Thanks john. So I got 0.115 with the truck running. Sorry I thought you meant without any wires hooked up. I didn't get to the hot wire test yet maybe tomorrow. I got a lift pump and tps coming tomorrow as well. Hopefully it's fixed but I'm not counting on it lol

Cross over is in good shape. All battery terminals have been cleaned and gone thru. With no wires hooked up on alternator I get 0.002-0.004 sometimes gets up to 0.010 but usually it's sitting around 0.002- 0.004 on AC setting. If it's the injection pump I just want to know. I can replace the pump in an hour or so so not that big of a deal to me. I work on all my own equipment and trucks so hard work is nothing new to me. I just wish it would say to me hey fix this lol. What do u guys think about the in tank lift pump? What if I put another lift pump on the side of the engine where the original was with leaving the in tank one in?

Ya I got that on my scanner too. The weird thing is that if I reset my tps it runs fine. I'm going to go see a buddy later that has the pump jumper cable and see what happens. I was thinking maybe a bad alternator?? It's charging fine and everything tho. Also it don't matter if it's cold or hot. The engine when I first start it up and it's reving around 900 at idle doesn't act weird but as soon as the idle comes down a bit it starts rough idling again. Also if I put it in drive or reverse and hold the brake it doesn't act up. If I put it in drive and just let it move under its own power it rough idles but the second I either give it a little throttle or hold the brake it goes away...

Hey guys I'm kinda new here. I been reading for months and now I have questions lol. So I got a couple 12v trucks which I love and now I bought a 24v. So far I like the truck but the electrical issues are driving me nuts. My truck still has the warranty installed in tank lift pump. I recently had the vp die so I put a good one on. Changed filter as well. Truck ran mint after. The next day i get this rough idle. So i check fuel pressure its around 13psi and never goes under 10. Scanned it and did the key trick. I have a 1693 with key trick and two 1688 with the scanner. EGT low and EGT high...there is no egt on this truck soo im confused there.. the truck runs mint just at idle it sounds like its got a cam in it lol. So i thought it was electrical problem. I did the WT ground wire mod and the blue wire fuse at the pcm. So I had the batteries disconnected for a bit doing that. I also installed a 150 amp breaker like mopar1973man suggests. Now after doing all this I started the truck and it was fine. Drove it for a day with no problems. Next day the rough idle came back. Also somehow it tripped the 150amp breaker 😬. What could cause that? I followed the instructions on WT ground wire mod simplified and never had any shorts or anything. If I go and unhook my batteries and then do a TPS reset the truck will be fine and runs and idles perfect for a day and then this comes back. Please help guys. I'm at a loss here. I love the truck but I'm starting to wish I stuck with a 12v. This trick is a work truck + my daily. I run my own excavation company and need this truck so quick reply are 100% appreciated. Thanks guys 🍻
