bat. then that sounds like the issue, I would check that out.

I just received Rock Auto's monthly newsletter; and it contains a note about a Dodge Ram diesel club; which is intended as a help aid for Cummins diesel owners. Just thought you might like to know about it:
(www.Mopar1973Man.Com) is a web site where Dodge Ram Truck owners with Cummins Turbo Diesels come to learn more about their trucks. We talk about a different type of performance, milestones and MPG. We have members with over 500K miles and one that has 1 million miles. The site has many write-ups, articles, and a lot of other “self-help” videos that take you through your most common repairs & diagnostics on your truck. Some of the videos are done by myself and then expanded on by the members as they share their experiences.
If you’ve got a diesel, want help with a problem, or are looking for other diesel fanatics to connect with – visit (www.Mopar1973Man.Com) – we welcome you to the garage!

I have a 99 ram with 5.9 Cummins that just turned over 100000 miles and suddenly my oil pressure gauge stopped working. Truck mstill runs fine and at $200 I don't want to replace sender if that's not the problem. Can anyone help with this problem. Thanks

The oil pressure sender contains a resistance element which varies its resistance according to the oil pressure it senses. There are specifications about the sensor resistance at different oil pressure levels. If you get these specifications; and then use an ohmmeter to measure the resistance across the pins of the sensor when the motor is stopped and when the motor is running; you'll be able to determine whether the sensor is defective or not. I expect you can get the specs at the website mentioned in the preceding post #836. Alternately, you can go to https://www.eautorepair.net/ and sign up for a one week unlimited online subscription to Mitchell Manuals entire professional grade database of information for your year and model truck; for $11.99. This is the most complete and accurate database in the industry; and is full of wiring diagrams, specifications, diagnostic and repair instructions. The price is an absolute steal for what you get. If it turns out that the problem is in the wiring harness or in the gauge; there will be all the details you need to test and repair it there. And if it turns out that this motor uses some newfangled type of sensor, instead of the traditional resistance element; there will be instructions about how to test it there, too.
By the way. http://www.rockauto.com sells a new oil pressure sensor for this vehicle under Standard Motor Products part #PS407, for $158.79.

Thanks for the info, I think I'll try the Mitchell Manual site first, these are the best books around, used them a lot when I was turning wrenches.
#840 of 852 Check Engine Light
Dec 31, 2011 (9:15 pm)
I have a 2005 Dodge Ram 2500 4x4 with the 5.9 Liter diesel. Today my check engine light came on and the throttle seems to be sticking when I let off the gas. Instead of the truck idling down it continues to pull through almost as if the cruise control is set. It also is running rough when I accelerate almost like its not getting enough fuel. Do I have a sensor going out or a bad fuel pump or a clogged fuel filter? Any help would be appreciated. I've never had any problems until now but I did just have the crank case seal replaced the other day. Thank you I'm the furthest thing from a mechanic
