So months later I am still having the problem. I finally decided to just take it to the Dealer. I've never taken a vehicle to the dealer so I am not sure if this is a normal thing but they wouldn't give me any codes, let me talk to the mechanic who ran the tests or anything. I had to deal with a middle man and all he would tell me is that I have a bad ECU. Does that sound right? I have tried to pull codes with a scanner and i got nothing so I am wondering if they are just saying it is the ECU because they couldn't get anything off of it. Them not letting me talk to the guy who ran the test made me suspicious. Should I be suspicious?

ok maybe ill try that first. Thank you!!

Is there a way to test the PCM? I dont want to buy a new one if there isnt anything wrong with it. I know all signs point to it but after rent, bills, and diesel(my commute is about 140 Miles/day) so I dont have much at the end of the month.

UPDATE:I took my alternator off and took it to the parts store to have it tested. Guy said it was no good only puting out 7 amps, bought a new one installed it and the truck is still doing the same thing. While I was there I bought some electric cleaner and cleaned all the plugs to the alternator and the black and white plug going to the battery, also re-applied de-electric grease. What should I try next?My batteries are fairly new about a year old. Should I have them tested?

Ok I will do that. Thank you for everything! Corey

Yeah I tested the batteries the same way shown in the video. I do believe it is my alternator because I am now seeing a big drop in voltage from my battery gauge in the truck while the truck is warming up and I believe the grid heater kicks in and out.(I read somewhere that the grid heater kicking in and out is the cause of the lights diming while the truck is warming.) When the lights dim the voltage drops almost to the bottom and when they brighten up it goes back to normal. This is all new so I am just going to get myself a new alternator... if the problem sticks around I will be back. Thank You guys for your help! Corey

Ok I have never used a DVM before, I went out and bought one and tested my batteries like you said. I am not sure if I did it right but when I put it on the batteries with the truck running I got; DCV-12.8-14.0, ACV-28.2-30.0. Did I do it right?

I checked all the fuses in the fuse access inside and under the hood by the DS Battery all were good. I dont recall seeing one that was labeled DLC. Is it in the cab somewhere else or did I just miss it?Thanks, Corey

I cleaned all the grounds as well as the battery terminals last week.

Ok guys my truck has me stumped! Ill start from the begining and tell everything... My truck was doing the TC Lock and unlock at 45 MPH, after reading some stuff online I tried wiggling the black and white wire going from the battery to the alternator, stopped that problem I would just have to wiggle it every 3 weeks or so. The WTSL wasnt coming on either. So one morning(Months Later)I was leaving and my truck would idle fine but when I put it in gear I would have to push the throttle down like half way to get it to go, the truck felt like it had no power, it went to 3000 RPMs before it would shift, and when it did shift it felt like it was going to die. I pulled over like 1/4 mile from the house and turned the truck off got out wiggled that black and white wire from the battery to the alternator it ran fine. Went back home let the truck sit and about 6-7 hours later started it up, took off, and it did it again. My check engine light came on, I put some de electrical grease in the plug on that wire and it stopped, it ran fine, CEL went off for about a week, and my WTSL came on for the first time in a year. I noticed that it does it almost every morning now so what I have to do is start the truck let it idle until it warms up turn it off get out unplug and plug in the plug in the wire going from the alternator to battery and it will run fine. Also the truck will not start until the WTSL comes on which is about 10 sec after I turn the key. Now that it is doing it again the CEL came back on so I took it to pep boys to have the codes read. The technician said that I have either a fuse blown or a short somewhere because the code reader wont pull the codes off the truck. Im stumped I dont have any idea what to do next!

Its been 4 days and 300 miles and No problems with the TC! Hopefully it stays like that!Thanks again! Corey

The "IOD" fuse was blown. I will let you know tomorrow if i have the lockup problem again. Thanks Corey

I have a 99 Ram 2500. Lately the torque converter has been locking and unlocking, the other night I was checking the altenator grounds and realized my under the hood light was burned out, I took it out and now my Radio, inside lights, and cargo lights dont work... but the Torque converter doesnt lock and unlock anymore, It shifts like it did the day I bought it. Could these be related? I do have a deck, amps, speakers. I did notice that every now and then the amps would make a loud high pitched sound while accelerating. I like the torque converter part but dont know how long I can go without a radio... any suggestions?

About how much would a set up for a Walbro pump cost? Would it cost as much as a raptor or fass?

The Walbro pumps... Ive never heard of them til last week... they seem to be a good alternative. How hard is it to put it in and hook it all up? I'm all for saving money if they are just as reliable as the aftermarket pumps.

Okay thank you guys! I will change the lift pump this weekend! Corey

Okay I was just curious cause my origional lift pump lasted 9yrs and 150,000+miles. This one lasted 6months. What would you recomend I put on? I have no mods, the truck is 100%stock.

Hey Everyone, I noticed reciently that my lift pump is not coming on before I start my truck. I turn the key to the on position and no pressure from the lift pump. When I do start the truck my fuel pressure is 13-15psi drops to about 9-11psi wot. I know it isnt normal for it to do this, could it be a loose connection or you think it is the lift pump? Its a stock lift pump from Cummins Dealer I put it on about 6months ago. Thanks Corey
